In Pet Master, you have the ability to give your friends one spin each a day, and they can do the same! Doing so doesn’t take away from your spin balance, and you can collect up to 80 total spins per day (depending on your village). Please note, however, that these gifts can only be collected when you have less than 80 total spins in your balance.
To find your gifts, tap on the icon in the top right corner of the screen to open the menu and head to the “Gifts” section.
