Once you complete all the available levels in Fiona's Farm, you can join the end-game competition: Best of the Best!
You'll be competing with other players and get the chance to win amazing rewards. Remember, Best of the Best lasts until new levels are out!
 
 
Note: You cannot earn energy by beating levels in the Best of the Best competition. Every 3 weeks, new puzzle levels will be added to the game. You can continue to earn energy by beating those new levels!
