Gridz - Piecing together these puzzling connections is sure to cause a surge of Grid glyph addiction. Click the right or left side of a glyph to rotate it in that direction. Glyphs can only be rotated when they are connected to a power source. The goal of the game is to connect every glyph to a power source without leaving any glyph pathways unconnected. While one glyph may sometimes have both blue and pink power running through it, these two color streams must never cross, or it will cause a power surge.
