In horse racing, accumulator bets are bets where you bet on a winner (or placer) for more than one race. The more races you include in your accumulator bet, the more difficult – statistically speaking – it will be for you to win. This is why bookmakers can have very generous payouts for accumulator bets. These bets are tempting since they promise the chance of winning big on a very small wager, but you should be aware that the odds are very much not in your favor. Bookmakers tend to make a very nice profit on punters who do accumulator bets, especially on bets that include more than just two or three races.
When looking at a possible accumulator bet, always check how large the smallest possible win would be. Then compare that to how large a bet you would have to make (= how much money you must risk).
Different accumulator bets
Various accumulator bets are marketed under many different names, and even a bet that is called the same at two different bookmaker sites can have very different rules and terms. Some bet names are pretty descriptive (dobule, treble, etc) while others are more tricky to figure out. Do you know what a Yankee bet is? Or a Canadian? Or why not take your chances with a Trixie?
With most bookmakers, a Trixie is a bet consisting of 3 selections across 3 different races, where all combinations of doubles and trebles are bet (3 doubles and 1 treble). You get paid if at least two of the horses you wagered on win.
A Yankee bet is similar to a Trixie, but with four selections instead of three. This means six doubles, four trebles and one 4-way accumulator. You get paid if at least two of the horses you wagered on win.
A Lucky 15 also consists of four selections, which are combined to produce 15 bets derived from a Four-Fold Accumulator, four Trebles, six doubles, and one single for each selection. An important aspect of the Lucky 15 is that you get a bonus if all selection wins, while only one lonely winning selection will give you a consolation prize.
A Canadian (also known as a Super Yankee) is similar to a Yankee, but with five selections instead of four. This means 10 doubles, 10 trebles, five 4-way accumulators and one 5-way accumulator.
If you want to step it up further, you can go for a Heinz (six selections) or a Super Heinz (seven selections). There really is no upper limit, unless one is imposed by the individual bookmaker.
