Game Rules — 游戏规则
Golden Bull 牛牛 is a Dealer-vs-3-Areas game. Every round deals 20 unique cards from a freshly, securely shuffled 52-card deck: 5 to the Dealer, and 5 each to Area 1, Area 2, and Area 3. You may bet on one, two, or all three areas, each compared independently against the Dealer.
Card Values (for Bull calculation)
- Ace = 1
- Cards 2–9 = face value
- 10, Jack, Queen, King = 10
Card Ranks (for tie-breaks)
K > Q > J > 10 > 9 > 8 > 7 > 6 > 5 > 4 > 3 > 2 > A
Default suit priority: Spades > Hearts > Clubs > Diamonds (admin-configurable).
How a Bull Hand Is Calculated
- Every possible 3-card combination is checked for a total divisible by 10.
- The remaining two cards' total, last digit only, is your Bull value (0–9).
- If that remaining total is also divisible by 10, it's Bull Bull (牛牛).
- If no 3-card combination sums to a multiple of 10, the hand is No Bull (无牛).

How Winning & Losing Works
Current mode: Authentic
If your area wins, profit = bet × your area's hand multiplier. If the Dealer wins, your loss = bet × the Dealer's hand multiplier — meaning a loss against a strong Dealer hand (e.g. Bomb Bull ×4) can exceed your original bet. A push returns your stake exactly.
Because a loss can exceed your bet, we reserve your maximum possible liability (bet × the highest enabled multiplier) from your available balance the moment you confirm a bet. Unused reserved credits are always returned after settlement.
Exact-Tie Rule
When an area's hand is completely identical to the Dealer's (same category, same Bull value, same highest card, same suit): currently configured as Dealer wins.
Fairness
All shuffling, dealing, hand evaluation, and payout calculations happen exclusively on the server using cryptographically secure randomness. Cards are never sent to your browser before their reveal phase, and nothing in the browser can influence a result.
