This is a non-exhaustive list of traditional and popular bets offered by bookmakers in the United Kingdom. The ‘multiple-selection’ bets in particular are most often associated with horse racing selections but since the advent of fixed-odds betting on football matches some punters use these traditional combination bets for football selections as well.

Forecasts are bets on a single event that require the correct forecasting of the finishing order of (usually) the first two or three finishers in the event.[1] Returns on correctly predicted finishing orders are calculated by industry sources via computer software that uses the starting price of all participants in the event, and are usually declared to a £1 stake unit on (mainly) horse and greyhound races.
A straight forecast or computer straight forecast is a wager requiring the naming of two selections a and b to finish 1st and 2nd in the correct order in a specified event.[1] Requires a single unit stake. Usually declared on horse and greyhound races of three or more runners. Equivalent to the United States exacta or perfecta, or the Canadian exactor.(資料來源 )
A reversed forecast (RF) is a wager requiring the naming of two selections to finish 1st and 2nd in either order in a specified event.[1] It is the same as two straight forecasts on selections a and b: a 1st, b 2nd and b 1st, a 2nd. Requires two unit stakes. Equivalent to a “boxed” exacta/perfecta in North America, where the quinella is a similar wager that requires only one unit stake.
A combination forecast is a wager on three or more named selections in order to choose two of the selections to finish 1st and 2nd in the correct order in a specified event.[1] It is the same as the number of straight forecasts on selections a, b … n given by the formula n(n − 1) and therefore requires this number of unit stakes. E.g. 3 selections – 6 bets; 4 selections – 12 bets; 5 selections – 20 bets; etc. Equivalent to boxing an exacta/perfecta with more than two runners in North America. (資料來源 )
