Your goal in this game is to organise falling blocks into rows. To achieve that move them to the sides or rotate them.
When the block reaches the bottom or you collect the whole row, you are rewarded with points. The level and speed of the game increases with time. Try to reach as high score as you can before you fill the screen with blocks to the top.
The game saves your best score in the career mode, so you can try to improve it next time.
