How a system works
Pick your selections and a combination size. A 2/3 system takes every double from three picks: three bets. A 3/5 system takes every treble from five picks: ten bets. Each combination is a separate bet with its own stake, so the total stake is the unit stake times the number of combinations.

How many winners do you need?
With full-cover bets the answer depends heavily on the odds. At even money (2.00), a Yankee needs three of four winners for a profit, a Heinz four of six and a Goliath six of eight. At longer prices fewer winners are enough. Put your own prices into the system bet calculator to see the line.
System or acca?
| Acca | System | |
|---|---|---|
| Bets | 1 | Many |
| Total stake for ₦100 units | ₦100 | ₦100 × number of bets |
| Pays if one leg loses | No | Often yes |
| Best case | Highest | Lower per naira staked |
A system is a way of buying insurance against one or two losers. You pay for that insurance with a bigger total stake.
Where system bets are offered, they usually sit under a separate System tab on the bet slip. Limits on the number of selections, the minimum odds and how bonuses apply differ between bookmakers.
Questions
What does a system like 2,3/4 mean?
Every double and every treble from four selections: 6 + 4 = 10 bets. Tick sizes 2 and 3 in the system calculator.
Are system bets better value than accas?
No. They pay the same margin per bet. They change the shape of the risk, not the value.
What happens with a void leg?
It counts at 1.00 in every combination it is part of, so some doubles become singles.
