I've just played that new Deal or no Deal game on there. One of the features gives you free spins with all wins doubled, until a banker symbol appears on the middle reel. I was playing on 20p a spin and had the feature twice. The first time the banker came in straight away and I won nothing, the second time I had a 10p x 2 win, then the banker came in. Great stuff
But yes, I do like playing some of the games on there. You are going to lose in the long run obviously, but if you play 20p a spin it's good fun. I had a feature on Reel King go for 100 quid on 20p a spin, so that's the eqivalent of getting 500 on 1 pound a spin. My friend had a full screen of bags come in last weekend, also on 20p a spin.
Some of the promotions are quite good - new users get a 10 quid bonus after they've played off 20 pounds' worth of games. I played 112 games on Lucky Lady's Charm on 18p a spin at 97.11%, lost about 60p but got my bonus.
