Press 'New Game'. The page will display a number in the big yellow square. Your job is to enter the number's prime factors as quickly as you can!
The clock is ticking! Hit enter after typing in each factor.

When you are done, the page will say 'Good job!' and show you how long it took. It will show the original number as well as
its prime factors

Hints: Look at the diagram in the yellow box. You can see the prime factors by looking at the way the dots are arranged.
For instance if you see 3 dots in a triangle, you can bet that 3 is a prime factor.

Some numbers are easy and fast to factor, some are harder and take more thought. Try doing 5 in a row and then compare your total
time with your friends.
