Pyramid
Family: Adding / Sequential Removal
Pair up two cards that add to 13 to remove them.
Pyramid deals 28 cards in a triangular (pyramid) shape, and you remove pairs of cards whose values add up to 13. A King is 13, so it's removed on its own, while you pair A+Q, 2+J, 3+10, and so on.
Only uncovered cards (with no card below them) can be selected, so the order in which you clear pairs matters. Turn cards from the stock to supply more pairs.
It's short and casual but easy to get stuck in — a game that uses your sense of arithmetic.
