Up to 15s provides a fun way to memorize basic math facts from 0 to 15 and the squares and cubes from 0 to 15.
The player has several options including which operation, which number or numbers, and the "Up To" value (10, 12, or 15).
The game has five difficulty levels for the basic operations: Beginner, Intermediate, Advanced, Expert, and Genius.
The player earns three points for each math challenge completed correctly on the first try, two points for the second try, and one point for the third try. Any attempt to answer the challenge after that will earn zero points. Every math challenge has its own time that is displayed on the statistics screen along with the challenge itself.
The total time on the stats screen has been updated to show the correct amount of time expired on the stats screen when the count down timer is selected. Version 1.1 showed the current time of the timer, which was zero if the player played until the timer was finished.
