## Description

&quot;Primes!&quot; is a math game where you run against the timer decomposing numbers into their prime factors.<br><br>You start with 30 seconds, and a pile of number balls. The game sets you a target, and you must choose its factors (e.g. target = 12, factors = 2,2,3) in order to destroy them. If you press the wrong factor, the target will explode and add its correct factors to the pile.<br><br>If you clear the screen, you get extra time, the difficulty level increases and a new set of balls falls.<br><br><br>The game comes with a Ranking of the 5 best scores, so you can see how close you are to be the best factor decomposer in town :D<br><br><br><br>I wonder if this could be helpful in primary schools, like an engaging way of teaching prime factors. Maybe time will tell...
