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.
Each student types their name and picks a level on the world map. Levels get harder after 3 right in a row and easier after a miss.
Students play on their own device. Missed problems come back for a second chance, and when they finish, the skills report shows every skill as Mastered, Still learning, Needs help or Not reached, with a check code for the teacher.
Each purchase includes the game file and a one-page Quick Start guide.
