Domino
- Public tables for 2, 3 and 4 seats, including the four-player free-for-all
  (domino_table_join/leave, domino_merge_state); bot matches pay real coins.
- The Egyptian lock rule: a blocked game is scored, the opponent no longer
  draws the boneyard.

Backgammon (tawla)
- 31: the first runner must reach the home board before the rest may move.
- New board colours so the white checkers read clearly (--bg-* tokens,
  DESIGN.md, branding admin).

Matchmaking
- After 60 s with no opponent, a procedurally generated player-like bot takes
  the seat (ghost_profiles); unrated, paid once, 90 s anti-farm floor.

Chess and ludo
- Premoves merged; draw on flag when the side left cannot mate; bot payout
  guard; ludo seat guard and rules fixes.

Social and sessions
- Chat: the sender on the right, the other person on the left; a thread whose
  first load failed keeps retrying instead of going silent; creating a group
  survives a dropped answer without making a second group.
- Group chat messages readable by members only (RLS).
- A slow auth service no longer signs players out: the server answers 503
  instead of a cached 401, refresh only ends a session the server refused,
  and realtime channels receive the refreshed token.
- complete_match raises levels with XP.
