Agar.io Mystery Potions

Mystery Potions is a feature that allows the players to collect Potions by playing that need to be “brewed” for some time before having access to its content. Inside, there are coins, parts of skins, and trophies to collect. The trophies are directly linked to the Weekly Leaderboards and how high the players rank on them.
