Beginning from version 18.3, Bingo Missions were introduced. In each page, there are 3×3 mission slots. When you finish a row or a column of missions, rewards will be given. Completing 9 mission slots will give an additional bonus reward.
The basic and advanced difficulties have no time limit. Currently, each difficulty contains 3 pages, for a total of 6 pages. Event missions are time-limited, and must be completed within the event period in order to obtain the rewards.
