How it works
- Open the game file in any web browser: Chromebooks, laptops or your smartboard. No accounts, no student logins and no internet needed once it's downloaded.
- Pick Easy, Medium or Hard at the top. Students solve 12 problems, and every correct answer reveals part of the mystery picture. “New problems” makes a fresh set.
- Answers check themselves: a right answer turns green and fills in part of the picture, and a wrong one says “Try again”. Solve together on the projector or give each student the file. The teacher answer key always matches the problems on the screen.
- Each purchase includes the game file and a one-page Quick Start guide.
