Yes! You can earn 2 to 4 credits if you check in consistently.

Please kindly note that the check-in rules below：

1 Star: Check in for the first time.

2 Stars: Check in for seven consecutive days AND earn 14 ad credits during that time. Earn 7 ad credits and check in at least 6 days in one week, so you will not lose a star.

3 Stars: Check in for another seven consecutive days AND earn 28 ad credits during that time. Earn 14 ad credits and check in at least 6 days in one week, so you will not lose a star.

If you want to keep the stars you have, you need to check in at least 6 days and earn the corresponding credits every week. Don't worry if you forget to check in 2 days in one week and wind up losing a star. You can get it back by earning 30 ad credits in one week (from the day the star was lost).
