About
WBridge5 is a highly acclaimed, free contract bridge software for Windows, developed by an independent author and backed by a dedicated user community. The program features a sophisticated AI engine that has competed successfully at the World Computer Bridge Championships, finishing as a finalist or winner multiple times since 2000 — most recently taking the title in 2016. Designed for bridge enthusiasts of all skill levels, WBridge5 lets players practice and improve their game against a strong computer opponent in Duplicate mode. The built-in deal generator makes it easy to create and replay hands, while full support for the PBN (Portable Bridge Notation) file format allows users to import and replay hands from major international tournaments and compare their decisions against world-class players. The program also includes an open-card problem solver — ideal for analyzing specific bridge situations — and a personal library for storing and annotating commented deals. For those who prefer human competition, WBridge5 integrates with the separately downloadable Bridge Moniteur for local network play. Lightweight and compatible with Windows 2000 through Windows 8, WBridge5 requires minimal disk space or memory. An active user mailing list provides community support, bug reports, and discussion of strategy. Whether you are a beginner looking to learn contract bridge or an advanced player seeking a tough AI sparring partner, WBridge5 is a comprehensive and completely free solution.
