We’d advise you to check the wagering requirements before you claim an offer. Ideally, you’d be looking for low wagering casino requirements whatsoever, but offers like that are really hard to find.

Bonus strategy: which welcome offer is right for which player

Before we recommend an online gambling site to you, we really put it through its paces.

Luckily, our experts at bookies.com really know their stuff, and they’re on top of exactly what makes an online casino great. The first thing we look for is a safe and secure experience. Any casino we recommend will be licensed by the UK Gambling Commission, which means that it’s legal for UK players.

Casino Promo Codes

We look for a good range of safe and convenient payment methods like bank cards, e-wallets, and prepaid cards. We even look for the best Neosurf casinos, Apple Pay casinos, best Boku casinos, MuchBetter casinos and PayPal casino sites. We’re a lot more likely to recommend a fast withdrawal casino that processes payments in just a few hours, or even instantly. One of the most important factors we consider is the game selection.

There’s also usually a maximum bet amount that you can place with an active bonus, for example it might be £5, or it could be a percentage of the bonus amount with a £5 deposit casino. But game restrictions and wagering requirements aren’t the only conditions on casino welcome bonuses. There might also be a maximum win limit set for a promo.
