such a great game. Amazing puzzles and good graphics. You can easily get a good daily session out of this game for free, but because i have enjoyed the game so much i have purchased a few deals and items which has increased my playtime. Although overall the game is very good, there is a couple of drawbacks, my main one being that there is very little explanation for all the gems, rubys and coins systems and the items you can buy with them, but thats all really, other than that, its a top game

Some interesting and complex gameplay which is enjoyable. But every set of quests is locked behind having to kill monsters in a concentration game which is effectively v difficult beyond base levels without add ons, which while they can be crafted the pieces for are locked behind yet more puzzles..... etc etc. The help buffs for the combat games last a very short time so by the time you complete a few more quests it's worn off and you need another. After a while it gets v frustrating.

Definitely one of the best games I've played. It has hard levels but never impossible and you don't have to play games 50+times to win. It's easy to build up enough resources over time to enjoy the game without spending money but occasionally it's been helpful to buy extras. The games constantly change inbetween tournaments which keeps it interesting. I love this game and I hope the dynamic of the game doesn't change.
