Boosters help you complete solitaire levels. You can get them as a reward for completing some levels and also buy them with coins.
 
Each booster has its own purpose:
  • The Double Wild booster adds two Wild Cards to the stock at the beginning of the level and should be added before the level start. Using it you can remove any card from the table.
  • The Fan booster removes all open cards and should be added before the level start.
  • The Triple Cut booster removes 3 open cards from the table and should be selected before the level start.
  • The Wild Card booster helps to remove any card from the table.
  • The Extra Cards booster adds 5 cards to the deck. 
    When you purchase a Gold Ticket in the Energetic Season, this booster will add 7 cards until the end of the Season!
  • The Undo booster undoes your last move.
  • The Double Coins Booster doubles the coin reward per level.
 
You can get boosters as a daily reward, as a reward for timed game events, as well as to win in Wheel of Fortune or buy with coins.
