For any no deposit casino listed on our website you must be a new customer and be over the age of 18, and most likely have to provide SMS verification. If you don’t meet these criteria then it’s unlikely you’ll be able to opt-in and claim your bonus.
The vast majority of online casinos put these criteria in place since there’s a lot of bonus hunters who have historically hopped from casino to casino intending to claim as many bonuses as possible to cash out free money. This is almost impossible to do now (rightly so!) with all the latest compliance and regulatory standards in the UK, which helps advocate safe gambling practices online. (you can find more information here, regarding safe gambling).
