Download WBridge, the computer bridge champion in 2005, 2007, and 2008, and experience the state of the art in computer bridge. Like Ginsberg’s Intelligent Bridge and its successor Jack Bridge, WBridge5 simulates many layouts consistent with the bidding and play up to the current trick, performs double dummy analysis on those layouts, and chooses the best percentage play. If the decision is close, it will simulate even more layouts, “thinking” harder, just like a human. Since the application is simply an executable and two help files (English and French), you can place them on a memory stick and always have them available without the need to install anything.	Download Bridgify for double dummy analysis. Walk through any hand trick by trick and see the best card(s) to play from each hand at each trick given the plays made previously. This program has a great simple, clean, and intuitive interface. Hands can be entered manually or loaded from PBN files. Since the application is just an executable and a help file, you can place them on a memory stick and always have them available without the need to install anything.	Download Lead Solver. Feeds the output of Thomas Andrews’ Deal bridge hand generator (or similar), through Bo Haglund’s fast double dummy analyzer and tallies up how well each card does when led at matchpoints or IMPs. Runs on Windows (DOS), Mac OS X, and Linux/Unix.
Download Bridge Solver, John Goacher’s double dummy solver for Android. Browse to a PBN file on a web page and go. There is also a Windows version (requires Java 1.8).	Download Bridge CCAnalyzer, Lars Kappel Hansen’s card combination (CC) analyzer for Android. There is also a online version.	Download Big Deal (Original DOS version) or Bigger Deal (Windows), a program to generate very random bridge hands. Obtains entropy from keystrokes or mouse clicks, can generate all of the ~5.4 × 1028 possible bridge hands, and uses cryptographic hashing of the PRNG sequence to prevent prediction of hands based on hands already seen in a set.
Download Round Timer, Rich Waugh’s full screen round timer, instead of paying hundreds of dollars for a custom built hardware timer that uses £10 of 1980s electronics.	Download KGB Batch Converter, Kaj G Backas’ bridge batch file converter. Ever needed to convert a DUP file to PBN format or handle something obscure like old Duplimate (BRI) format? This is the program for you. 28 formats are supported.
