The Mermaid Treasures event in Monopoly GO requires you to collect enough pickaxes to clear all the treasure grids, which can be tough.
To make things easier, prioritize participating in banner events and tournaments, as they reward you with hundreds of pickaxes, dice, and other goodies to help you progress.
Remember to claim your daily Quick Wins and free shop gifts for a few extra pickaxes if you're struggling to finish a level.
While there aren't any pickaxe links available right now, Scopely has released them in the past, so keep an eye out for any potential updates.
