When to use the Union Jack Trebles calculator
Ideal for football coupons, darts sessions, or racing multiples when you want geographic or time-based spread across a card. Helpful when you want lightweight cover without committing to patents or trixies.
Make smarter staking decisions
Use the layout view to ensure every selection is in the optimal slot before you place the bet. If one diagonal looks much stronger, consider stake weighting or compare to the trixie/patent union jack variants.
