In my previous article, I walked you through how I built my first DIY escape room from scratch. As a self-appointed Game Master, I was thrilled — and my friends had an absolute blast. Today, I’m sharing the actual puzzles I designed, plus a bunch more I’ve picked up over the years from creating escape room kits professionally.
Here’s the thing about escape room puzzles: if they’re too easy, nobody feels accomplished. If they’re too hard, people get frustrated and give up. The real skill is finding that sweet spot — challenging enough to feel rewarding, but achievable enough that your players don’t rage-quit halfway through.
After designing dozens of games played by over 21,000 people worldwide, I’ve learned what works and what falls flat. Here’s my full list of puzzle ideas you can steal for your own DIY escape room.
1. Papper på papper
This one reveals a hidden message using nothing but two sheets of paper. It’s simple to make and always gets a great reaction.
You’ll need two sheets — one with an intriguing, seemingly unrelated text (I used Italian in mine) and another blank sheet that acts as a secret decoder. On the blank sheet, carefully cut out small windows, positioned so that when you place it over the first sheet, each hole uncovers just one letter from the text beneath. Those letters, read together, spell out a hidden clue.
In my game, the concealed message was “check the hydrant,” where I’d hidden the next clue. My friends spent a solid five minutes trying to read the Italian text before someone thought to try the overlay. The moment they figured it out — pure magic.
2. OSYNLIG TEXT
This is one of those “wow effect” puzzles that never fails. There’s an invisible message on a sheet of paper that only appears when you dunk it in water. No chemicals, no invisible ink pens — just basic household items.
You’ll need: 2 sheets of paper, a pencil, water in a tray, and a smooth surface (a mirror works perfectly).
- Soak one sheet in water and lay it flat on the mirror.
- Place the dry sheet on top of the wet one.
- Write your secret message on the dry sheet with a pencil, pressing firmly.
- Throw away the dry sheet — you won’t need it anymore.
The pressure transfers a faint imprint onto the wet paper. Once it dries completely, the imprint vanishes. When your players eventually submerge the paper in water, the message reappears — and that’s the moment they realize you’re an awesome game master.
Prepare this one at least an hour before game time so the paper dries fully.
3. GPS-koordinater
This puzzle is one of my all-time favorites because it forces players to think outside the box — literally outside the room.
I hid a piece of paper with a big number on it. At least one person in any group will recognize it as GPS coordinates. Since my players were allowed to use everything in the room, smartphones were fair game. Any GPS app gets them to the destination.
“But wait — how can you leave the room during an escape room?” That’s the whole point. When I shifted the goal from “escape the room” to “find the hidden treasure,” a whole new world of possibilities opened up. Players aren’t locked in, and the GPS puzzle becomes one of the most memorable moments of the game.
The location I chose was across from my apartment, next to the high school entrance. I left an envelope with the next clue there. Since GPS satellites have a ±5 meter margin of error, pick a landmark that’s hard to miss and hide the envelope next to it. I put an electricity symbol next to the coordinate number as a hint, and burned the edges of the paper so it looked struck by lightning.
4. Map of the Apartment
Turn the space your players already know into a treasure map. Sketch a simple map of your apartment, mark a location with an “X,” and hide a clue at that exact spot.
The key is to make the hidden item genuinely difficult to find. You don’t want anyone stumbling on it before they’ve even seen the map. In my version, I hid a cell phone inside the couch cushions — it became the key tool for the next puzzle.
Watching my friends scramble around the apartment, map in hand, feeling like modern-day Indiana Joneses — that’s the stuff that makes hosting a DIY escape room so rewarding.
5. UV-ljus
UV lights are a staple in professional escape rooms, but you don’t need expensive equipment. A fluorescent yellow marker and a regular lamp are all it takes.
Making the invisible ink
Some people make a complete mess trying this — opening markers with pliers, boiling them in microwaves, washing them in hot water. That’s a recipe for a fluorescent nightmare all over your kitchen. Here’s my simpler method that works just as well:
Take an illustration or picture with a dark background and write your clue on it using a yellow fluorescent marker. Hang it on a wall where the lighting is a bit dim. The message stays hidden in plain sight until someone shines a black light on it.
Tip: Instead of a plain dark image, choose one that matches your escape room theme — like I did with the Leaning Tower of Pisa. Even in full light, the image acts as a decoy, camouflaging your message like a master of disguise.
Making a DIY black light
You can use a regular battery lamp or even a smartphone flashlight. Stick a piece of clear tape over the light, color it with a blue highlighter, add another layer of tape, color again — repeat five times. You’ve got a homemade black light that actually works.
6. Face Recognition App
This one brings tech into your escape room and always blows people’s minds.
I printed a bunch of Italy-themed pictures and scattered them around the room. One of them was a portrait of Leonardo Da Vinci. Hidden in the couch was a phone with a face recognition app installed (something like AppLock with face/voice recognition). I’d trained the app to recognize Da Vinci’s face from the portrait.
When players figured out they needed to scan Da Vinci’s portrait with the phone, a 4-digit code appeared on screen — the combination for the next lock. Full Mission Impossible vibes.
A couple of practical notes: “train” the app by scanning the printed portrait several times during setup. Test with different lighting conditions and distances. The quality can vary by app and phone, so do a dry run before your guests arrive.
7. Morse Code
Cracking Morse code makes you feel like Alan Turing breaking the Enigma machine. It converts light, sound, or tapping patterns into text — and it’s surprisingly easy to set up.
Here’s what I did: I installed a Morse code app on a smartphone, typed in the lock combination, and placed the phone where the ceiling light bulb normally goes. The phone’s flashlight blinked the code in Morse.
At some point during the game, players find a Morse alphabet card. Then it clicks — the flickering “broken” light isn’t broken at all, it’s a coded message. When they crack it and open the lock, the feeling of accomplishment is enormous. This isn’t an easy puzzle, but that’s exactly what makes it so satisfying.
Just make sure the phone battery can last at least an hour of continuous flashlight Morse transmission.
8. Tiny Tiny Tiny Text
This one will make your players squint like Clint Eastwood until they find the magnifying glass you’ve stashed in one of the locked boxes. Print your clue in Times New Roman, font size 2, on a regular sheet of paper. Make sure you use a good-quality laser printer — inkjet won’t cut it at that size.
It’s dead simple to prepare and always gets a laugh when someone finally realizes why they can’t read that “blank” piece of paper.
9. Custom Questions
This is a perfect way to wrap up your escape room, especially when you’re playing with close friends or family. Since you know each person well — their favorite song, food, obsessions, inside jokes — you can craft personalized questions that only they can answer.
One of my friends is obsessed with astronomy, so his question was: “How many planets are in our solar system?” Another is a huge NBA fan: “How many NBA titles has Michael Jordan won?”
Each answer is a number, and combined they form the final lock combination (in this case, 1990). This puzzle forces the team to actually work together — everyone has a piece, nobody can solve it alone. It’s consistently the most emotional moment in any game I’ve hosted.
10. Interactive Games and Tasks
Not every challenge needs to be a brain-teaser. When you think “escape room,” you picture logic puzzles and “aha!” moments. But to keep the energy up, you need to mix in some hands-on tasks that are more about doing than thinking.
Example 1: Finding a hidden key doesn’t require solving anything — just thorough searching. It’s a palate cleanser between harder puzzles.
Example 2: I put a clue in a room behind a chained, padlocked door — cracked open just enough to see through but not enter. In front of the clue, I placed a target illustration covering the padlock code. Players had to shoot rubber bands at the target to knock it off. When you hear “Yaaaaaay!” from the other room, someone nailed it.
These tasks set the pace. They give players a confidence boost between tougher puzzles and keep everyone engaged — even the people who aren’t great at logic problems.
11. Chifferhjul
A cipher wheel is two round paper discs attached at the center with a metal brad. Rotate them to the correct alignment and you can decode a secret message by translating letters from the outer disc to the inner one.
These have been used in real-world espionage for centuries, so they fit perfectly into themes involving secret societies, spies, or the military. Players might lose patience decoding long texts, so stick to a single word or short phrase — skip the spaces: “lookoutthewindow.” Numbers work too if you spell them out: “onefivetwo.”
Start by deciding your solution, then pick a key that defines the disc alignment (e.g., “A = s”). Set the wheel and encode your answer, letter by letter, from inner to outer disc. Hide the coded message, the key, and the cipher wheel separately around the room. Let players figure out they’re connected.
The uppercase/lowercase difference between the outer and inner discs is intentional — it helps players know which direction to translate. Using the same font on the wheel and clues also helps them make the connection.
12. Arranging Paper Strips
Perhaps the simplest puzzle on this list, but it works brilliantly for group solving. Write your secret clue in a big font on an A4 sheet, then cut it into strips about one inch wide. Make sure the cuts cross through the letters. Hide the strips around the room and let players reassemble them like a jigsaw.
The beauty is that players can use the letter shapes themselves to figure out the correct order. For a harder version, put only one letter per strip and add an image underneath that determines the correct arrangement instead.
This puzzle can carry more than just a code — you could hide an entire “secret document” that players need to piece together. We’ve used this mechanic in several of our professional games, and it always gets people huddled around a table working together.
Test it yourself before game day — whether this puzzle works depends entirely on how you make the cuts.
13. Måttband
Putting regular household items to creative use is a staple of DIY escape rooms. A measuring tape is one of those objects that players overlook until they realize it’s part of the game.
Here’s the setup: decide on a 3-digit code, then cut three pieces of yarn — each one the length (in centimeters or inches) of one digit. Use a different color for each piece and scatter them around the room.
Players won’t immediately connect the yarn to the measuring tape, so you need a visual clue. Put an image of a measuring tape in three colors on a piece of paper, with an arrow showing the order. Once they measure each yarn length and read the digits in order, they’ve got the combination.
14. Periodiska systemet
Classic substitution ciphers have a downside: some players recognize them instantly, which ruins the fun for everyone else. That’s why I like turning the periodic table into a custom cipher — it uses the same principle but feels totally fresh.
Each element has a one- or two-letter symbol, and you can combine them to spell out words. For example: NoTiFICaTiON. More words work than you’d expect.
Write out the element numbers as a sequence on a piece of paper (e.g., “102 81 9 53 20 81 8 7” — don’t forget the spaces, they matter). To connect the numbers to the table, you could color-code them to match the element category colors, or display each number in the upper-right corner of a square, mimicking the table’s layout.
15. Labyrinter
Classic puzzles like mazes should be used carefully in escape rooms — if players already know the rules, the puzzle becomes a chore rather than a discovery. But with the right twist, a labyrinth works beautifully.
Solve the labyrinth yourself first. On a fresh copy, write the letters of your answer along the correct path. Fill in random letters everywhere else so the correct path isn’t obvious. Players solve the maze and read the letters they pass through to reveal the code.
Quick to make, satisfying to solve, and it brings a nice change of pace between heavier logic puzzles.
16. MATCHA MÖNSTER
Many escape room puzzles rely on players making an intuitive connection between clues that share a property — color, shape, size, or pattern. This puzzle type forces that connection.
Write the letters of your solution in a random arrangement within a distinctive grid shape. Extend the grid with decoy symbols. That’s your first clue.
The second clue uses the same grid shape, but with circles instead of letters. The circles that correspond to solution letters are numbered to indicate their order in the answer word.
In our example, we used the word ROSE — four letters scattered in a recognizable grid, with a matching numbered grid hidden behind a lock. Leave the first clue in plain sight and lock the second one away behind another puzzle. Players have to solve one puzzle to get the tool for the next — that’s the kind of cascading design that makes escape rooms addictive.
17. Extract a Secret Message from a Letter
Starting an escape room with a letter that sets the scene is a great way to deliver the story. It’s also the perfect place to hide your first clue using steganography — hiding information in plain sight.
Write your introductory letter first. Then decide on a hidden message (e.g., “UNDERTHEHAT”). Go through the letter and mark each letter of the secret message as you encounter it:
YoU will laugh (and you are quite welcome) wheN I tell you that your olD acquaintancE is tuRned sporTsman, and Has takEn tHree noble boArs. “WhaT!” you exclaim…
You could capitalize the relevant letters, write them in a different color, omit them entirely, or mark them in some other creative way. The players who notice the pattern first get to feel like codebreakers.
18. Hide It in the Matchbox
Sometimes you need to hide a clue so well that a normal room search won’t find it — but a targeted hint later in the game will send players right to it. The “it was here the whole time!” moment is one of the best reactions you can get.
A matchbox is perfect for this because it’s such a mundane household item and it can be used in several clever ways:
- Encode information in the arrangement of matches themselves
- Write a clue on the bottom, hidden beneath the matches
- Hide a tiny item inside
- Write on the inside of the cover
To direct players toward it later, make “MATCHBOX” the solution of an earlier puzzle. Simple, effective, satisfying.
19. Crossword Clues
Full crossword puzzles are too time-consuming for an escape room, but borrowing the clue format is a smart move. Instead of giving the answer “MATCHBOX” directly, disguise it as: “SMALL FIERY CONTAINER.” You can use online crossword solvers to generate these by entering the solution as known letters.
For word nerds, try cryptic crossword clues. The simplest form hides a word inside the clue itself:
ELDIGA STOCKAR GÖMDA I PÅTÄND STICKAD TRÖJA
The phrase “hide in” signals there’s a word hidden in the following letters. Ignore the spaces: haZMAT CHESt → “MATCHES,” which fits the definition “FIERY LOGS.”
I created that clue by splitting MATCHES into MAT and CHES, then searching for words ending with MAT and starting with CHES. Making good cryptic clues is a puzzle in itself — gauge your audience before going down this road.
20. Telephone Spelling Alphabets
The NATO Phonetic Alphabet — Alfa, Bravo, Charlie, Delta, and so on — was designed for military radio communication where words that sound similar could be confused. It’s 26 code words that each represent a letter, and it makes for a fantastic escape room puzzle.
Record a clue or secret code using the NATO alphabet and play it through an old tape recorder, a Bluetooth speaker, or even your phone’s voicemail greeting. Leave players with just a phone number as a clue. When they call it and hear “Echo-Oscar-Papa-Echo-November,” they’ll need to figure out what those words mean — and a NATO alphabet reference card hidden elsewhere in the room completes the puzzle.
21. UNDERSÖKNING
Research puzzles ask players to piece together conclusions from documents, photos, or evidence. Think murder mystery — but you can adapt it to any theme.
Here’s a scenario I designed: the game’s narrative involves identifying a cyber-attacker. Players have security camera footage (a single printed photo of someone’s face) and a stack of photocopied passport pages from six hotel guests. They need to match the face to the passport to find the name. The name becomes the code for the next lock.
What makes this work is that it feels like real detective work. Players aren’t solving an abstract logic problem — they’re comparing evidence, eliminating suspects, and drawing conclusions. We’ve used variations of this approach in several of our professional kits, and it’s consistently one of the most immersive puzzle types.
22. Logic Puzzle
I saved one of the best for this spot. You know those logic puzzles where you match three kids to three desserts using a few clues? Same principle, but escape-room-ified.
Picture this: from an earlier clue, players know the secret code is the year a geography professor visited the Taj Mahal. In his “office,” there’s a world map with pins in seven wonder locations, and seven year cards on the floor (1967, 1971, 1974, 1976, 1982, 1989, 1992). The professor’s notebook contains clues like:
- “I didn’t go to America before 1982”
- “I went to Asia only in even years”
- “I went to China right after Jordan”
From just these clues, you can determine the Taj Mahal visit was in 1976 — even though some other pairings remain ambiguous. If you’re worried players will brute-force the seven possible combinations, make the code the last digits of four specific visits (“Italy – Jordan – China – India”), which bumps the possibilities to 360.
The reason this works so well in an escape room is that it reflects reality within the game world. A geography professor would have traveled, and the cards look like they simply fell off the map and need to be restored.
23. Laserlabyrint
If you’ve ever seen a heist movie where someone dodges laser beams to reach the vault, you know why this puzzle is so appealing. The good news: you don’t actually need lasers.
I’ve set this up using red yarn or string stretched across a hallway at various angles and heights — taped to the walls, doorframes, and furniture. Players have to navigate through without touching any of the strings. If they do, an “alarm” goes off (you can use a bell, a buzzer, or just shout dramatically).
At the end of the maze, place a clue or a key. For an extra layer, position a small puzzle at the far end that players have to solve while crouched between the strings — which is both hilarious and stressful for them.
This puzzle is pure physical fun, and it photographs incredibly well. Your players will be posting Instagram stories from this one. Just make sure the strings are firmly secured so nobody trips.
24. ORDSÖK
A word search grid tied to your escape room’s theme can be more clever than you’d think. The trick is making the puzzle serve the game, not just fill time.
Here’s how I use it: create a grid with 8-10 theme-related words hidden in it — for a pirate theme, that’s “treasure,” “ship,” “compass,” “anchor,” and so on. But here’s the twist: after finding all the words, certain leftover letters in the grid spell out the next clue. Players who just casually circle words without thinking about the remaining letters will miss the hidden message entirely.
You can make it harder with a bigger grid, smaller fonts, or words placed backwards and diagonally. I’d recommend keeping the word list to under 10 items — any longer and people start zoning out.
25. LJUD-PUSSEL
Sound adds a whole extra dimension to an escape room that most DIY setups overlook. I’ve used audio puzzles in a few different ways, and they always catch players off guard.
The simplest version: record a message on your phone that contains a clue — maybe a series of numbers spoken in a strange accent, or a phrase with emphasized syllables that spell something. Hide the phone in a drawer or inside a box, set it to play on a timer, or make it the ringtone that triggers when players call a specific number.
A more advanced approach: play a sound effect (a bird call, a clock chime, a musical note) and have it correspond to a letter or number based on a reference sheet hidden elsewhere. Players need both pieces — the audio and the decoder — to get the answer.
Keep audio clues short and repeatable. There’s nothing worse than a 30-second recording that players can only hear once and then argue about what they heard.
26. Cryptex
If you’ve read The Da Vinci Code, you already know what a cryptex is — a cylindrical container with rotating letter discs that locks something inside until you spell out the correct combination. It’s one of the most satisfying physical props you can include in a DIY escape room.
You can buy cheap cryptex replicas online for $10-15, or build one from a PVC pipe and cardboard discs if you’re feeling crafty. Either way, the concept is the same: players rotate the rings to spell a word, and the cylinder opens to reveal a key, a note, or the final clue.
What makes the cryptex work so well is the physical sensation — the click of the rings, the moment it opens. Digital puzzles are fine, but nothing beats something tactile that you hold in your hands. I recommend placing the cryptex late in your game as a climactic “final lock” moment.
Scatter the letters of the solution across earlier puzzles — each solved puzzle gives one letter, and the cryptex brings them all together. That’s the kind of layered design that makes players feel like they’ve truly earned the win.
27. Mirror Writing
Leonardo Da Vinci famously wrote his notebooks entirely in mirror script. Stealing this idea for an escape room is almost too easy — and it’s one of those puzzles that makes players groan and grin at the same time.
Write your clue backwards on a piece of paper. Not just reversed word order — actually flip each letter. It’s unreadable at a glance, and most people won’t immediately think to hold it up to a mirror. Place a small mirror somewhere in the room (inside a locked box works well) and let the connection happen naturally.
For a themed version, frame the mirror writing as a “diary entry” from a historical figure. I once wrote a clue in mirror script on parchment-style paper and sealed it with wax. The moment someone held it up to the bathroom mirror and shouted the answer — that’s the kind of reaction you host an escape room for.
28. Blacklight Jigsaw
This combines two puzzle types into one satisfying experience. Take a regular jigsaw puzzle (25-50 pieces max — you don’t want this eating up half the game) and assemble it ahead of time. On the completed puzzle, write a hidden message using a fluorescent marker, then break it apart again and scatter the pieces.
Players assemble the jigsaw thinking it will reveal a picture clue. It does — but they’ll notice the image alone doesn’t make sense as a code. The real answer only appears when they hit the completed puzzle with a blacklight, revealing the fluorescent message underneath. Double puzzle, double satisfaction.
I like using this early in a game because the jigsaw is a familiar, non-threatening activity that gets the group warmed up and working together. The blacklight reveal then sets the tone: “nothing in this room is what it seems.”
29. Book Cipher
If you have a bookshelf in your escape room (or can set one up), a book cipher is elegant and surprisingly hard to crack without the key.
Pick a specific book and write out a series of number triplets: page number, line number, word number. For example, “42-7-3” means page 42, line 7, third word. Each triplet gives one word of the message. String them together and you’ve got a clue that’s impossible to decode without finding the right book first.
Leave a subtle hint about which book to use — maybe a highlighted title in a “to-read” list, or a bookmark sticking out of one specific book. The beauty of this puzzle is that it uses a real object in a way players wouldn’t expect. I’ve used a cookbook, a children’s storybook, and once even an IKEA catalog. The more unexpected the book, the more memorable the puzzle.
30. Color Mixing
This one uses basic color theory and it’s surprisingly tricky for adults who haven’t thought about primary colors since grade school.
Set up three transparent containers with colored water — red, blue, and yellow. Provide a clue that references secondary colors: “The first digit is the color of envy. The second is the color of a sunset. The third is the color of royalty.” Players need to figure out: green = red + yellow (the digit is where those two containers are positioned), orange = red + yellow, purple = red + blue.
You can take it further by actually letting players mix the colors using small cups and droppers. When they get the right combination, the mixed color matches a swatch on a reference card that reveals a number. It’s hands-on, visual, and feels more like a science experiment than a traditional puzzle — which is exactly why it works so well, especially with kids.
Tips for Designing Great Escape Room Puzzles
After years of designing games professionally, here are the principles I come back to every time:
- Mix difficulty levels. Alternate hard logic puzzles with easier tasks. If players hit three tough puzzles in a row, energy drops fast.
- Chain your puzzles. The best escape rooms have puzzles that feed into each other — solving one gives you a piece needed for another. It creates momentum.
- Always test first. What seems obvious to you (the person who designed it) might be impossible for fresh eyes. Run your game with at least one test group.
- Build in a hint system. Even professionals get stuck. Have 2-3 hints ready for each puzzle so you can nudge without spoiling.
- Make it personal. The puzzles that get the biggest reactions are the ones that include inside jokes, personal photos, or custom questions. A generic puzzle is fine; a personalized one is unforgettable.
Last But Not Least
Use your imagination. Take your creativity to the next level. Try adding unusual ideas. Wake up your inner child.
My escape room crew instantly felt how much love I put into the game. It wasn’t decorated with expensive items, it didn’t include fancy gadgets, and it wasn’t 100% perfect. But all of us — including me — had the best time of our lives, better than any professional room we’d been to. Positive energy, smiles, laughter, funny photos of my crew hanging around the room, inside jokes woven between the puzzle lines… you can’t get that experience anywhere else except in your own DIY escape room.
People are often unaware of how creative they really are until they put their heart into something they love. So go build something your friends will talk about for years.
