If you have any problems or queries concerning the Free Bet Calculator that are not addressed in the Known Issues section below, then you may find the answer in the Betting Glossary or Help pages, but if not you can either:-

If you are having a problem with the Free Bet Calculator website, then if possible please send details of the operating system (e.g. Windows 10), and browser that you are using (e.g. Google Chrome), along with a description of the problem you have encountered. This should allow the problem to be reproduced, and fixed where possible.

Known Issues

  1. Windows XP, Vista & Internet Explorer.

    The entire website is currently compatible with Internet Explorer 8 and above. The Old Bet Calculators are also compatible with Internet Explorer 6 and 7, but Microsoft no longer supports anything earlier than Internet Explorer 11, on any of their desktop operating systems.

    Microsoft has also ended support for Windows XP & Vista, and Google has dropped support for their Chrome browser on both of these operating systems. Mozilla has reduced support for their Firefox browser on Windows XP & Vista, and has announced that they will end support altogether in June 2018.

    If your operating system or browser is no longer supported, and as a consequence doesn’t receive security updates, then known defects that are being actively exploited won’t be fixed. This exposes you to a number of serious risks, so for important information on how to protect yourself and your computer, please visit the Get Safe Online website for free expert advice. The section on Protecting Your Computer contains many useful articles, on topics such as how to Update Your Browser, and Replacing Windows XP (which applies equally to Windows Vista).

    Since it isn’t viable for the Free Bet Calculator to continue supporting operating systems and browsers that are no longer supported by their developers, these unsupported platforms are no longer being taken into consideration when developing new features for the website.

  2. Performance issues on older Android devices.

    The best solution is to download the free Sports Bet Calculator app on Google Play. This native app is specifically designed for Android devices, so the performance issues affecting browser-based applications are avoided, leading to a significantly better user experience on older versions of Android.

Release Notes

1st November 2017

This release consists of a major upgrade to the underpinnings of the Free Bet Calculator website, enabling a significant number of improvements in performance and efficiency when using a modern browser. As a consequence, the level of support for legacy browsers has been reduced, so for example, animated visual effects may appear less smooth when using Internet Explorer 8 (note: this feature can be disabled via the Settings if you prefer).

There may be compatibility issues if using an old version of a less popular browser, since these can’t be tested, but a range of legacy browsers (including Internet Explorer 8, Firefox 10 and Opera 12), have been tested successfully. Since these old browsers are no longer supported by their developers, testing only takes place following major system upgrades, in order to verify the browser compatibility details listed on the Accessibility page. Any issues identified during this phase of testing won’t be fixed, but the list of compatible browsers will be updated.

The Old Bet Calculators remain unchanged, and are still used by approximately 2.5% of visitors, but anyone relying on an old browser that doesn’t receive security updates, should seriously consider upgrading.
