How to change the account of the fat goose gym applet?

You can't change it, you can only cancel it or play with a new account.

Fat Goose Gym can only re-cancel the account, or change the micro signal to play again. The game can't be played after your information is authorized, so you can only cancel it or open another number.

You can get a reward for upgrading the level of the gym, or you can get a specific reward for building a gym. You can click on the construction target or check the reward details in the circle of the checkpoint and get what you need first.
