What is an Accumulator?

An accumulator (acca) combines 4+ selections into one bet. All selections must win for your bet to pay out. The odds of each selection are multiplied together, creating much bigger potential returns.

๐ŸŽฏ

Parlay vs Accumulator

They're the same thing โ€” "parlay" is the American term, "accumulator" is used in the UK. Both combine multiple selections with multiplied odds. A treble = 3 selections, 4-fold = 4 selections, etc.

Pro Tip: Odds Format

Decimal odds of 2.00 = evens (1/1 fractional = +100 American). Anything above 2.00 is odds-on favourite territory. Always check which format your bookmaker displays before entering.
