If a slot site isn’t transparent about its licence or regulatory commitments, we won’t feature it.

Some of these offers claim to be worth hundreds of pounds, but upon further investigation, they aren’t as lucrative as they first appear. The changes to gambling laws mean bonuses will soon be capped at 10x wagering before turning into cash, but that could still mean the headline value of the offer is diminished after wagering has been completed. The Independent’s in-house gambling experts and I consider everything from wagering requirements, time limits and eligible deposit methods.
