Union Jack Patent Calc
9 picks in a 3x3 grid, a Patent on each line.
How to Use This Calculator
- Drop in your unit stake
- Punch in odds for all 9 selections (laid out across a 3×3 grid)
- Flag the result (won/lost/void) for each selection
- Read off your total return, broken down line by line
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 exactly is a Union Jack Patent bet?
A Union Jack Patent lines up 9 selections in a 3×3 grid and slaps a Patent (3 singles + 3 doubles + 1 treble) onto each of the 8 lines — 56 bets all told.
How does it stack up against a Union Jack Trixie?
The Patent version bolts singles onto every line. That means a single correct pick on a line is enough to cash, while a Trixie demands at least 2.
