The Problem
Bridge is one of the hardest games to improve at, because you almost never learn whether your decisions were right. A sound bid can lose and a poor lead can win, so the result hides the decision behind it. Books hand you theory with no practice, and real play gives practice with no answers. On BridgeDummy every bid and every lead is graded against an objective right answer, so you see which choices were sound and which just got lucky.
Our Origins
BridgeDummy was created by Nir Khutorsky, a software engineer and competitive bridge player: a world youth champion (under-16) and world runner-up at under-21 and under-26 level, a member of the Israel Open Bridge Team, and a bronze medalist at the 2026 European National Teams Championships. He saw firsthand how the gap between theory and practice holds players back, and he built BridgeDummy to train the lead and bidding decisions that cost players boards.
Our Philosophy
Players improve fastest by making real decisions repeatedly. Every puzzle is a genuine bridge scenario with multiple reasonable options, graded by double-dummy analysis. This builds pattern recognition and judgment that goes well beyond convention knowledge.
Our Mission
Every practice session should put a real decision in front of you, grade it against optimal play the moment you commit, and show you how you improve over time.
