If the user answers a question incorrectly, the status level is reset to 0 and the user starts the module over. Once a module is unlocked, the user can practice those types of problems in Free Play.This app generates practice problems for the user to solve. Solving 5 problems in a row in a module "unlocks" the module for further practice (in freeplay mode). Working through the Gap Check mode provides a reference level for accuracy and time. As the user unlocks levels and practices solving the problems in Free Play mode, improvement against this reference level can be monitored.This app makes use of the Game Center. Achievements for speed and accuracy can be unlocked, the Leaderboard can be used to compare scores, and users can challenge others to beat their times or unlock achievements.
