Bet Types with Worked Examples: Singles, Accumulators, Systems and Handicaps
The bet type decides how your slip settles and how much margin you pay. This page does not repeat textbook definitions — for each type it gives a simple worked example, so you can see what happens to your money. The basics of odds and margin are on the sports betting hub.
Single
One bet on one outcome. €10 at 1.90 returns €19 if it wins. The single is the clearest bet type and you pay the margin only once. If you are learning to bet, it is the best way to find out whether your picks have any value.
Accumulator (parlay)
Several selections on one slip; the odds multiply and the bet wins only if every selection wins. Three picks at 1.80, 1.90 and 2.00 make combined odds of 6.84, so €5 would return €34.20. Tempting — but the margin multiplies too. If each pick carries about a 5% margin, the theoretical return of one pick is 1 / 1.05 ≈ 95.2%, and of three picks 0.952 × 0.952 × 0.952 ≈ 86.4%. Every extra leg raises the cost of the bet.
| Legs in the accumulator | Theoretical return at 5% margin per leg | Expected loss per €100 |
|---|---|---|
| 1 (single) | 95.2% | €4.76 |
| 2 | 90.7% | €9.30 |
| 3 | 86.4% | €13.62 |
| 5 | 78.4% | €21.65 |
| 8 | 67.7% | €32.32 |
The calculation assumes the same margin on every leg and independent matches. Real margins vary by market.
System bets
A system is a set of combinations from chosen selections. A “2 from 3” system on matches A, B and C creates three doubles: A+B, A+C and B+C. At €3 per combination the whole bet costs €9. If two of the three win, one double pays; if all three win, all three pay. A system softens the blow of one failed pick but costs more in total. It is not a way around the margin — every combination carries it.
Double chance and draw no bet
Double chance covers two of three outcomes: 1X (home or draw), X2 (away or draw), 12 (no draw). Draw no bet backs a winner and refunds the stake on a draw. Both reduce risk and, with it, the odds. Which is cheaper you find out by converting the prices into probabilities and comparing them with the 1X2 market.
Handicaps: European and Asian
A European handicap adds whole goals and keeps three outcomes, including a draw after the handicap. An Asian handicap removes the draw and also uses half and quarter lines:
| Asian handicap on the favourite | Favourite's result | What happens to a €10 stake |
|---|---|---|
| −0.5 | wins by 1 | win |
| −1.0 | wins by 1 | stake refunded |
| −1.0 | wins by 2 | win |
| −0.75 | wins by 1 | half wins, half (−1.0) refunded |
| −0.25 | draw | half (0) refunded, half (−0.5) lost |
Quarter lines split the stake into two halves on different lines. For your first Asian handicap bets, write the outcomes out on paper — it avoids surprises at settlement.
Over/under, both teams to score and correct score
Over/under bets on total goals, points or games relative to a line. A half line such as 2.5 guarantees a clear result. Both teams to score is a yes/no market independent of the winner. Correct score has long odds because there are many possible results — and the margin usually rises with the number of outcomes.
Outrights
Bets on the winner of a competition or a league position settle after weeks or months. Your money is tied up all that time and the margin on these markets is often high, because it adds up across many possible winners. If an outright tempts you, remember you will not be able to use that stake elsewhere.
