Formula
9 selections in a 3×3 grid with 8 lines (rows, columns, diagonals). Each line has a Patent: 3 singles + 3 doubles + 1 treble = 7 bets. Total: 8 × 7 = 56 bets.
Includes singles, so even one winner on a line generates a return.
Frequently Asked Questions
What's a Union Jack Patent bet?
It lays your 9 selections out in a 3×3 grid and runs a Patent (3 singles + 3 doubles + 1 treble) on every one of the 8 lines. That works out to 56 bets in all.
How does it compare to a Union Jack Trixie?
The Patent version puts singles on each line too, so just 1 correct pick on a line can land you a return. A Trixie needs at least 2 to pay.
What does it cost?
56 × your unit stake. So at $1 a unit, you’re putting down $56 in total.
