Your goal is to place the shapes of color blocks on the game field and create groups of three or more blocks of the same color that will be deleted and make space for new blocks. The more blocks you remove at once, the more game points you will get. At the beginning of the game all the shapes consist of blocks of the same color, but with score growth will appear blocks containing another blocks of a different color. After the removal of such blocks, the internal blocks will increase and occupy the places of the removed blocks. Did you make the wrong move? Use the undo button to undo your last move. Your game is automatically saved when you exit, so you can interrupt at any time and continue the game from the same place. Your goal is to survive as long as possible and score as many points as possible.
