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.
Windows XP, Vista, 7, 8 & Internet Explorer.
The entire website is currently compatible with Internet Explorer 9 and above. The Old Bet Calculators are also compatible with Internet Explorer 6, 7 and 8, although Microsoft no longer supports anything earlier than Internet Explorer 11 on any of their operating systems.
Microsoft has also ended all support for Windows XP, Vista & 7, and no longer provides mainstream support for Windows 8. Google’s Chome browser, and Mozilla’s Firefox browser, are still supported on Windows 7 and later.
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 7 (which equally applies to Windows XP & 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.
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.
7th December 2020
This release addresses various legacy issues requiring workarounds, which are no longer necessary for newer browsers and operating systems, so are now applied conditionally. This should improve performance and responsiveness in a number of browsers, but particularly on iOS 9.3 and later.
Styling consistency has been improved on modern Firefox browsers, especially on Linux-based operating systems.
Numerous styling and layout adjustments have also been included, along with more general optimisations to further improve site performance.
28th September 2020
With the exception of the Old Bet Calculators, nobody has visited the website using Internet Explorer 8 for over 6 months, so support for this browser has finally been removed. This is primarily to simplify future development, but it will also reduce page load times. Any visitors still using Internet Explorer 8 are now automatically redirected to Old Bet Calculator (2010), so they can still calculate their bets, but won’t be able to access newer parts of the site.
This release also contains various minor bug fixes, accessibility improvements and styling tweaks, plus a range of optimisations that should further reduce page load & rendering times, particularly on slower mobile devices.
11th June 2020
This release contains some bug fixes and usability improvements.
The first bug fix addresses the incorrect positioning of tooltips related to the dead heat and joint favourite selection options. The second bug fix corrects the column navigation ‘overshoot’ when comparing bet types on the website’s tablet layout.
All sections of the Betting Glossary and Help pages are now permanently expanded, making it possible to browse the entire page without opening each section in turn. To minimise scrolling when searching for a particular item, new dropdown indexes allow you to skip directly to the relevant point on a page. A ‘floating’ Top button also enables a quick jump back to the top of the page.
14th August 2018
A minor release to fix an issue concerning the validation of bet details when using Microsoft’s Edge browser.
11th July 2018
This release consists of various framework upgrades, along with a minor bug fix, and the removal of the Facebook ‘Like’ button from the website.
The bug fix only concerns Microsoft Phone users, or anyone still using an old Android 4 browser. It resolves an issue that allowed a stake to be submitted to the bet calculator in an incorrect format, which would then get reported as an error indicating that “The minimum stake is 0.01”.
The Facebook Like button has been removed primarily due to privacy concerns, following Facebook’s admission that their Like button code is used to track non-users.
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.
25th September 2017
The Free Bet Calculator has been transferred to a new platform with even better performance, reliability and security, plus support for some of the latest web technologies that will be required for upcoming releases.
Support has also been improved for the pinning of web pages using the add to home screen / pin to start / pin tab functionality that is available on many devices, including those running iOS, Android, Windows 10 and OS X. For example, if you want to add the Lucky 15 Bet Calculator to the home screen of your device, the name of the shortcut now defaults to “Lucky 15”, instead of the full page title.
31st May 2017
A new optimised icon font has been introduced that is significantly smaller than the old one, and will reduce page load times. This font contains the icons used to highlight various interactive elements throughout the site, such as the main menu items and context-sensitive help.
Various other aspects of the website’s styling have also been improved, including the logo and various buttons.
In response to a user request, the Bookies Nightmare bet has been added to the Free Bet Calculator, and a dedicated Bookies Nightmare Bet Calculator has been added to the collection of Quick Bet Calculators. If you are not familiar with this bet and would like to know more, then there is a description in the Betting Glossary.
1st March 2017
This release consists of minor content updates, framework upgrades, and various tweaks to reduce page sizes and optimise system performance even further.
12th April 2016
The bet calculators will now work with Google Chrome’s built-in language translator. The layout of some elements may be affected where the translated text is longer than the original English text, particularly on devices with small screens, but this shouldn’t affect functionality. Any layout issues resulting from language translation can normally be mitigated, and often eliminated, by rotating mobile devices into their landscape orientation, or by maximising the browser when running on a PC.
The method used to display calculated amounts has been modified, so that very large theoretical returns are reported without any loss of
precision. Also, if the calculation of a ‘fantasy bet’ exceeds the system limit of 79 octillion (7.9 x 1028), a more
suitable error message now replaces the catch-all
The bug has been fixed that allowed the number of places associated with a dead heat, to become lower than the selection’s finishing position, when changing the status from Won to Placed. The number of places is now automatically increased to the minimum for a placed horse (i.e. 2), although the user may still need to change the dead heat details to reflect the actual number of places for a particular race. If the number of places really is lower than the selection’s finishing position, then the selection has of course lost, in which case a dead heat can’t apply.
10th March 2016
This release introduces the ability to compare the potential profit from the most popular types of bet using the new Compare Bet Types calculator, which is now available in the Quick Bet Calculators section of the website.
For example, you can enter the details of 4 selections, and calculate Singles, Doubles, Trebles, Accumulator, Yankee, Yap, Lucky 15 and Flag in a single operation. All of the calculated amounts are tabulated to allow a direct comparison between each bet type.
Alternatively, if you have placed multiple bets on the same selections without going full cover, you can just pick out the returns for each of your bets, without the need for separate calculations.
1st December 2015
The open beta phase has finally ended, and the new bet calculator has become the main entry point to the Free Bet Calculator website.
In response to a user request, the following new bets have also been added:-
- Magnificent 7
If you are not familiar with these bets and would like to know more, then there is a description of each one in the Betting Glossary.
The website’s bookmark icon (otherwise known as shortcut icon or favicon) has been updated to reflect the latest colour scheme, and further tweaks have been made to the website’s styling.
There are no bug fixes in this release, since there aren’t any known bugs remaining, but if you have encountered any issues, please report them via the Feedback form.
