Key facts:
- Chess960: the back-rank pieces start in one of 960 arrangements; castling
  always ends on the classical squares (g1/c1 for White).
- Every starting position has a page: https://ch960.com/sp/ (0-959; /sp/518 is
  the classical chess setup).
- Play in the browser, no install, no account: a friend by link or QR code
  https://ch960.com/friend (the link /c/{id} also lets others watch the game
  live); the computer at a chosen level https://ch960.com/play; an endless
  puzzle feed https://ch960.com/flow. A finished game stays at /g/{id} for
  30 days with a move-by-move engine review.
  Rated games and arenas are in the Android app.
- Undo Chess, a rule set by Roman Morozov (the author of CH960): in a game with
  a friend each player may get 1-3 take-back tokens, and taking a move back
  hands the token to the opponent. Rules: https://ch960.com/undo-chess ; core
