The game is same as the classic Tetris, but in this one, you play with 3 grids instead of one. Before your block reach the red line, you can select the grid you want to put the block in.
You can do combos and keep any next block for later use.
Left, right and down arrows or [A] [S] [D] > Move your block left, right or down faster.
Up arrow or [W] > switch the keeped block with the next one.
Numpad 0 or space } flip the block.
Enter > Pause the game and give access to sound options.
[Tetris Thrice only]: Numpad 1, 2 and 3 or [Q] [E] > Change grid.
In options: you can choice from 5 musics, enable or disable sounds or music.
You can choice wich level you want to start, from level 1 to level 10.
Please let me know what you dislike if you vote low on my game.
I know that the block doesn't flip if something is blocking it.
