A gap can be filled by a card which is of same suit as card on the left and one rank higher, or same suit as card on the right and one rank lower. Gap to right of Queen can be filled with any Ace. Gap to left of Ace can not be filled. All cells in the grid are counted as one row so the cells in the grid run from left to right, top to bottom. Last card in the grid (6th row) can be connected to first card in the grid (1st row) to complete a sequence. Arrange all 48 cards in four suit sequences from Ace to Queen to win. The gaps do not matter in the sequence. Features: Save game state to play later; Unlimited undo; Game play statistics.
