Primes!

"Primes!" is a math game where you run against the timer decomposing numbers into their prime factors.

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.

If you clear the screen, you get extra time, the difficulty level increases and a new set of balls falls.

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

I wonder if this could be helpful in primary schools, like an engaging way of teaching prime factors. Maybe time will tell...
