Take blocks from the left and throw them to the right. If a block hits one or more of the same type, they will all be removed. You can take more than one block of the same type from the left before throwing. More blocks will appear from the sides. If the rows of blocks reach the lines in the center area of the screen, the game will end. You will score points for each block that you remove. Removing more than one block at a time from the right side will add bonus points. Use the 2 and 8 keys to move the cursor. Press 4 to pick up a block from the left and 6 to throw it to the right. You can pause the game and return to the main menu by pressing the Cancel button. By selecting Options from the main menu, you will be able to change the Difficulty: Easy, Medium or Hard. Harder levels have more block types and new blocks appear more frequently.
