An Octopus slip stretches across several outcomes at once — each leg a tentacle. Add your legs below and we will show the combined price, the true probability of the whole thing landing, and where the legs work against each other.
Fixtures are today's real matches from our data feed. Enter the price your bookmaker is showing for each selection.
Adding legs multiplies the price. It also multiplies the ways the slip can die.
Six legs at 80% each look strong individually. Together they land roughly 26% of the time. The price rises because the probability falls — that is the entire trade.
Every leg carries the bookmaker's margin. Stacking eight legs stacks eight margins, which is why long multis are the most profitable product on any betting site — for the bookmaker.
Two selections from one fixture are not independent. Where we spot them on your slip, we flag it — the true probability differs from a simple multiplication.
A nod to the famous octopus. This picks a fixture at random from today's card — it uses no data, no model and no judgement whatsoever.
