This game is a game that erases the same color that queues up length/side/diagonally stone.
The time limit is 60 seconds.
The stone can be exchanged for the next stone. It operates it with the drug at this time.
It returns to former position when the stone cannot be erased after stones are exchanged.
The stone above drops when the stone disappears. At this time, the chain occurs when the color queues up.
The score changes by the number and the chain of the stone that disappears.
The "Clear Same Color" button can be used by erasing five stones or more at the same time.
This can erase all the same color stones.
The time limit increases on a certain condition.
Moreover, an almighty stone appears, too.
Please enjoy the chain.
