How the Union Jack Patent calculator works
Each of the eight lines in the grid becomes a patent (three singles, three doubles, one treble), totalling 56 bets. The calculator aggregates per-line results, shows contribution to the total, and updates active lines as selections settle.
- Line-by-line patent summaries with gross and net results.
- Each-way toggle with flexible place fractions and places.
- Active line tally as results land across the grid.
- Commission and free bet inputs for net precision.
- Copyable per-line reports for your tracker.
When to use the Union Jack Patent calculator
Ideal when you crave maximum cover from the union jack format, especially on volatile racing or darts cards. Useful for spreading risk while maintaining clear upside paths.
Make smarter staking decisions
Inspect the single bet contribution per line to understand where the bulk of cover sits. If singles dominate returns, consider whether a lighter trixie structure would suit your goals.
