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.
Bridge Solver Chrome Extension adds the ability to capture deals directly from hand diagrams on various bridge results websites, and launch the hands in Bridge Solver Online.
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.
Bridge Solver Chrome Extension can now acquire hands from results pages on the RealBridge online system.

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.
Integration With Club Websites
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 been integrated into BridgeWebs, which hosts websites for more than 2000 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 the major 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 at the bottom of this page.
Bridge Solver is also available as a free installable app for Android and Windows. As with the Bridge Solver Chrome extension, the installable versions have the ability to detect and load hands directly from hand diagrams on bridge results pages, for a variety of supported formats. However, Bridge Solver Online, together with the Bridge Solver Chrome extension, now surpasses the functionality of the installable apps, with the exception of the ability of the Windows version to read hand diagrams from PDF files. Due to the amount of effort required to support multiple versions it is unlikely that the functionality of the Android and Windows standalone versions will be extended in future. For a feature comparison of the various versions of Bridge Solver see here.
