Daily Stamp Rally
In the Daily Stamp Rally, collect Stamps every day and they'll be placed on your Stamp Sheet sequentially. Stamp a reward space to get its rewards.
Stamps can be acquired from Mission rewards after completing each day's Daily Missions, but if the Stamp for the previous day is not collected before the date changes, the Stamp Sheet will reset.
Once a Stamp Sheet has been completed, a new one will begin when the date changes.
