This popular game is now available in a computer game version! Play your cards (placing a chip on one of the corresponding card images on the board). The object of the game is to form numbers of rows of 5 chips (be it horizontally, vertically or diagonally) before the other players. The yellow and black cards fulfill a special role. If you play a yellow card, you may place a chip anywhere on the board (except of course on the wilds). If a black is played, you can remove an opposing player's chip from anywhere (except connected lines). Sequence: Sand Castle has 2 extra game modes: Story and Survival. Play Survival to collect as many SEQUENCEs as you can. Play Story to open full map of Sand Island and conquer Sand Castle.
