This has got to be one of the best solitaire card games on the market. It has a fun background story (which does not interfere with the game play, but merely keep you involved to continue on your journey), relaxing music, and simple mechanics with fun powerups to assist you along the way. Well worth it at its current asking price of $10, and a steal at anything less. It has achievements, trading cards, and is guaranteed to waste a LOT of your time if you are a fan of Faeries whatsoever.
There are quickplay levels and extra hard challenge levels if you finish or need a break from the Adventure campaign.
If you have this in your library and haven't tried it out yet, you're missing out on a gem.
I read a review once that downvoted this because of no multiplayer option ... This is "Solitaire" ... Enough said LOL.
I wanted to add an edit into this:
If you are an achievement hunter, be forewarned that you have to collect a lot of materials and eggs while you play. This, of course, is governed by random odds. You may have to play quite a bit more to collect all the items you need, and several speculations and theories are presented in the forums.
Good hunting! :)
