Collect Stamps from purchases to fill your Loyalty Card for a bonus reward. Most Cherry bundles in the Store will include a Stamp. Cherry bundles and special offers that include a Stamp will appear with the blue owl icon.

 

Check your Loyalty Card progress in the bottom-right corner of the Store.  Tap on the corner white arrow on your Loyalty Card to check your current bonus and the time remaining before it resets. 

The size of the bonus reward depends on the average value of your purchases that include Stamps.

 

The Loyalty Card resets every month so be sure to complete it for rewards before then.
