Best Welcome Bonus Online Casinos 2026

A welcome bonus is the offer a casino gives new players — usually a matched percentage of your first deposit plus free spins. But the headline figure only tells half the story: the wagering requirement decides whether that bonus can ever become withdrawable money. A £100 bonus at 20x wagering is worth far more than a £200 bonus at 50x. Below are our casinos with their minimum deposits; always read each casino's bonus terms and check the wagering requirement before claiming. Use our free casino check tool to compare licences and payout rates. Read our bonuses and wagering guide to calculate the true value of any offer. 18+ | Gamble responsibly.

Frequently Asked Questions

Which casino has the best welcome bonus?

Welcome offers change frequently and vary by country. DraftKings Casino, bet365 Casino, LeoVegas are among the casinos with well-known welcome packages. Always compare the wagering requirement, not just the headline amount.

Is a bigger welcome bonus always better?

No. A large bonus with a 50x wagering requirement is often worth less than a smaller bonus at 20x. Multiply the bonus by the wagering multiplier to see how much you must bet before withdrawing. See our bonuses and wagering guide.

How do I calculate the value of a welcome bonus?

Multiply the bonus amount by the wagering multiplier to get the total you must wager, then apply the house edge. A £100 bonus at 35x means £3,500 wagered; on a 4% house-edge game you would expect to lose about £140 clearing it. Read the terms before claiming. 18+ | Gamble responsibly.
