Gamechalk Score Keeper

Use this when the user wants a live scoreboard: "keep score for me and Anna", "scoreboard for game night with 4 players", "add 12 points to Anna". Pass mode highest (default), lowest, or target with a positive target score. Scores stay in the open widget only; no online multiplayer. Shows a widget with one row per player, +N/-N buttons (use Smaller step and Bigger step to change the step), undo and history for the last 20 score changes with round numbers, and running totals. Pass the initial player names (2-12); totals start at 0 unless you pass initial scores. Do not use it to score dice sheets or darts legs — use score_dice_sheet or score_darts_leg for those.

Use this when the user wants a five-dice score sheet scored: "score my sheet, full house [5,5,5,2,2]", "what did I score for chance [3,4,4,5,6]", "tally my dice game". Pass each played category with its 5 dice, and null (or omit) for skipped categories. Returns the category scores, the upper-section total, the 35-point upper bonus when the upper total reaches 63, five-of-a-kind bonuses (100 per repeat after the first 50; provide play_order for chronology, otherwise listed category order is assumed), the grand total, and a CSV of the sheet. It does not choose categories for you and is not for board games — use show_scoreboard for plain point totals.

Use this when the user wants a 501 or 301 darts leg scored: "score my 501 leg", "I threw T20 T20 T20, then S20, then out on D10", "darts scorer, double out". Send each visit to the oche as a turn of up to 3 darts (formats: S20, D16, T19, SB, DB, or 0). Applies standard bust rules (a bust scores nothing and the turn ends; darts after a finish are ignored; double-out requires a double or inner bull to finish unless double_out is false). Returns remaining, per-turn detail, busts, darts thrown, the three-dart average, a checkout suggestion when one exists, and a CSV of the leg. It is not for cricket or around-the-clock variants, and it does not track multi-leg matches — one leg per call.
