How to Play Gin

Each player holds 10 cards. On your turn: draw one card (from the face-down stock or the face-up discard), then discard one card back.

Build melds:

• Runs — 3+ cards in sequence, same suit (4♥ 5♥ 6♥). Ace is low.
• Sets — 3 or 4 cards of the same rank (7♠ 7♥ 7♣).

Deadwood = unmelded cards (A=1, faces=10). When your deadwood is 10 or less you may KNOCK to end the round.

• GIN — 0 deadwood: +25 bonus, opponent can't lay off.
• Knock — opponent lays off deadwood onto your melds; you score the difference.
• Undercut — if the opponent ties or beats your deadwood, they score the difference +25.

First to the target score wins the game. Meanwhile every hand mines the rig — a rare verified Block-Found pays the real-crypto BLOCK REWARD.
