You can Reset your game by tapping on "Trophy" at the bottom on your screen and then tapping "Reset & Collect".

When you Reset the game, you earn Trophies. Each Trophy you collect will boost your Cash production.

You need to Reset to collect Trophies, removing all your progress. Don't worry! You keep all your Trophies, Keys and Courses.

You may not be able to Reset immediately after a previous Reset, as you won't have enough Cash to earn Trophies.
