Tetrollapse Advanced by GameGlade.com is a new and enhanced version of Tetris with 50 levels and different shapes to clear. The game is available online and for download.

However, GameGlade.com has added their own spin to the classic game, changing the objective of the game entirely. Not only must you avoid filling the board, but you must also "sort out" the figures that are already on there. If a figure disappears, you will advance to the next level where yet another figure is preparing for you. With 50 different levels to complete, you're sure to never get bored.
The shareware version of the game can be played both online and downloaded onto your computer. However, if you want to unlock all 50 levels and experience the game in full screen mode, you'll want to upgrade to the registered version. With so many different options, Tetris by GameGlade.com is definitely worth a test run.
