It's a puzzle game that you can learn easily and enjoy without burden.

◆ Game rules
Touch a blank quad (gray) block to destroy any quad block of same color in the horizontal and vertical directions. The more quad blocks of the same color are removed at the same time, the higher the score.

◆ Game modes
There are two types of games, 'slow games' and 'time-limited games'.
In a time-limited game, you can destroy the quad blocks that contain a clock to acquire additional time.
Choose your own mode and enjoy it.

If there are no more quad blocks that can be destroyed or the time is exhausted, the game will be over.
