Primer is a math game where you factor a number down to 1 using a few given prime numbers.
In each level you'll see a target number and several prime numbers. Clicking on a prime number will divide the target by that number, if the target number is divisible by it. If it's not divisible, you'll get a time penalty. When the target number gets down to 1, you win the level. If the timer ends before you manager to fully factor the target number, you lose.
What's the highest level you can complete?
