There are a lot of puzzle games that either live in the color-matching camp or the Tetris camp. Ziczac, a small freeware puzzler, mixes the camps into a game with simplistic graphics and an interesting premise. Don't expect anything beyond a very simple puzzler concept game, however.

Ziczac is based around either grouping blocks into squares of at least 2x2, or by building loops with the blocks. The default matching gives you a fair amount of points, but creating a loop with another color inside is the way to go in terms of scoring. It's also an entry in the procedural generation competition at TIGSource, and it's a fun way to cool off and relax for minutes at a time. It even has procedurally generated music! You can download it through the TIGSource forums.
