Mercury Hg is a puzzle platformer video game developed by British studio Eiconic Games and published by UTV Ignition Games. It is the third entry in the Mercury series. The goal is to navigate a blob of mercury to a goalpost by tilting the stage without losing all of the mercury. The mercury can be split apart into multiple blobs, change colors using Paintshops, and be remerged into a new color. In addition, the game utilizes an online leaderboard, ghost sharing, and the ability to insert music into the levels.
