Find Number is an attention training tool. The player searches for the specified number. There are four levels to the training. In the First Level, you must find all instances of the number '3'. In the Second Level, find numbers placed to the left of '3'. For the Third Level, find all 7's horizontally to the left of any '3'. Finally, in the Fourth Level, find all even numbers placed horizontally between a '3' and a '7'. The game will monitor your attention in the background.
Afterwards, the completion chart evaluates the trends of your attention level.
