Dominoes: All Fives, one against three, first to 250

Four at the table with a double-six set: five tiles each and a boneyard,
the first double a spinner that opens four ways, and every multiple of
five on the ends scored as it falls. Three computer players who count
what the table can see and never a hand, and talk the whole time.

+## What this is
+
+An independent implementation of All Fives, the domino game, written from
+scratch in TypeScript in 2026: one human against three computer players.
+
+## The game
+
+Dominoes is centuries old and belongs to everybody; so do All Fives and its
+spinner. The rules here follow the published descriptions at
+[pagat.com](https://www.pagat.com/domino/cross/all_fives.html), with the house
+rules stated on the landing page. Rules are ideas, not expression, and nothing
+of anybody's text is reproduced.
+
+## What is ours
+
+Everything else: the rules engine, the layout, the bots and their reasoning,
+the table talk, the interface, the music and every other sound effect, and
+every word on screen. Every tile is drawn in code, and every sound but one is
+synthesized in code; there are no image files.
+
+## The shuffle
+
+The one recorded sound is the shuffle, in `src/audio/shuffle.mp3`: the first
+3.6 seconds of **"Shuffling Dominos" by RobertWulfman** on Freesound,
+
+- <https://freesound.org/people/RobertWulfman/sounds/220839/>, CC0 1.0
+  (public domain dedication)
+
+trimmed, leveled and faded at both ends for this game. CC0 asks for nothing,
+not even credit. It is credited anyway, because it was the only shuffle that
+sounded like a shuffle. If the file cannot be loaded, the game falls back to a
+synthesized one.
