Pixus
Pixus starts with a pile of blocks of varying colors. Your job is to make the blocks disappear by drawing lines under the blocks that correspond with the colors. If the majority of blocks on bottom are blue, you would draw a blue line to cover the span of the blue blocks. Then you would work on the next color, and keep going through colors until the blocks are gone. It's a little like Tetris, but you're matching colors instead of just making lines. Strategy will be important, as blocks will start falling when time starts to run out. If any block hits the bottom, your game is over!
