To restart from level 1, you can consider the options below:

1. If you have never logged in with your Facebook or Apple account on the game's Settings before, please delete the app and then reinstall it.

2. If you are already logged in, you can use the Delete Account feature.

Kindly refer to the article How can I delete my account?

Please note that both options will result in the loss of your game progress, including levels, coins, and boosters. This data CAN NOT be restored afterward.
