Virgin Casino. Jekyll and Hyde is a great looking video slot with 243 Ways to Win, Wild and Scatter Symbols & 3 or more scatter symbols triggers the Mr. Hyde Free Spin Feature. Dr. Jekyll is the highest paying symbol at 1500 coins but increases in value when he changes into Mr. Hyde, up to 7,500 coins worth, for 5 on a winning payline.
Also new at Virgin Casino is Retro Reels Extreme Heat slot which has a Re-Spin feature and Free Spins feature too and there's also the good looking Hawaiian Treasure slots game which has wild symbols and Free Spins Bonus round.
I was playing at Virgin Casino qute a bit last week - I think they've got a very well designed site with easy access to free play/demo modes of their games plus there are plenty of bonus offers and promotions (right now all new players can get up to £100 Free).
This being a Microgaming casino it isn't suitable for US players.
