The story of the game is simple. Square blocks are falling from the top of playing field. The playing field has four columns and there are six different colors of blocks.
You can move the falling block to the left and to the right. When three (or four) blocks of the same color happen to be inline next to each other (horizontally, vertically or diagonally), theyÆll disappear.
Your task is to drive the falling block to the place where it can line up with other blocks of the same color. If you do not remove enough blocks, they will start to pile up and soon fill the whole field. This is when the game is over.
The game starts slowly at first and speeds up as you go to higher levels.
