Show HN: Code Royale – Play and learn poker with Claude Code (skill)

2 points

3 months ago

I built a Claude Code skill that turns your terminal into a poker table. You play No-Limit Texas Hold'em against three AI opponents, each running as a separate Claude subagent with its own personality and hidden cards. The main agent acts as dealer, manages the game state, and optionally coaches you.

The coaching side has three modes: no help at all, real-time hints before each decision, or post-hand analysis only.

Fair warning: Claude naturally takes every hand to the extreme. Expect more pocket aces and dramatic river cards than any real table would produce.

   Coach's whisper: You flopped top pair with a king kicker — a very strong hand here. Jordan was the pre-flop raiser and is c-betting into you, which is standard. Calling is solid to
  keep the pot manageable. You could also raise to ~140 for value and protection, but calling in position and letting Jordan keep betting is a perfectly good line.

Something to do in your second terminal while Claude does your work in the first.
