If you’re between 18 and 24, you can’t stake more than £2 per spin on any slot and for our over-25 readers, your max is set at £5. Gone are the days when you could let loose with £100 slaps.

Verify the casino's licence number directly on the Gambling Commission's official website, check that games are supplied by well-known providers such as Playtech, Nolimit City, Pragmatic Play or NetEnt, and confirm the site has been audited by a respected test house like eCOGRA or iTech Labs. To hold a UKGC licence, casinos may only offer games from approved providers whose slots are independently inspected by certified third-party testing labs. These audits verify that Random Number Generators (RNG) are truly random and that games pay out at their advertised rates. Key red flags include no UKGC licence displayed, in-house games that haven't been audited by accredited gaming labs and bonuses that seem too good to be true, like huge deposit matches with sub-10x wagering requirements. Unfortunately, many review sites never actually play at the casinos they recommend and just promote whichever sites pay the biggest affiliate commissions.
