The Big Freeze has iced every lock at Snow Owl Ice Camp and blown out its twelve picture lanterns. Without the lights, the supply sled cannot find its way home. Snow Owl Ice Camp is a math escape room with 230 pyramid locks, and it comes in two forms: an interactive game for a web browser, and a printable PDF of the same adventure.
How it plays
- Twelve huts, each with ten brick locks. Every lock is a number pyramid.
- Each open lock gives a token with a digit, and four tokens open the hut's lantern box.
- Inside waits a lantern. Solve, join the dots made by your answers, and the picture lights up.
- There are stars for every lock, a camp map, a lantern collection, a certificate with your name and six 60-second Snowball Sprints for quick mental math.


Offline, private and honest about devices
The game is one HTML file. It opens in a web browser after you unzip the download, checks your answers, gives three-step hints and saves your progress on your own device. It works offline: no internet, no account, no ads, and nothing is collected or sent.
- Windows, Mac and Chromebook: yes, in a current browser such as Chrome, Edge or Firefox.
- Android phones and tablets: yes, open the file with Chrome.
- iPad and iPhone: Apple's Files app does not run games from a file, so you would need a computer or a file-viewer app with its own browser. The printable PDF works on every device.
