The player has a field with lots of squares – there are sectors of the field. Additionally, the player has many figures of a different shape – crosses, «L», or even simple squares. They must be placed on the field so that there are no empty cells. Once the figure was placed it can’t be removed. If the player did everything correctly, they will pass the level. If not – they should play one more time. The game is designed in calm colors and is controlled by the mouse or sensor display.
