Parlay betting combines multiple individual wagers into a single bet slip, requiring every selected outcome to be correct for the bet to pay out. While the potential payout is higher than placing each bet separately, the risk increases because a single incorrect result causes the entire parlay to lose.
How Parlay Odds Are Calculated
Sportsbooks multiply the odds of each leg to determine the overall parlay odds. For example, three point‑spread picks at -110 odds yield a combined payout of approximately +586 (6.86 times the stake). The same principle applies when mixing bet types — such as a point spread, a total, and a money line — across different sports.
Common Parlay Restrictions and Same‑Game Parlays
Most sportsbooks prohibit combining the point spread and money line on the same favorite within one parlay. Same‑game parlays (SGPs) allow multiple bets from a single contest, though odds may be adjusted slightly. For instance, a bettor could parlay the Kansas City Chiefs’ spread and the game total in an NFL matchup, or combine player props like LeBron James’ points and Kevin Durant’s rebounds in an NBA game.
Sports Where Traditional Parlays Are Limited
Events with a single winner — such as golf tournaments or Formula 1 races — generally do not allow parlays on multiple competitors to win. However, markets like “top‑5 finish” or “top‑10 finish” can be parlayed as long as the selections do not conflict (e.g., Lando Norris to win, Lewis Hamilton top‑5, Oscar Piastri top‑5).
Other Parlay Variations
SGP+ or SGPx bets merge same‑game parlay legs from different games into one slip. Teasers shift point spreads or totals in the bettor’s favor at reduced odds. Round robin parlays create multiple smaller parlays from a set of picks (minimum three), paying out if any combination wins, though profit is not guaranteed with only one winning combination.
Choosing a Sportsbook and Managing Risk
Major sportsbooks like DraftKings, FanDuel, and bet365 all offer parlay betting, with differences in odds and promotions such as profit boosts on same‑game parlays. Experts advise keeping parlays to four legs or fewer, wagering smaller amounts, and recognizing that sportsbooks pay less than the true mathematical probability, making long‑term profitability difficult.
Parlay Odds vs. True Probability
A comparison table shows the gap widening as legs increase: a two‑leg parlay at -110 per leg has a true implied probability of 25% (+300) but pays at 27.4% (+264.5); a ten‑leg parlay’s true probability is 0.1% (+102300) while the paid odds are only 0.2% (+64208). This illustrates why fewer legs improve the chance of a return.
Frequently Asked Questions
A parlay is any wager with two or more bets. An example is combining the money lines of the Giants, Patriots, and Vikings in one bet. Parlay types include traditional, same‑game, SGP+/SGPx, teasers, and round robins. Parlay betting is considered high risk because one loss voids the entire ticket, and payouts are below true odds. Most sportsbooks offer parlays, though leg restrictions vary. If a leg pushes, the sportsbook typically removes that leg and recalculates the odds for the remaining legs, but policies differ by platform.
