Check the small print

Some boosts only count the first part of your stake, or cap the extra winnings. Pick the right limit or your lay will be too big.

Effective odds

We turn the boost into the odds you're really getting, then lay at those. A capped 25% boost on 5.00 might only be worth 5.50.

Paid as cash?

This assumes the extra winnings are paid as cash with the bet. If it's paid as a free bet, the real value is lower.

Matched betting hedges both outcomes, but odds can move and mistakes can still cost money. 18+. Free help at BeGambleAware.org.
