Mini Games are what the name suggests. These minigames listed below can be played only when a pony is avaliable to play them, as indicated by an icon over their residance, or the timer in the pony's infomation screen.
The Mini Games cycle round for the pony everytime you play a mini game with it. After the mini game, the pony gets parts of a star. The better your score, the more parts you get. Each pony has 5 stars, and once a pony gains a star, they can play the Clear the Skies mini game.
