Betting Guides

Everything you need to know about football betting, from the basics to advanced strategies.

An accumulator (or "acca") combines multiple selections into a single bet. All selections must win for the bet to pay out. The odds multiply together, creating higher potential returns — but also higher risk.

Example: 3-fold Accumulator

Arsenal to win1.80
Barcelona to win1.50
Bayern to win1.40
Combined odds3.78

100 kr stake × 3.78 = 378 kr return (278 kr profit). But if ANY leg loses, you lose the entire stake.

Key concepts

  • Legs: Each individual selection in the accumulator
  • Combined odds: All leg odds multiplied together
  • Correlation: Some legs are correlated (e.g. two teams in the same league). GoalSignal's Acca Builder uses a copula model to account for this
  • Implied probability: 1 / combined odds = your chance of winning (before margin)
