The aim is to fill the board with your tiles, the yellow ones. You play against the computer. Some tiles are already placed at the beginning. To add another one of yours, there must be a red tile between one former yellow tile and the one you are adding. The red tile so “captured” becomes yellow. Then, it’s the computer’s turn, and so on. You can also choose to pass your turn or be forced to. Click on the small hand to get the next game. The yellow cylinder fills, with your victories, the red one, with the computer's victories. The one who reaches the top the first wins.
