When placing a System bet, you choose how many correct selections you need to win. The number of selections that determine a System win is called the size.
What makes a System bet?
A System is made up of Multiples. At least one Multiple in the System must be predicted correctly to win.
The total bet amount in a System is divided equally between all of its Multiple bets. The minimum bet amount is equal to the number of Multiple bets in the System, but can't be less than EUR 0,5. The System winnings are equal to the sum of the winnings of the Multiple bets included in it.
Let's take a look at the 2 out of 3 System

A System bet can include any selections, such as totals, handicaps and player statistics
There are three events in this System. You'll win if at least two of the events were predicted correctly. To calculate the winning options, break down the System into three Multiples.

The total bet amount in a System is divided equally between all of its Multiple bets. This bet consists of three EUR 10 Multiple bets
Let's see your winnings depending on the various outcomes.
- If two or three events are not predicted correctly, then all Multiple bets intheSystem will lose.
- If one prediction for one of the matches turns out tobewrong, then thetwo Multiple bets including itdon't win. You receive winnings forone Multiple.
- If all three events were predicted correctly, you'll receive thewinnings forthree Multiple bets.
What you need to know about System size?
System size is the ratio of the number of selections that are needed to win, to the number of events in the System.
The size is specified as 2 out of 3, 3 out of 5, 7 out of 10. A 2 out of 3 System bet means that the bet has 3 events, 2 of which need to be predicted correctly for the bet to win.
The larger the size and number of Multiple bets in a System bet, the larger the minimum bet size.
System size restrictions
- The maximum number of events in a System is
16.- You can't create a System where only 1 event needs to
bepredicted correctly, such as1 outof10, or1 out of3.- You also can't create a System where all the events need to
bepredicted correctly, forexample, 3 out of3, or10 out of10.
For a System of 5 events, you can choose different sizes, such as 2 out of 5, 3 out of 5, or 4 out of 5. The more events needed for a System to win, the higher its odds.
How to calculate the number of events in a Multiple
The number of events in each Multiple is the same as the first number in the System size. In a 5 out of 7 System, for example, the Multiples consist of 5 events.
To calculate the number of Multiple bets, use the formula:
m! ÷ (n! × (m - n)!)
- m – number of events in the System
- n – number of events that must be predicted correctly for
theSystem towin- ! – factorial
For example, a 5 out of 7 System bet will include 21 Multiples:
7! ÷ (5! × (7 - 5)!) = 5040 ÷ (120 × 2!) = 5040 ÷ 240 = 21
We also made a table that helps determine the number of Multiple bets in the System, without using the formula.

The red vertical column is the number of events in the System, and the blue horizontal row is the number of correct selections needed to win
To calculate the number of Multiple bets, select the row with the number of events in the System, and the column with the number of selections needed to win. The number of Multiple bets is shown in the intersection of the column and row.
How to calculate System winnings?
The easiest way is to use the
System calculator
. The calculator helps calculate the number of Multiple bets in the System and their winnings. The calculator is only available on the desktop version of the site.In order to calculate the potential winnings of the system and number of combinations, indicate the number of events in your system, its size, odds and bet amount. For events settled as returns, enter odds of 1.00.
A System bet can lose you money even if it wins
The amount of winnings is determined by the Multiple bets which make it up. If the amount of the bet and odds of the Multiples with winning events are small, then the bet may win even with a negative amount, if the conditions are met.
You bet EUR 90 on a 2 out of 3 System bet with odds of 1.50, 2.00 and 1.60. Let's break it down to Multiples:
- 1.50 and 2.00, bet amount – EUR30
- 2.00 and 1.60, bet amount – EUR30
- 1.50 and 1.60, bet amount – EUR30
The events with odds of 1.50 and 1.60 won, and the event with odds of 2.00 lost. Out of the three Multiples, only one of them won. Let's calculate how much you won:
1.50 × 1.60 × 300 = 2.40 × 30 = EUR 72
The one winning option earned you EUR 72 on the EUR 90 you bet. Technically the bet won, but you ended up in the red.
What's the difference between a System and a Multiple bet?
- The maximum number of events in a System bet is 16 (30 in a Multiple bet).
- Not all events in a System bet need tobepredicted correctly for the bet to win. You choose thedegree ofrisk anddetermine howmany events need towin forthebet towin. All events need tobepredicted correctly ina Multiple bet, otherwise thebet will not win.
- Also, a Multiple bet can consist oftwo events, while aSystem bet must have atleast three. This isdue tothesize limitation: you cannot bet onaSystem where just one orall events need topass to win.
- System bet winnings will always be less. Thisisbecause aSystem consists ofMultiple bets whose winnings aresummed up. Ina Multiple bet, thebet odds aremultiplied.

With a bet of EUR 10, the maximum System bet winnings would be EUR 38,27, while the winnings of a Multiple bet would be EUR 74,40
How do I place a System bet?
- Add at least three events to the bet slip.
- In the Bet Type section, select System and indicate the size.
- Enter your bet amount.
- Click on the Place Bet button.
