The game sets up a large number of different levels, and each level has a specific mission objective. Common mission objectives include eliminating a specified number of patterns with royal crown elements within a specified number of steps. For example, players are required to eliminate 30 golden crown patterns within 25 steps. As the levels progress, the mission difficulty gradually increases. There will be various different styles of crown patterns that need to be eliminated simultaneously, or there are stricter requirements for the combination method of elimination.
