Tetron is Tetris, but on a cylinder. Means: instead of viewing from front toward a row of blocks and instead of moving the actual block directly, you’ll have to move the cylinder so the blocks can be placed whole around it. But this is also a negative aspect of the game, because of the high amount of "holes to be filled" it takes time to clear a "line". A good (very good) thing is the recommended hardware (also good speed on older machines) and the very small filesize of 340kb. Unfortunally there’s no music and only a few sounds. But if you’re a fan of Tetris and his variants, just download and play Tetron!
