Darts scoring maths as an API, computed locally and deterministically — the X01 checkout and average numbers a darts player, league or scoring app runs on. The checkout endpoint solves a remaining score with an exact full-board search: whether it can be finished, the minimum number of darts and one valid combination that ends on a double or the bull — 170 finishes T20 T20 Bull (the highest possible three-dart checkout), 100 is T20 D20, 40 is simply D20, while 1 cannot be finished (the last dart must be a double, minimum 2) and the bogey numbers 169, 168, 166, 165, 163, 162 and 159 cannot be checked out in three darts at all. The average endpoint computes the three-dart average — total score ÷ darts × 3 — so 501 in 15 darts is a 100.2 average; a 100-plus average is strong play. Everything is computed locally and deterministically, so it is instant and private. Ideal for darts, league-scoring, pub-game and sports app developers, checkout-assistant and practice tools, and darts education. Pure local computation — no key, no third-party service, instant. Standard X01 rules; legs end on a double or the bull. Live, nothing stored. 2 compute endpoints. An exact scoring aid for the standard 20-segment board.

Farkle Score API
Farkle dice-scoring maths as an API, computed locally and deterministically — the points a Farkle (Zilch, Ten Thousand) scoring app tallies a roll by. The score endpoint takes up to six dice and returns the value by the common ruleset: a single 1 is 100 and a single 5 is 50; three of a kind scores the face times 100 (three 1s being the exception at 1000); four, five and six of a kind are 1000, 2000 and 3000; a 1-to-6 straight or three pairs is 1500; and two triplets is 2500 — so 1-1-1-5-5-5 scores 2500 as two triplets rather than 1100, a 1-2-3-4-5-6 straight is 1500, and 6-6-6-2-3 is 600 with the 2 and 3 dead. It flags a farkle when nothing scores (you lose the turn’s points) and tells you whether every die counted — a hot dice that lets you roll all six again. Rulesets vary, so it scores the widely-used set and says so. Everything is computed locally and deterministically, so it is instant and private. Ideal for dice-game, party-game and scoring app developers, score-helper and game-night tools, and board-game-companion software. Pure local computation — no key, no third-party service, instant. Scores a roll; it does not roll the dice. Live, nothing stored. 1 compute endpoint.

Cribbage Score API
Cribbage hand-scoring maths as an API, computed locally and deterministically — the count a cribbage player, app or league tallies a hand by. The score endpoint takes the four-card hand and the starter (cut) card and returns the full breakdown by the rules: every distinct combination of cards summing to fifteen scores 2, each pair scores 2 (so three of a kind is 6 and four is 12), each run of three or more consecutive cards scores its length — counting the duplicate runs that pairs create — a four-card flush in the hand is 4 (five with the starter is 5, and the crib only scores a five-card flush), and his nobs, a Jack in hand matching the starter’s suit, is 1. It correctly scores the famous best hand, J-5-5-5 with a fifth 5 cut, at the maximum 29. The count endpoint tallies just fifteens, pairs and runs for any one to eight cards — useful for checking part of a hand or the pegging pile. Everything is computed locally and deterministically, so it is instant and private. Ideal for cribbage, card-game, board-game-companion and scoring app developers, score-verification and teaching tools, and game software. Pure local computation — no key, no third-party service, instant. Cards as rank+suit (5H, TD, JS). Live, nothing stored. 2 compute endpoints.

Yahtzee Score API
Yahtzee scoring maths as an API, computed locally and deterministically — the category scores and totals a dice-game scoring app runs on. (It scores a given roll; it does not roll the dice.) The score endpoint takes five dice and returns the value of every one of the thirteen boxes at once: the upper boxes (ones through sixes) score the sum of that number, three- and four-of-a-kind and chance score all five dice, a full house is 25, a small straight (four in a row) 30, a large straight (five in a row) 40 and a Yahtzee (five of a kind) 50 — so 3-3-3-5-6 is worth 20 in three-of-a-kind, 4-4-4-5-5 is a 25-point full house, and it flags the highest-scoring box for you. The total endpoint adds up a finished card: the 35-point upper-section bonus when the upper boxes reach 63 (and how many points you still need for it), plus 100 for each extra Yahtzee, to give the grand total. Everything is computed locally and deterministically, so it is instant and private. Ideal for dice-game, board-game-companion, family-game and scorekeeping app developers, score-sheet and tournament tools, and game software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 compute endpoints. For random rolls use a dice API.

Tennis Score API
Tennis scoring maths as an API, computed locally and deterministically — the game, set and match logic a scoring app, umpire tool or tennis league runs on. The game endpoint plays a game from a sequence of who won each point and returns the proper tennis score: points run 0, 15, 30, 40 and then game, but at 40-40 it is Deuce and a player must lead by two — Advantage, then game — so a,a,a,a is 40-0 and a win, while three-all is Deuce; a tiebreak flag scores to seven by two instead (and keeps going at 7-7). The set endpoint reads a set from the games each player has won: a set is taken at six games with a two-game lead, 6-6 triggers a tiebreak that ends it 7-6, and 7-5 wins if a player pulls ahead first. The match endpoint settles the match from the sets won — best-of-three is decided by two sets, best-of-five by three — and tells you the winner the moment it is reached. Everything is computed locally and deterministically, so it is instant and private. Ideal for tennis, racket-sport, scoring, umpiring and league app developers, scoreboard and live-scoring tools, and club software. Pure local computation — no key, no third-party service, instant. Scoring logic, not analytics. Live, nothing stored. 3 compute endpoints.
