Your LINE friends send hearts to you and they arrive in your Mail Box. If you accept the messages within an hour, you receive 200 coins per message. When you accept the messages one at a time (regardless of how long it's been since it was sent), your LINE friend receives a heart in return. If you use the "Claim All" button, your LINE friends don't receive a heart in return. Hearts will be saved in the Mail Box for up to 30 days.
- Tip: Messages that were sent 1 hour and 0 minutes ago can sometimes still give you 200 coins, even if they don't have a coin image in the upper right corner of the "Check" button.
