Once you have completed all of the current levels (new levels are released roughly every two weeks), you will have the chance to take part in the Culinary Genius League and show off your skills by competing for a place on the leaderboard.
In the  Culinary Genius League, you play Stages which are repeats of past levels you have completed in the past. Each Stage you win will earn you Trophies.
You earn 5 Trophies with each Stage you complete. 
The Trophies you earn will determine your place on the Leaderboard with our other players, rewards you earn will depend on your position in the League when it ends.
You can return to the League at any time by tapping on the League icon on your home screen.
Trophies collected will reset at the end of each event.
