The background story:
Pony Princess Celestia a unicorn has gems broken into two pieces, and her pony subjects (including some unicorns such. B. Rarity), they have to put it together again.
The Game:
Each player selects one or two ponies and thus determines what type of gems he has put together. That is, if it is his turn, he must try to insert the appropriate game card so that a gem of the same color will be complete again. At the end there is for each composite stone one point, there is an image of Celestia on one of the two cards, there are two points. It is located on both cards, there are four points.
It is in the nature of the game, that the end result is always very scarce. This is less a good tactic, because the rules are generally very easy knit. Meaning the game seems to be more, especially children (not only girls) to stay entertained. Therefore the whole ponies and gemstones instead of dominoes.
Shuffle, My Little Pony is beautiful to look at and fun. This game can be seen primarily as a child-friendly development of Domino. So you have nothing really new in the house.
