Bridge Solver
*NEW* - LOCKDOWN SOFTWARE
If you play bridge in BBO tournaments, you can now extract the results from BBO and upload them to your website or NBO, with full scorecard and traveller details, and hand records, using our new BBO Extractor software. See here

Bridge Solver Online is a free interactive bridge hand analyser utilising Bo Haglund's well known double dummy solver module. It can be integrated with websites or used standalone, and is usable from a web browser on any desktop or mobile device without installation. It can calculate makeable contracts and optimum contracts for any bridge hand, or the user can play hands in double dummy mode with card by card guidance to discover the lines of play that allow the makeable contracts to be achieved.

Alternatively, Bridge Solver is available as a free installable app for various platforms. A unique feature of the installable versions, compared to other double dummy solver apps, is the ability to detect and load hands directly from hand diagrams on bridge results pages, for a variety of supported formats. For a feature comparison of the various versions of Bridge Solver see here.

If you just want to use Bridge Solver Online (BSOL), and have a .PBN , .DLM , or bridge base online .LIN file, or wish to input a deal manually, you can access it by clicking on the button below. Alternatively, try it out on one of these sites that already utilise BSOL.

New:

Bridge Solver Chrome Extension now has an option to open tabs in a new window rather than in the existing window. Thanks are due to John Lambe for designing and implementing this functionality. This is particularly useful when using the extension in conjunction with a logged in BBO session, as it allows the windows to be viewed side by side subject to sufficient screen real estate. See the release notes for further details. 25th April 2020

See this video by John Dillon of Vero Beach Bridge Center for a demonstration of using Bridge Solver Chrome Extension with Bridge Base Online. 23rd April 2020

Bridge Solver Chrome Extension now has some additional features when used with Bridge Base Online - click here for details. Updated 9th April 2020

For a useful guide to using Bridge Solver Online to review hands played on Bridge Base Online see this document by Rees Mitchell of Vanderbilt Bridge Club. Rees has also produced this guide illustrating the use of Bridge Solver Online to play hands in double dummy mode with card by card guidance.

Bridge Solver Online is designed for easy integration with bridge club websites. The double dummy solver library is integrated into an executable CGI module hosted on a web server. The user interface is browser based and can run on any desktop, tablet, or mobile device that supports a modern browser. BSOL provides the same makeable contract and optimum contract calculation, and interactive double dummy play, that is available in the android app and Windows desktop versions.

BSOL has initially been integrated into BridgeWebs, which hosts websites for more than 1700 bridge clubs worldwide.

Gwynne Hughes (author and owner of BridgeWebs) has generously agreed that non-BridgeWebs sites may access BSOL on the BridgeWebs server free of charge, subject to approval. It is therefore a straightforward matter to integrate a hand replay function into results pages on other bridge club sites. This requires only the insertion of a link to a BSOL html page on the BridgeWebs server, together with a number of parameters defining the hand to be played, the dealer, vulnerability etc. For a list of clubs and websites using BSOL see here.

If you are a webmaster for a club website, or a provider of hosting software for bridge club websites, and are potentially interested in integrating Bridge Solver Online into your site(s), please contact me at the email address below:
