What is TunnelLogic?

TunnelLogic is a daily logic puzzle game on Reddit. Your goal is to draw one continuous tunnel from the start tile (S) to the goal tile (G) while matching all row and column clues.

The game includes multiple difficulty levels (for example Easy, Medium, and Hard). Higher levels unlock after completing the previous one.

How the Game Works

• Build a single connected tunnel from S to G.
• The numbers on the edges show how many tunnel tiles belong in each row and column.
• Invalid rows or columns are highlighted visually.
• You can use hints if you get stuck.
