Goal: Hold a 7, 8, and 9 (any suits) in your 3-card hand.
Your turn — flip a card, one action:
• Same rank → discard both, draw 1 replacement
• Adjacent ±1 → discard yours, take flipped card
• No match → goes to discard pile, turn passes
React: After each discard, opponent may take top discard or flip next.
Declare: Hold two of {7,8,9} + flipped is missing third + blocker is 3+ ranks away → discard blocker, take it, win. Flip only.
Block: Hold two of {7,8,9} when opponent declares → reveal hand, void their declare. No more reshuffles.
Tiebreaker: Deck exhausted → compare sum of your 789 cards. Higher sum wins. Tie → highest individual card wins.
