The rule is simple! Rotate and drop blocks to fill in space in underlying layers of blocks. Once a layer is completely filled in with dropped blocks, it will be cleared. Score high with a chain reaction!
The operation is simple! Flick left or right to rotate blocks and down to drop. In Keypad Mode, you may play the game with the buttons on the screen just like a traditional controller of game devices.
Two different types of game modes are provided. In "Standard Mode", keep on clearing layers of blocks thoroughly so that stacked blocks do not reach the End Line. In "Extra Mode", which is a hard mode for advanced players, rotate and drop each block leaving no space between the block and underlying blocks to form a large mass called "Material".
