Parlays & Accumulators

6 min read

A parlay (or accumulator) rolls several bets into one for a much larger payout — but every leg must win. Here's how the maths and risk really work.

How acca odds multiply

Each added leg multiplies the odds — and the risk. Four 60% selections look strong individually, but the chance all four land is only about 13%. Bigger accas pay more precisely because they're far less likely to win.

Use an odds calculator to see the true payout and stake against the combined probability, not the headline return.
