Now each daily reward is available only on the day of your first login.
Once you tap "Claim," you will see how Coins are credited to the balance, and how Boosters fly to the levels menu. You can choose those Boosters before the start of the next level.
The Loyalty system refreshes at 12:00 AM by local player's time. If you do not log into the game for 24 hours starting from 12:00 AM by your local time, your progress resets to Day 1.
If you miss one day or more, the progress will also reset to Day 1.
