Free Bet Calculator — FAQs

Is matched betting legal?

Yes — it's just two opposing bets. Bookmakers restrict accounts that only take promos, but it's not against any law.

Why SNR stakes lay less?

The free stake isn't returned — you only need to cover the profit, not the stake back. That's why free-bet lay stakes are smaller.
