What this template contains
step 1 · Numeric code (PIN)
The freezer door
🥶 The freezer only opens for the thing it hates most: the boiling point of water.
⌨️ Its keypad is American.🧮 Take 100 °C, multiply by 9, divide by 5, add 32. Three digits.
step 2 · Grid 4x4
The sample rack
🧫 Each missing tray had exactly two neighbours, side by side, never diagonal.
Every other tray has three or four.🎯 Select the four empty slots.
step 3 · Ordered switches
The vents
💨 Five vents, numbered 1 to 5 from the left.
☣️ Purge only the ones that work, counting down like a rocket launch: highest number first.
step 4 · Sudoku
The airlock panel
🔒 The airlock wants its grid back.
🧩 Each row, each column and each 2 by 2 box holds 1, 2, 3 and 4 exactly once.
🔬 No guessing here: scientists deduce.
step 5 · Wordle
The word on the screen
🔡 Five letters, six guesses: what was this lab studying?
🔬 Tiny, contagious, and your laptop is scared of it too.
Ideas to make it yours
- Make the final word your product or project name
- Run it as a 15-minute icebreaker before a workshop
- Swap the vent note for a rule from your own safety procedure

Questions about this template
- How does the 15-minute clock work?
- The clock is kept on the server, so refreshing the page does not reset it, and each device gets one run.
- Do players need to know any science?
- No. The first code gives the conversion formula, the rack and the vents are pure logic, the sudoku is only 4 by 4, and the last word is a Wordle-style guess. Every step also has an optional hint.
- Can several teams play at the same time?
- Yes. Give every team the same link or QR code. Each team plays on its own phone against its own clock, so you can see which one gets out of the lab first.
- Is this template free?
- Playing it and editing it in the builder are free for everyone, and players never pay. See current plans and features on the pricing page.
- Can I change the answers and the texts?
- Yes. Every code, clue, hint and piece of locked content opens in the builder, and nothing is saved until you publish.
- What do players need?
- A phone or a computer with a browser. They open your link or scan your QR code, and never create an account.
- How long does it take to play?
- About 15 minutes, from the first lock to the locked content.
