System Bets Explained

Bet types & conceptsSystem bets

A system bet (or full-cover bet) turns several selections into many smaller bets at once, so you can still get a return even if not every selection wins. This guide explains the common types with hypothetical examples only.

Key takeaways
  • A Trixie is 3 selections in 4 bets — 3 doubles and 1 treble, with no singles.
  • A Yankee is 4 selections in 11 bets: 6 doubles, 4 trebles and 1 fourfold.
  • An accumulator needs every leg to win.

What a system bet is

Instead of one all-or-nothing accumulator, a system bet covers many combinations of your selections — doubles, trebles and so on. Because of this, some selections can lose and the bet still pays something.

Trixie

A Trixie uses 3 selections in 4 bets: 3 doubles and 1 treble (no singles). At least two of your three selections must win for any return.

Example. With selections A, B and C, a Trixie places A-B, A-C, B-C (doubles) and A-B-C (treble). If only A and B win, the A-B double still returns.

Yankee & beyond

A Yankee uses 4 selections in 11 bets (6 doubles, 4 trebles, 1 fourfold). Larger versions (Lucky 15, Canadian, Heinz) add singles or more selections. Each combination is a separate stake, so total outlay is the unit stake times the number of bets.

System vs accumulator

An accumulator needs every leg to win; a system bet trades a higher total stake for the safety of partial returns. If you understand how odds combine via how odds work, the maths is just many small multiples added together.
