The Rules

The shape and method of operation of the block piece, has been inherited from Tetris, but the rules differ greatly.

The minimum unit block has three colors red, blue and yellow.
Multiple “fixed blocks” are established from the start. In addition, one shiny “flash block” is red, blue, or yellow.
Players rotate the “moving block”  falling one by one from the top of the screen. Moving blocks are fixed in the field and drop to the floor of the other blocks and fields.
The moving block is composed of one of four blocks with three colors. Shapes are similar to Tetris, but both width and height square piece made up of two blocks do not appear. The other two or three small blocks are in contact at the corner, there are also shapes that are connected diagonally.

Block piece

Blocks regardless of type, disappear and the same color line up horizontally or vertically into three or more. Blocks don’t just  disappear by filling in the gap without blocking the lateral line as Tetris.
If you turn off the flash block, they all disappear with fixed blocks of the same color. However the moving block does not disappear. Stage is cleared by erasing all of the flash blocks.
If you turned off the blocks of the same color six or more side-by-side, moving blocks of the same color disappear. Flash blocks and the fixed blocks do not disappear.
When the block is gone, the moving block  becomes a chain.

Fighting mode

Erase all of the fixed blocks and flash blocks before your opponent. Attack your opponent by turning off the flash block in two of the chains.

When erasing flash blocks to lower the shutter on the opponent’s field top, it is possible to narrow the field. Also, it is possible to raise the shutter of their fields.
