Bet Types: Singles, Accumulators, System Bets and Handicaps

The bet type you choose decides three things before the event even starts: how much you can win, how much of the bookmaker's margin you pay, and how long your money stays tied up. This page compares singles with accumulators (called parlays in some countries), breaks down the common system bets, and explains handicap and over/under lines with worked numbers. Which of these the Nano bet slip accepts is something to check in your account; the examples below use neutral units, not anyone's real limits.

Single versus accumulator (parlay)

A single is one selection: stake times odds is the return. An accumulator joins several selections on one slip and multiplies their odds. Take a hypothetical four-leg accumulator at 1.50, 1.70, 2.10 and 1.40. Combined odds are 1.50 × 1.70 × 2.10 × 1.40 = 7.50 (rounded), so 10 units would return about 75. Every leg has to win.

The hidden cost is margin. If each leg carries roughly 5% overround, four legs together carry about 1.05 × 1.05 × 1.05 × 1.05, or around 22%. Accumulators are not wrong, but they are the most expensive way to bet on the same opinions, which is exactly why bookmakers like to boost them.

If one leg is void, it is normally counted at 1.00. Voiding the 2.10 leg in the example leaves 1.50 × 1.70 × 1.40 = 3.57, and a potential return of 35.70.

System bets: full cover in one slip

A system bet places every combination of your selections as separate bets, so you can collect without every pick winning. The names come from tradition rather than logic:

Name	Selections	Bets	What it contains
Trixie	3	4	3 doubles and 1 treble
Patent	3	7	3 singles, 3 doubles, 1 treble
Yankee	4	11	6 doubles, 4 trebles, 1 fourfold
Lucky 15	4	15	A Yankee plus 4 singles
Super Yankee (Canadian)	5	26	10 doubles, 10 trebles, 5 fourfolds, 1 fivefold

Cost scales with the number of bets: a Yankee at 1 unit per line costs 11 units, not 1. That is the trade-off for being paid when only some selections land.

Handicaps: European and Asian

A European handicap adds or subtracts whole goals and keeps three outcomes. If the favorite is -1 and wins by exactly one goal, the bet that wins is the handicap draw. An Asian handicap removes the draw and uses lines that can refund all or part of the stake. Quarter lines split the stake in two. Worked example: 20 units on a favorite at -1.25, price 1.95. Half the stake goes on -1, half on -1.5.

Favorite wins by two or more: both halves win, return 39.
Favorite wins by exactly one: the -1 half is refunded (10), the -1.5 half loses, so you get 10 back.
Draw or defeat: both halves lose.

Over/under lines in any sport

Totals exist for goals, points, games, runs, corners and cards. The line type matters more than the sport. A half line (2.5, 214.5, 21.5) always produces a winner. A whole line (3.0) refunds the stake if the total lands exactly on it. A quarter line (2.75) splits the stake across 2.5 and 3.0. Sport-specific examples are on the football, basketball and tennis pages.

Bet type and your withdrawal

Bet type	When the stake is released	Cashier note
Single	When its event is settled	Fastest route back to a withdrawable balance
Accumulator	When the last leg is settled	Stake locked for the life of the slip
System bet	Line by line as events finish	Partial returns; several lines open at once
Asian handicap or whole-line total	When the event is settled	Refunds and half refunds rarely count towards wagering

If the stake came from a betting bonus or free bet, check whether winnings arrive as cash or bonus funds, and whether minimum odds per leg apply to the wagering. Then verify your identity before the first payout and use a payment method in your own name. The withdrawal guide covers statuses and delays, and the wagering guide shows how to calculate what is left.

Frequently asked questions

What is the difference between a single and a parlay?

A single depends on one selection and pays stake times odds. A parlay, also called an accumulator, multiplies the odds of several selections but loses if any one leg loses, and the stake stays locked until the last leg is settled.

How many bets are in a Yankee?

Eleven: six doubles, four trebles and one fourfold from four selections. At one unit per bet, a Yankee costs eleven units in total.

How does an Asian handicap of -1.25 settle?

The stake is split between -1 and -1.5. A win by two or more pays both halves. A win by exactly one refunds the -1 half and loses the -1.5 half. A draw or defeat loses both halves.
