If you think all puzzle games are the same, or that you've seen everything that TETRIS games have to offer ? think again. A grand addition to the family, Tetrisphere eclipses its predecessors, challenging you to explode your way to the center of an enormous sphere. Choose from a long list of robot characters, each with different personality traits, that includes Wheels, Jak, Rocket, Gear, Turbine, and Stomp. The 3D game play takes place over 300 different levels, each more challenging than the last. The main objective is to pull the right combination of pieces out of a giant, rotating ball, forcing an explosion that will further open the gap to the ball's core. Each time you reach the center of the ball, you advance to the next level. If you get mixed up or take too much time figuring out how to make the combo, a block gets added to the outer part of the ball, making your job that much more difficult. Not only that, but three such mistakes will end your game entirely! With excellent audio-visual presentation and game play that's doubly worthy of the TETRIS name, this game is already a classic.
