Rules

  • Pick any remaining block. It and every block above and to its right are removed.
  • The bottom-left block (✕) is the corrupted cache. Whoever takes it loses the round.
  • Hover to preview what a move removes. The bot plays perfectly. Note: with the opening swap, a perfect responder can always win — a known property of this ruleset.
