As with any puzzle game that offers a style of play you haven’t seen before, describing it can be a little tricky. A level of GEOM
consists of a field of varying colored line segments, all connected to each other’s endpoints by grey joints. Ultimately in any given stage there are three recognizable shapes on the field: triangles, squares, and hexagons. The player can click on any of these to rotate them clockwise or counter-clockwise.
The object of the game is to have the lines that make up a given shape be all the same color. Since many of the lines can be part of one or more shapes, this is accomplished by rotating the shapes so that you can move a given line segment around the board. When you succeed in having a shape be a uniform color, these identically colored line segments are replaced with random colors and you score points. Complete shapes fast enough in a row and you can score extra combo points.
As an added twist, bonus objects sometimes appear inside squares and hexagons for a short amount of time. If you can complete that shape before the powerup vanishes, you can get things like extra points, time or explosive effects.
