It consists of course where you must answer the mathematical operations as quickly as possible. There are 10 levels of difficulty.
Currently, the data is used for an educational research study. So there are two versions of the game: one with obstacles and another one without them.
During the race you can see the shadow of the player who holds the record for each level or the user's own.
