Mercury Hg is a puzzle arcade game developed by British studio Eiconic Games, released in 2011 for PlayStation 3 and Xbox 360. The third entry in the Mercury series, it tasks players with guiding a liquid mercury blob across tilting stages toward a goal without losing too much of the substance along the way. Stages can be manipulated to split the mercury into separate blobs, which can then pass through color-changing Paintshops and be recombined to produce new colors — a mechanic central to solving the game's puzzles. Beyond the core stage challenges, Mercury Hg supports online leaderboards and ghost sharing for competitive play, and also allows players to insert their own music into levels. The combination of physics-based movement, color-mixing logic, and social features distinguishes it within the puzzle genre.
