- In Tuper Tario Tros, you're playing Mario and Tetris at the same time, in the same place. The tetris blocks that fall become the terrain that Mario is running and jumping on. If Mario can't make it across a gap, switch to Tetris mode and build him a bridge out of tetrominoes. If you can't find anywhere to put your current block, switch back to Mario mode and move through the landscape until you find a more favorable area.
- First-Person Tetris is more or less what it sounds like. It's tetris but you are the tetris block! Warning: This game will make you dizzy and perhaps naseous if you play it enough.
- gnop (yes, that's "pong" backwards) is a clone of Pong, except that you are the ball. Perhaps it was inspired by First-Person Tetris. While playing this one, I imagine that some kid in the 80s with a bad haircut is playing pong, and is wondering why the ball refuses to follow the laws of physics.
- Lastly, I just discovered TetriSnake which is of course a tetris game where instead of blocks, you have little snakes. Which is cool because they can be any shape you want if you can succesfully maneuver them into that shape.
- UPDATE: Found another one: Anti-Pacman, where you control the four ghosts. In fact, this is part of an Anti-Games series, but of all the ones listed, Anti-Pacman sounds like the coolest.
Old games with a twist
I love casual games. I don't know if there's a strict definition for a "casual game" but I would say it's a small, simple game that you can learn very quickly. The kind of free flash games you find at places like Kongregate or Armor Games or Jay is Games. Lately I've seen a few fun games that are all twists on very familiar games, or combinations of them.
