You receive gifts for logging in to the game every day. Open the Daily bonus tab to claim your reward:
Note: You need to collect gifts manually. They are not added to your account automatically.
Gifts do not depend on the date of the month. If you miss a day, you will receive a reward starting from the day you have missed.
On the first day of each calendar month, the counter of the collected rewards is reset. You start collecting rewards from the first day of the month.
