A Bet Builder and an Accumulator (Acca) are both multiple selection bets, but they work differently.
What is a Bet Builder?
A Bet Builder lets you combine multiple selections from a single match. For example, you can combine a match result, a player to score, and a number of corners, all within the same game.

What is an Accumulator?
An Accumulator lets you combine selections from different matches or events. All selections must win for the bet to pay out.

Key differences
| Bet Builder | Accumulator |
Number of events | One match | Multiple matches |
Selections | Different markets within the same match | One selection per match |
Odds | Combined and adjusted | Multiplied across all selections |
Example | Result + first goalscorer + over 2.5 goals (same game) | Three teams to win across three different games |
What they have in common
One losing selection means the whole bet loses.
Both offer higher potential returns than a single bet.
