In the Sea Shell event, you need to beat regular match-3 levels on the first try and all in one go. This event becomes available to you at Level 23 and above. There are three shells in the event, each containing more boosters than the last.

For every level you beat, you’ll receive free boosters at the start of the next level. The more levels you complete without losing, the more boosters you’ll earn. However, if you lose, you’ll lose all your saved rewards and have to start over, so be careful.

PLEASE NOTE

🌊 The event is only available on regular match-3 levels and Atlantis League levels.
🌊 You need to beat 1 level to unlock the first shell, 2 levels for the second shell, and 3 levels for the final shell. Once you reach the last shell, you’ll keep getting boosters from it until you lose a level.
🌊 If you enter a level but exit without making any moves, you won’t lose all your progress. Instead, you’ll drop down one shell level (for example, from the third to the second shell), keeping some of your rewards but with a small penalty.
