Excellent, addictive! I loved this so much I couldn't put it down for 2 days! A bit annoyed that I once I finished the main game I couldn't play the bonus game without purchasing it, not exactly a bonus if you got to pay! Apart from that I can't fault it, so much fun, amazing game play, graphics and puzzles, I did have to use my 10 free hints but I did waste lot. Can't wait for the next one!
