Player Reviews
“It's a small site, not a massive choice, but it has the classics. Starburst does the job when you just want a quick, simple spin without too much thinking. It is what it is.”
“A fast-paced little game. The free spins trigger on any fruit line, so you're always in with a chance. Good for a low-stakes session. The site is no-frills, but it works fine on mobile.”
“Thank god they've got Fishin' Frenzy, every casino needs it! The bonus dropped and I landed a few decent fish. A solid, if small, selection of games. Does the job for a quick punt.”
“Was looking for the live casino but they don't have one, gutted. Had a spin on 9 Pots instead. Landed 7 pots for a decent instant win. It's alright for slots, I suppose.”
“The money respin feature is what you're after here. The wolves were howling! Filled up a good chunk of the screen. A good solid game. The casino is basic but it's UKGC licensed, which is the main thing.”
