Read full descriptionHide full description
The game is based on the principle of the puzzle "15". Moving the chips you need to collect them in order. The game ends when all the chips in all layers will be in ascending order, starting with the upper left corner of each layer. The field sizes are initially available in width and height from 3 to 5 and the number of layers 1. With a width and height of 3, you can set the number of layers 2. Control: When you touch and further move one finger to the screen area outside the chip field, you can twist the chip field. Chips move by touching them with one finger and moving in the desired direction. You can move only those chips that do not have a neighbor in one of the directions. You can shift the layers. To do this, it is necessary to simultaneously touch two chips of one layer with two fingers and slides in the desired direction until the layer is fixed. Similarly, the layer returns to its place. Important! In the moved layer, you can not move chips! You can extend the application's capabilities with the built-in purchases: - "All dimensions" - limits on the size of the field are removed.
