A single bet is one bet on a coupon. This is the most popular type of bets among professional players due to a very simple reason – it has bigger chances for a win (from 33 to 50%) rather than betting on 2, 3 or 5 events on a coupon. For playing with single bets you should have bigger capitals.

Doubles are a kind of bet placed on two events. In order for such bet to win both events have to be predicted correctly (win). The probability of prediction of a double bet is lower than a single bet, what is intelligible from mathematical and theory of probability points of view. A triple bet is in its turn a coupon with three chosen events – works on the same principles as the double bet.

Multiple betting which consists of several events is also well-known as combo. Different kinds of bets can form combo: 1X2, handicap, over/under and so on. Multiple bets are also frequently called combined (combo) or accumulator (Parlay). Winnings in multiple are much bigger than in single or double bets but the percentage of misfortune is also higher.

System betting is nothing else than a complex of combo bets of a defined size out of a fixed suit of sporting events. For this type of betting several matches are chosen depending on the system for example 2 out of 3 or 4 out of 6. Then combinations are created, single or group in each system. If all events are guessed the whole system bet wins. In its turn if you win for instance 4 out of 6 events (in the 4 out of 6 system) then you also win but the winning will be much lower and in case of low odds might even not cover the sum of money bet on the coupon. Probably it is not needed to remind that there are fewer winnings in systems than in combo.
