What is a Union Jack Bet?

A bet on nine selections, consisting of between 8 and 80 bets depending on the type.

Union Jack

Named after the Union Jack due to the way groupings are determined, by laying out the selections in a 3 by 3 grid then drawing lines vertically, horizontally and diagonally to find 8 groups of 3. A benefit of this bet is it gives the punter scope to arrange their bets such that their most favoured selections have a greater bearing on returns than their least favoured. Position E appears in 4 trebles, positions A, C, G, I appear in 3 trebles and B, D, F, H only in 2. To work out returns or experiment with stakes and selection positions try one of the union jack calculators for trebles, trixies, patents, or round robins.

Bookmakers often make available special betting slips to place this type of wager laid out in the style of a Union Jack.
