This booster can switch any two candies that do not match, as long as they are adjacent to each other.It can also, switch an igredient or a movable blocker( Liquorice Swirl or Candy Bomb).
Free Switch doesn't count as a move that's why it can be seen as "+1 move" booster.
When it is used on a special candy, this will not be activated, it will simply switch spots with the other candy.
Free Switch can be activated during gameplay in all types of levels.
This booster can be bought with gold bars, but is winnable from the Daily Booster Wheel and the Sugar Track.
