GIN RUMMY

The classic two-handed rummy. Phase 1 solo vs an AI bot. Draw a card from the stock or take the top of the discard, then discard one. Build melds — three or more same rank, or three or more consecutive cards of the same suit (Ace low only, no Q-K-A wrap). Knock the moment your deadwood drops to 10 or less; Gin (zero deadwood) earns a 25-point bonus. If your opponent's deadwood is ≤ yours, they undercut you for +25 plus the gap.
