Rules in brief
- Deal. All 52 cards are dealt, 13 to each player. Partners sit opposite each other.
- Auction. Starting with the dealer and going clockwise, each player passes, bids, doubles or redoubles. A bid names a number of tricks over six (1 to 7) and a strain: ♣, ♦, ♥, ♠ or No Trump. Every bid must be higher than the last. A bid followed by three passes ends the auction; if all four pass, the cards are dealt again.
- Declarer and dummy. The player of the winning side who first named the strain is declarer. The player on declarer’s left leads; then declarer’s partner, the dummy, lays the hand face up and declarer plays both hands.
- Play. Follow suit if you can; otherwise play any card. The highest trump, or else the highest card of the suit led, wins the trick, and the winner leads to the next one.
- Scoring. Declarer’s side needs 6 + the bid level tricks. Contract points, overtricks, undertricks, doubles and slam bonuses follow standard bridge scoring. Vulnerability rotates as in a Chicago: nobody on deal 1, the dealer’s side on deals 2 and 3, both sides on deal 4.
- Duplicate or Chicago. When you create a table, choose duplicate‑style scoring (each deal on its own: 50 for a part‑score, 300 or 500 for a game) or traditional Chicago (part‑scores add up; reaching 100 earns the game bonus and wipes out both sides’ part‑scores; a part‑score made on deal 4 that does not complete a game gets +100).

Frequently asked questions
What bidding system do the bots use?
The bots bid a simplified 2/1 game‑forcing system in the GIB/BBO style. The strongest bots plan the play with double‑dummy analysis of sample deals built only from what they can see.
Who plays the dummy?
Declarer. Once the dummy is face up, declarer chooses the cards from both hands; the dummy’s player only watches.
What is vulnerability?
A vulnerable side scores more for games and slams but loses more when it goes down. In a 4‑deal Chicago it changes from deal to deal.
Can I play Bridge online with friends?
Yes. Open a private table on TrickHall, share the link, and play together from your phones. Bots can fill empty seats.
