Every single day you can send a gift in form of one spin to your friends. They can also gift you! If you send someone a gift it doesn’t mean one spin will be removed from your account. You can get up to 60 spins each time and just as long as your spins bar is not full.
In order to send spins to your friends you have to press the menu icon on the top right corner of the game. A new screen will open. Press “Gifts” and you will be able to send gifts to your friends. You will also be able to collect spins, cards and coins.
It depends on your village level how many coins you can receive!
