This game is very tricky. You have to swap the red guys over to the right while moving the blue guys over to the left. A great thinking game!

This is like the classic board game, Othello. The last one with the most of their color wins. You have to plan ahead because one move can change everything.

The cool thing about this game of pool is that you get to see the geometry of the shots you're lining up! Plan your moves carefully and clear the table.

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.

A great level puzzler. Control multiple magicians while you collect playing cards and avoid hazards to get through each puzzling level.

This classic logic game takes a little math and LOTS of thinking. You have hour glasses with different amounts of sand. You need to use them to find another time.

This game is like Bricks Breaking, but you have to match up the debt block with money blocks of the same color. Be sure to avoid the credit cards blocks!

This game is like Rush. You have to slide a bunch of blocks around to get the one block out. Lots of great thinking on this one.

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!

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