Patterna

Here is an excerpt from Patterna's Steam description:

Patterna is a logic puzzle game for people who think that HexCells is far too easy. It features a highly customizable random level generator, a level editor, more than 70 levels, and an enchanting minimalist soundtrack by Alex Cottrell.

In Patterna, each level is a network of nodes (also known as a graph). In a way similar to HexCells or Minesweeper, each node is ultimately in one of two states (known as pattern and non-pattern). Initially, most nodes' states are unknown. It is the player's task to correctly classify these unrevealed nodes using information based on distance, connectivity, and color. Correctly classifying a node may reveal more information that in turn helps you to solve the level.

• More than 70 levels, plus a tutorial
• Procedurally generated levels with plenty of options for the level generator
• Enchanting minimalist original soundtrack by Alex Cottrell
• Absolutely no guessing needed
