Player Reviews
“Proper British site this, no faff. Love The Goonies slot, so many different features. Got the Fratelli Hideout bonus and picked a blinder. ‘Hey you guys!’... right into my wallet.”
“Sometimes you just want a simple, low-stress spin. Starburst is the one. Was on a bit of a cold streak, switched to this and it brought my balance back up nicely. This site's built for us Brits.”
“The original and still the best Megaways. The bonus is so hard to get but when you spell out GOLD... magic. The unlimited multiplier is just insane. Quick withdrawal to PayPal as well.”
“Not a slot, but their live casino is spot on. Was on Crazy Time, hit a 10x multiplier on Cash Hunt and picked the right symbol. Great fun with the host, proper laugh.”
“An old school classic, takes me back to the bookies! The free spins bonus with the 3x multiplier is what it's all about. Simple, but it does the job. 21.co.uk feels like a safe bet.”
