Patterna is a logic puzzle game inspired by HexCells. Each level of the game consists of a network of nodes (a graph). It is your job to figure out which of these nodes are part of the pattern and which are not. To help you achieve this goal, each node may carry information that uses reachability, distance, or color to constrain which nodes are pattern nodes. Correctly classifying a node may reveal new information which in turn will help to solve the puzzle.
This is the demo version of Patterna for Linux. It includes the tutorial and three more difficult levels. The default version of the game assumes that OpenGL 3.0 is available on your system. If that is not the case or if you are having any kinds of graphical problems, add the '-force-opengl' parameter to use OpenGL 2.0.
