There are rarely minigames. Instead you have challenges, which are very, very, very, very hard to win unless you use a lot of power ups and bonuses (even then sometimes you won't win) and you lose one life and whatever additional power ups you get from the treasure chests or top hat. There should be an option to participate in the challenge levels. Also the events/seasons seem very hard to complete unless you spend money for coins or can play levels all day
