New Puzzles!

On August 19, “Round 4” will be added to the Puzzles mode, which will feature three puzzles and a mission.

Quests associated with puzzles provide rewards, so you'll need to complete all puzzles with the Quest sign available to get them all.

You can check the quests from Quests on the puzzle screen. Solve all puzzles in Round 4 to complete the associated quest and get Light's back. More information here.
