Bridge scoring is quite complex. It depends on the final contract and the number of tricks won by the declaring side.

The final score consists of "trick points" and a "contract bonus".

The trick points change according to the type of the contract and is counted in addition to the book (the first 6 tricks are not counted):

• "Minor suits" – ♣ and ♦ are worth 20 points for each trick.
• "Major suits" – ♥ and ♠ are worth 30 points for each trick. 
• In No-Trumps, the 7th trick counts for 40 points, and all higher tricks for 30 points.

The contract bonus depends on the level of the contract, the type of contract, and vulnerability (green = non-vulnerable, red = vulnerable):

• "Part-score" bonus – 50 points (all contracts lower than game)
• "Game" bonus – 300/500 points (3NT, 4♥/♠, 5♣/♦ and higher)
• "Small slam" bonus – 800/1,250 points (6♣/♦/♥/♠/NT)
• "Grand slam" bonus – 1,300/2,000 points (7♣/♦/♥/♠/NT)

The declaring side is penalized if they don't make the contract (the opponents receive points). The penalty for not making the contract is -50/-100 points for each trick that is missing to make the contract.

The rewards and penalties can be further multiplied if the defenders decide to "double" the contract. When the defenders double the contract, the declaring side can "redouble" to increase the stakes even more.
