3D Mersi

A three-dimensional version of Tetris, in which the player's task is to fill a well seen from above with various block shapes. Filling the entire level will cause it to disappear giving room for more falling blocks. The game has five difficulty levels to choose from, varying in the speed at which the blocks fall and the number of different shapes. The blocks can be rotated in any direction, allowing them to fit correctly. Filling the entire well completes the game.
