In the Prime Out! game, you earn points by building numbers from primes - one step at a time. You will see how prime numbers are the 'atoms' of arithmetic - the basic building blocks of the numbers we count with every day. You can play Prime Out! in many ways: with small or large numbers; by yourself or with a friend; as a leisurely game or a fast-paced timed game! No matter how you choose to play, you will have fun while strengthening your math knowledge and skills. But watch out - if you play often, you might just start thinking about numbers in a whole new way!

In the Integer Target game, your goal is to get the lowest possible score by getting your cards to add up to a number as close as possible to a target number that you have chosen at the beginning of the game. The catch is that your cards may have either positive or negative numbers on them, so you have to be very careful when you devise your strategies! Things may not work the way you expect at first!
