One of the most popular promotions run by the best sports betting brands is the best odds guaranteed or BOG promotion. For those who are new to the promotion, it might just sound like marketing slogan for the site, saying that all the available odds at the site are extremely competitive; a claim we have all seen before. But actually, best odds guaranteed is a type of promotion where the betting site will pay you out on odds that are higher than what was original agreed on.
What is BOG?
Best odds guaranteed is a specific promotion, mainly offered on horse racing and greyhound racing. In some cases, it is offered on motorsport racing and other racing sports too. However, in most cases, you will find this promotion on sports betting sites that have a heavy focus on horse racing. It is particularly popular in New Zealand and Australia and at many of the UK betting sites.
Best odds guaranteed basically states that if you place a bet on a horse and the starting price ends up being higher than the original betting price, then the bookmaker will pay you out the latter. With horse racing, the starting price usually differs from the original betting price as horses drop out or are declared unfit. Usually this means the odds drop, as there are fewer horses in the race. A smaller field equals lower odds, as each horse has a slightly greater chance of winning.
Better Payouts on Shifting Odds
Sometimes the betting odds shift the other way around. This is not often seen with online or mobile sports betting, but it does happen. It may be that a horse was added to the program or new information was received about the surface, which greatly improves the chances of one horse winning but not others. In any case, sometimes the odds shift upwards on a horse which means that a punter would potentially lose out on a bit of cash.
For example, if a horse started out at odds of 2.60, but something happened and the starting price shifted to 3.50 this would mean that on a $100 bet, the higher odds would pay out $90 more. Without the best odds guaranteed promotion, punters would simply lose out on. If a betting site regularly offers the best football odds and best odds guaranteed on horse racing, even if the odds do shift. It might not happen that often, but when it does, the results can be extremely lucrative.
