Gaps is a simple mechanical game with frequent fun twists.
The cards are dealt in four rows of 13. Then aces are removed.
The blank spaces left by the aces can be used to move cards to, as long as the card is the same suit as the one to the left, and one number higher. For instance, a jack of spades can be moved in a space to the right of a 10 of spades.
A blank space on the left side can be filled with any 2.
Note that nothing can be placed to the right of a king.
You can click on the deck button to the bottom left to pull in all cards except those already placed by order and suit. Then those cards and redealt randomly and aces removed again. You have 3 redeals in a standard game.
You win when all four rows features same-suited cards in order from 2 to king. The last space in each row should be empty.
