  3. 3Players auction by bidding a level and strain, or passing.
  4. 4A later bid must outrank the current highest bid.
  5. 5Three passes after a bid end the auction and set the final contract.
  6. 6The declaring side must win six book tricks plus the contract level.
  7. 7Players must follow the led suit if possible.
  8. 8In a suit contract, trump cards beat all non-trump cards.

  10. 10The hand ends after 13 tricks, then the contract is scored as made or defeated.

Bridge rules, bidding, declarer play, and online practice

Bridge is a partnership trick-taking game where the auction decides the goal before the cards are played. Each bid names a level and a strain, such as 1NT, 2 hearts, or 4 spades. The final contract says how many tricks the declaring side must take and which suit, if any, is trump.

This online Bridge game focuses on a readable single-hand practice format. You sit South with North as your AI partner. West and East defend. The table supports contract bids from 1 club through 7 notrump, suit and notrump play, follow-suit rules, declarer and dummy roles, trick scoring, and quick restarts.

The auction is a language, and the vocabulary is smaller than it looks: seven levels times five strains gives exactly 35 possible contract bids, always climbing from 1 club at the bottom to 7 notrump at the top. Each bid must outrank the last, three passes close the auction, and the surviving bid becomes a binding promise — six book tricks plus the level named. Bidding well starts with counting high-card points: aces are four, kings three, queens two, jacks one, and the whole deck holds 40, so roughly 25 combined partnership points is the classic threshold for attempting a game-level contract.

Matches here follow a four-deal Chicago rhythm. Hand scores accumulate across exactly four deals, and the partnership with the higher total after the fourth deal wins the match. That structure keeps sessions short and stakes clear: a failed 4-spade contract on deal two is not a disaster, it is a deficit you can erase by defending well on deal three. Scoring is streamlined — trick points for made contracts and overtricks, undertrick points to the defenders — without doubles or vulnerability to juggle while you are learning.

Card play rewards planning before the first card leaves your hand. As declarer you count sure winners, decide which suit to establish, and choose when to pull trump; as a defender you track which suits opponents cannot follow and keep honors positioned behind declarer's strength. Those habits transfer directly to club and tournament play later, and the strategy guide walks through each of them with concrete holdings.

Contract bridge has a reputation as the hardest classic card game to start — mostly because it normally takes four people and a patient teacher. Playing online removes that barrier. Your AI partner bids and plays immediately, so you can learn one hand at a time with no club, no scheduled foursome, and nobody waiting on you. Start with the rules page for setup and legal plays, use the bidding guide to make sense of the auction, and when you are curious what a made or defeated contract is worth at a duplicate table, the scoring calculator breaks down any result number by number.

How Bridge bidding works

A bid combines a level from one to seven with a strain: clubs, diamonds, hearts, spades, or notrump. Higher levels promise more tricks. Higher strains outrank lower strains at the same level.

  • 1 club is the lowest contract bid.
  • 1 notrump outranks 1 spade, 1 heart, 1 diamond, and 1 club.
  • 7 notrump is the highest contract bid.

Playing the contract

After the auction, the player after declarer leads the first trick. Players must follow suit when possible. If the contract has a trump suit, trump cards beat cards from other suits.

Why dummy matters

Declarer plans using two partnership hands. Even in this AI-assisted version, dummy is part of the contract puzzle: count sure winners, protect entries, and decide when to draw trump.

What a contract is worth

In full duplicate scoring, minor-suit tricks score 20, major-suit tricks 30, and notrump 40 for the first plus 30 after — which is why 3NT, 4 hearts, and 5 clubs are the shortest routes to a game bonus. The scoring calculator on this site turns any contract and result into a complete breakdown.

Bridge FAQ

What is a contract in Bridge?
The last bid standing after three consecutive passes. A contract of 4 hearts, for example, commits the declaring side to ten tricks — the six-trick book plus the level — with hearts as trump.
How does the auction work?
Each bid names a level and a strain and must outrank the one before it. Strains climb clubs, diamonds, hearts, spades, notrump, so 1NT beats 1 spade, and the ladder tops out at 7NT.
Who is declarer, and what is dummy?
Declarer is the player who first named the winning strain for their side. Their partner becomes dummy. In traditional bridge, dummy spreads all 13 cards face up after the opening lead so declarer can plan with both hands; in this online version the dummy seat stays hidden and plays its own cards automatically.
How many tricks does 3NT need?
Nine — the fixed book of six plus the contract level of three, won with no trump suit to lean on.
Does this version include doubles and vulnerability?
Not yet. This edition keeps the focus on the auction ladder and card play; doubles, redoubles, and duplicate-style vulnerability are candidates for later layers.
Is this a good way to learn Bridge?
It removes the classic obstacle: assembling four patient people. The AI seats bid and respond instantly, so you can replay hand after hand with the bidding guide open until the auction starts to click.
