To discard all the cards in pairs.Rules
- 25 piles
arranged in a 5x5 square - discard pairs of cards that add to 14, if they are in the same row or column. For example, a King and an Ace, a Queen and a 2, or an 8 and a 6. To remove a pair, pick up one card and drop it on the other. Spaces are filled automatically from the stock. At the start of the game 1 card is dealt to each pile.
- Fill cell
- when all available pairs have been discarded and the stock is empty, clicking the fill cell fills spaces from left to right in the top row with cards taken from right to left from the bottom row.
