DeclarerBattle is a 2-player competitive bridge card-play game. Players are Red and Blue. The dealer alternates and is always the declarer. The other player defends with an AI partner. Scoring is individual.

Scoring
DeclarerBattle uses simplified scoring to keep contests balanced regardless of contract level:
Contract made: 300 points to declarer's side
Each overtrick: +30 to declarer's side
Each undertrick: +50 to the defence
Difficulty
Each player selects their own difficulty in the lobby before joining:
EasyMedHard
Higher difficulty means harder contracts (more tricks needed). Players can choose different levels, creating a handicap system — experienced players on Hard, newcomers on Easy.
Game Setup
One player creates a table and shares the room code. The other joins using the code. Players choose Red or Blue. The creator (admin) controls dealing and can close the table. Two players are needed to start.
