Algebrain is a game you can play for free. Click here to try it. It's in the Beta stage, so please give me feedback.

It's a video game about algebra, inspired by puzzle games such as Tetris / Tetris Attack / Dr. Mario / Puyo Puyo. However, when played 2 player, it's a cooperative game.

It's not intended to teach you algebra, but to train the brain pathways that solve algebra equations, while (most importantly) being fun. It's intended for people who have already learned the concepts of algebra, but will hopefully provide some training or practice in solving simple equations. I got the idea after noticing similarities between puzzle games and algebra equations.

You can try the tutorial to learn how to play - if the tutorial didn't teach you, that feedback would be helpful too.
