Diamond Thirteen
Diamond Thirteen is an add to 13 patience card game that plays in the browser on phones, tablets and computers, for one player. It has a daily challenge, the same for everyone that day.
A patience game where 25 cards stand in a diamond and pairs that add up to 13 are taken away. A card is free once two of the cards touching its corners are gone, kings go on their own, and the other 27 cards come one at a time onto two holding piles of your choice. A solver checks every deal before it is dealt, so each one can be cleared.
How to play
- Tap the next card, then pile A or B to keep it there for later
- Pick two bright cards that add up to 13. Ace is 1, jack 11, queen 12
- A king makes 13 on its own: tap it to clear it
- A card lights up once two cards touching it are gone
- Clear all 25 diamond cards to win. Undo and Hint are free
The game shows these steps as you play, the first time.

Tips
- Start at the four tips, since they are the only free cards at the deal, and clearing one frees the cards beside it.
- Keep the two holding piles for different needs, so a card you will want soon never ends up buried under one you cannot pair.
- Before you put the next card on a pile, look for its partner: a 9 with a free 4 makes 13 and clears both.
Which cards make 13 in Diamond Thirteen?
An ace counts 1, a jack 11 and a queen 12, so the pairs are ace and queen, two and jack, three and ten, four and nine, five and eight, and six and seven. A king is worth 13 on its own and goes with one tap.
Can every deal be cleared?
Yes. Before a deal is shown, a solver plays it with the whole deck in view and keeps it only once it has cleared all 25 diamond cards. Undo is free, and Hint uses the same solver to show a move from a winning line.
