Other sites on the White Hat network offer half as many spins, but with a win cap of £100, so to see a cap of £20 is very disappointing. It basically means that the maximum you can win for your £20 deposit is £20, a 100% match, but it’s not guaranteed, as you have to spin to win it. Also disappointing is the wagering requirement of 40x, which is not unheard of on UK casinos, but is higher than the wagering requirements on many competitors’ sites, including other White Hat sites. Overall, the offer is big, but the terms attached may make it less appealing, for sure. The next batch of suggested sites offer daily free spins deals and competitions that give you the opportunity to win free spins.
