Bet types: how each one pays and which one your bonus wants
Before betting on any sport it helps to know the basic structures: single, accumulator, system, handicap and over/under. Each calculates its return differently and each interacts differently with a betting bonus. This guide explains them with worked examples; the figures are illustrative and are not B777 conditions.

One selection. Stake $20 at 2.20 and a win returns $44. It is the easiest way to control risk and the one that works most cleanly with a bonus, because each bet counts at its full stake as long as it meets the minimum odds.
Accumulator (parlay)
Several selections on one slip, with the odds multiplied. Three legs at 1.70, 1.85 and 2.00 combine to 6.29. With $10, if all three win you collect about $62.90; if one loses, you lose everything. The probability multiplies too: even if each leg looks likely, all three landing is much less so. Some bonuses require accumulators; others do not let you use them for wagering.
System bets
A system bet builds several accumulators from the same selections. A 2-from-3 system, for example, is three doubles: if two of your three selections win, at least one double pays. It costs more, since each combination is a separate bet, but it tolerates one mistake.
European and Asian handicap
| Type | How it works | If the adjusted result is level |
|---|---|---|
| European (3-way) | Notional goals added, draw option included | The handicap draw wins |
| Asian whole line (-1, 0, +1) | No draw option | Stake returned |
| Asian half line (-0.5, +1.5) | Always a winner | Cannot happen |
| Asian quarter line (-0.25, +0.75) | Stake split into two halves | Half refunded, half settled |
Over/under
You bet on whether a total — goals, points, games — lands above or below a line. Half-point lines cannot push: with 2.5 goals, three or more is over and two or fewer is under. Whole-number lines can end in a refund if the total lands exactly on the line.
How they fit a betting bonus
A betting bonus's rollover is measured by the amount staked, with minimum odds per selection. Illustrative example: with a $200 requirement and a 1.60 minimum, ten $20 singles at 1.80 clear it; ten singles at 1.40 clear nothing. Refunds — for example an Asian whole-line handicap that pushes — usually do not count either. To apply this by sport, continue with football, basketball or tennis.
