1) Teams, Seats, and Start Conditions

Each room uses 4 players in two teams: Team A and Team B. A round cannot start until teams are balanced 2v2. Before start, server logic normalizes player order to A-B-A-B so turn and deal flow stay deterministic.

2) Deal Flow (6 + 6 + Final)

The dealer controls deal progression. First pass gives 6 cards per player. Second pass gives another 6 per player. Final pass gives 9 cards to dealer and 7 to each other player.

During the final deal, one reveal card per player is broadcast for a short reveal window. After that timer ends, phase moves to Scart discard.

3) Scart Rule

In Scart phase, only dealer can act. Dealer must discard exactly 2 valid cards from hand. If card count is not exactly two or cards are invalid, the action is rejected.

When Scart is accepted, play phase starts and the first turn is the player to dealer's left.

4) Trick Play Core Rules

Players act strictly by turn order. Out-of-turn play is rejected. If a lead suit exists, you must follow that suit if your hand has that suit available (excluding Fool).

If you cannot follow lead suit and you still hold trumps, you must play a trump. Fool is always exempt and can be played under special handling.

5) Trick Winner Rule

If any trump is played, the highest trump wins the trick. Otherwise the highest card of the lead suit wins. The winner leads the next trick.

6) BUOB Trigger Conditions

BUOB is allowed only when a King is present in the current trick. The King suit must not have been led in earlier tricks in this round. BUOB can be called only once per trick.

7) BUOB Resolution Modes

• Forced Jack play: if target player has not played yet, that player is forced to play the Jack.
• Deferred swap: if target already played, swap resolves at trick finish according to server candidate priority.
• Self BUOB: if caller is target, swap is deferred and resolved at trick finish.

8) Fool (Narr) Debt Handling

Outside the final trick, Fool is returned to the owner's team pile. If Fool was in a lost trick, a debt state is created and later settled by transferring a payable non-Fool card from debtor team to creditor team when possible.

In the final trick, Fool remains in the won cards as a normal capture.

9) Scoring Formula

Card points are computed from captured cards: Kings and honor trumps/Fool are high value, face cards have descending values, and others default to 1. Then grouped deduction is applied by 4-card groups with remainder adjustment exactly as implemented in scoring logic.

10) Round End and Regame

At round end, Scart cards are added to the dealer team before score calculation. Match totals accumulate across rounds. Regame is only available after scoring and rotates dealer by +1 seat for the next round.
