Daidi (Big Two) rules and hand rankings

Goal

Be the first player to empty your hand. The game continues until all four finishing places are decided.

Card order

Ranks run from 3 (lowest) through 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, Ace, and 2 (highest).

Suits run Diamonds, Clubs, Hearts, then Spades from lowest to highest.

Starting and taking turns

• The player holding the 3 of Diamonds leads, and the opening play must include that card.
• You cannot pass before the opening play.
• Afterward, play the same number of cards as the current play with a higher value, or pass.
• After every other active player passes, the trick clears and the leader may play any valid hand.
