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.
