This is like our game, Twins, but we put numbers on the balls. You have to match up numbers (like in our game Shisen) to make the correct sums.

I thought this was impossibly hard at first. The key is to fill in all single squares first, then look for doubles and up. Cool that you can ask for hints!

Compete against the computer to see who can pick numbers that add up to 15 first.

This is just like our Marble Lines game, but we've made it an addition game. You have to shoot the ball that makes the right sum.

I've played this game until my arms were sore. It's great arithmetic practice while you get to shoot stuff. Can life get much better than that?

Stack the colored orbs so that they add up to 21. How long can you last? Good for practicing your addition skills!

This games let you arrange playing cards and math symbols to make 24.

This is a Pac Man type game, but you have to eat the monster that solves the math equation.

Click on numbers that add up to the given number on the right. You'll have to work faster and faster as each level gets harder and harder!

In this timed game, how fast can you pick out numbers from the grid that complete the missing spots in an equation?

Click on the fraction squares to make pairs that have a sum of 1... and do it as fast as you can!

In this game, you're given an arithmetic problem to solve... Once you find the answer, you have to find it on the grid of numbers - like in a word search game.
