gridgame ^[1]
is a puzzle more than a game. THe object is to get a chain reaction to last as long as possible. I have a high score that was over 2400, however, I accidentally hit the wrong button on my browser and it cleared out my high score, so I do not have the exact high score that I received.

I liked it with the sound on; when I got long strings of chain reactions, it was giving me a science-fiction/newage sound. Very mellow and relaxing.
