Think you're pretty good at Tetris? Well playing against a computer is one thing, but how do you think you'd fare playing against other hard-core Tetris players? Blockles is an on-line competitive Tetris-clone from the makers of online dating site i'minlikewithyou. And it's the quickest way we're aware of to find out if you suck at Tetris.

Gameplay is pretty much exactly what you'd expect. You use the arrow keys to rotate blocks and hit the spacebar to drop them quickly to the bottom of the screen. You can either join a game hosted by another user or create your own if you're a registered user. Matches can have just a few players, or as many as 8.

There are a few interesting aspects to the multiplayer gameplay. For example if you break two or more lines apart at the same time, each of your competitors will get a new line of blocks. That makes Blockles a bit more fast-paced than the original Tetris game, but also a bit more addictive.
