Splash Back: The next Tetris

Confession: I'm a puzzle game junkie. As such, I can spot good puzzle games in seconds. And this is one: Splash Back
Simple concept, easy to learn, difficult to advance too fast. The type of game that will fill your gaps when you're writing papers and get stuck. (That's where I am right now...)

Yes, I should complete the post about Living Gameworlds before the next edition...
