What Is a Parlay Bet?
A parlay (also called an accumulator or multi) is a single bet that links two or more individual wagers. All legs must win for the parlay to pay out — but because the odds multiply together, even a modest parlay can return significant profit from a small stake.
How Are Parlay Odds Calculated?
Each leg's odds are first converted to decimal format, then multiplied together to produce the combined decimal odds. That figure is then multiplied by your stake to give the total payout. Subtract your stake and you have the net profit.
For example, three -110 American odds legs convert to roughly 1.909 decimal each. Multiplied together: 1.909 × 1.909 × 1.909 ≈ 6.96. A $10 stake returns $69.60 — a profit of $59.60.
Parlay Betting Tips
Fewer legs = lower variance. Every leg you add multiplies both the potential payout and the chance of losing.
Avoid correlated legs. Combining outcomes that depend on the same event (e.g. a team wins and covers) can void parlay payouts at some books.
Reduced juice matters. At bet105, standard lines are -105 instead of -110 — that means your parlay odds are always better than at a standard sportsbook.
Use parlays as a complement, not a strategy. Sharp bettors use parlays selectively — pair them with +EV single bets for a balanced approach.
Why Bet Parlays at bet105?
bet105 offers reduced juice (-105) on standard lines, no limits on winners, and payouts in roughly 2 hours. That means every leg of your parlay starts with better odds than you'd get at a -110 book — and if you win big, you'll actually get paid.

Our Parlay Builder supports up to 20 legs. In practice, most sportsbooks including bet105 allow large parlays, but payouts are capped — always check max payout limits before placing a big multi-leg parlay.
The Parlay Builder supports American (moneyline) odds and Decimal odds. You can switch between formats at any time and all entered values will convert automatically.
If one leg of your parlay pushes (ties), most sportsbooks including bet105 drop that leg from the parlay and recalculate at the remaining legs' odds. The parlay does not lose — it just becomes a smaller parlay.
Yes — significantly. Each -110 leg in decimal is ≈1.909. Each -105 leg is ≈1.952. On a 4-leg parlay, that difference compounds: 1.909⁴ ≈ 13.3 vs 1.952⁴ ≈ 14.5. That's nearly 9% more payout from the same bet, just from betting at bet105 instead of a -110 book.
Parlays are higher variance — all legs must win. They are not +EV by default, since the house takes a margin on each leg. However, when used with +EV legs, or when taking advantage of promo boosts, they can be a smart play. Use our EV Calculator alongside this tool to check each leg before adding it.
Convert each leg's odds to decimal, multiply all decimal odds together, then multiply by your stake. That gives your total payout. Subtract your stake for net profit. Our calculator does this instantly — but now you know the math behind it.
