Dominoes Scoring API
Dominoes scoring as an API, computed locally and deterministically and exactly — the points behind a game of bones, whether you play Block, Draw or All Fives. The score endpoint gives the winner's points at the end of a hand: when a player dominoes or the game blocks, the winner takes the total pip count left in the opponents' hands — pass each opponent's remaining pips and it sums them, optionally rounding to the nearest five as many house rules do, so 12, 8 and 23 left on the table is 43, or 45 rounded. The fives endpoint scores All Fives (Muggins): a play scores whenever the open ends of the layout add up to a multiple of five, and you score that sum — open ends of 3 and 2 make 5 for five points, 5-5-5 across a spinner makes 15, while a 6 scores nothing. The set endpoint gives the statistics of a double-N set: a double-six has (6+1)(6+2)/2 = 28 tiles and 168 total pips, a double-nine has 55 tiles and 495 pips, with the heaviest tile and its pip value. Everything is computed locally and deterministically, so it is instant and exact. Ideal for dominoes apps, online and club scorekeepers, game-night and tournament tools, and learning aids. Pure local computation — no key, no third-party service, instant. Exact integer maths. Live, nothing stored. 3 compute endpoints. Standard Western dominoes; regional variants score differently.
