Alex Kostin, Offersbet.co.uk: “I am always playing the same slots on the same sites. my favourite casinos that I always open when I need a break are Spin Rio, bet365 and Betfred. Why these three? Well, the bet365 has unique branded games, that no other sites offer, Betfred always has something for existing users like no wager extra bonus spins for selected slots (that’s a real deal for me) and SpinRio – well, it has all the hottest slots that I love to spin with max stake of £3-£5. Moreover, at these sites I can make fast deposits with Paypal, get money out quickly when there is a positive balance, of course and as always I prefer to play slots on my phone (when I am in bed).
