Click the menu icon in the top-right area of the screen to access the game menu. You can send and receive gifts through coins, spins, and cards by going to the "Gifts" menu and choosing "Gifts." As mentioned at the bottom of the gifts option, spins and coins donated to friends are not removed from your balance. Up to 50 spins can be sent or received at once in terms of spins! The town's status determines how many coins can be delivered and received.
