13 is a arithmetic based puzzle game. Select the operator that will cause the given numbers to equate the goal result. Completing this in a low number of turns will earn higher scores.
Reaching the goal number will unlock fun Math facts. They're fun! FUN!
13 was inspired by the games my High School math/physics/engineering teacher dad would show my sister and I when we were trying to kill time wait for our food at restaurants.
So with that in mind...
It's definitely more fun
than doing nothing at all.
