It is a simple touch puzzle game.
There are some blue panels in a square mass.
It puts together and five panels reverse when ..panel.. touching the panel, the top and bottom, and a right and left panel.
When all panels are erased, it is a success.
The size of the mass can be chosen from 4×4, 5×5, and 6×6.
My favorite image and the image taken with the camera then and there can be used for the background image.
The number of lowest actions is recorded, and aim at a less number of actions, please.
