Wetrix is a 3D puzzle video game developed by Zed Two, the studio of brothers Ste and John Pickford. The player's goal is to hold water bubbles falling on a 3D isometric landscape. To do this, enclosures are created with Uppers, which fall in a similar manner to Tetris blocks, that raise the ground. While water can be evaporated with fireballs, hazards such as Mines, Ice Cubes, and earthquakes also fall and ruin the player's construction.
