Customers will come into your Haven looking for a cuddly bun to snuggle! A little star will appear beside the Customer which shows their level. They will also have a little thought bubble with a picture in it which indicates their personality trait.
Bunnies can be paired with a customer of the same level or less, so higher level customers will require higher level Bunnies, and you can earn bonus hearts for pairing up a Bunny and a customer that share the same personality! You can still pair Bunnies and customers with different personalities though with no penalty. Pairing higher-level Bunnies with higher-level customers will earn you more hearts.
Tap on a customer and a spotlight will illuminate them, and a toolbar will open along the bottom of the game showing all the Bunnies available to pair! Then simply tap and drag the Bunny you think will pair best to your customer, and they will pair up for a snuggle!
