The aim of the game is to put the squares on the circled area of the game board. The grey circles may have the squares of any colors, and the colored circles may locate the squares only of the same color. There are three colors: red, green and blue. At the beginning of the game, on the board there is only one square with four dots (it is irremovable from the board). Also, beside the game board there is another square (which can be moved). It can be moved around the game board in or against clockwise order. Tap it after you have chosen the needed side and position of the moved square, so the moved square runs until it bumps into the other squares on the game board. Then another moved square appears. It will continue till all moved squares are in the right place. Each new square can change its color. It is carried out in the following sequence: red, green, blue, and, again, red. When the moved square bumps into the square of the same color, they are drawn to each other, and if the squares are of different colors – the moved square is pushed off by one square. If the moved square passes by the square of the same color on the game board, it will be drawn to it.
The game doesn’t comprise prepared levels; the special algorithm locates the circles on the game board that makes the game endlessly challenging. The number of circles, created by the algorithm, vary from nine to twenty nine.
