Best Betting Sites and Online Casinos: How to Compare Them Before You Deposit

•       Game weighting: Slots may count 100% towards wagering, while table games may count far less or nothing.

•       Qualifying odds (betting): Free bets and bonus bets often need minimum odds.

•       Withdrawal caps: Some bonuses limit how much you can cash out.

•       Excluded payment methods: Some e-wallets don't qualify for the welcome offer.

Our bonus wagering calculator works out the total you need to bet and the likely cost of clearing a bonus, so you can decide whether it's worth taking. For offers negotiated with operators, see our exclusive deals.

A good rule: a smaller bonus with fair terms usually beats a big bonus with heavy conditions. And it's perfectly fine to skip a bonus altogether if the terms don't suit how you play.

Best betting sites vs. best online casinos: what is different?

The two overlap, but you judge them on different things.

Betting sites (sportsbooks) are judged mainly on odds, market range, live betting, cash-out options and limits on winning accounts.

Online casinos are judged mainly on game variety, software providers, live dealer quality, return-to-player (RTP) information and how game weighting works for bonuses.

Many operators offer both under one account, which is convenient, but the best sportsbook and the best casino are not always the same brand. If you use crypto, our lists of crypto betting sites and crypto casinos cover those separately.
