Every level starts with a dropper that introduces an element into the world — water, plasma, laser light or some mix of all of them. These elements are then guided, through the use of a predetermined set of items, to a tank that must be filled to capacity before the level is successfully completed. The tanks slowly lose their contents if not actively filling, which means the player must find a reliable solution to finish the puzzle and rely less on flukes.
The biggest new addition is the use of a full three-dimensional space in which to solve puzzles. In order to finish levels, players must rotate the provided items on all three axes to achieve the correct angle.
Players can also create their own levels to share with friends.
