Accumulator (acca)

An accumulator is one bet on several selections in which every leg must win. The odds multiply, so the payout grows fast, and so does the chance of losing.

Example

Four legs at 1.50, 2.00, 1.80 and 2.20 make odds of 11.88. A stake of 10 returns 118.80 if all four win, and nothing if any of them loses.
