Rotate tiles to connect every node back to the server. A free logic puzzle —no downloads, no signup. Choose your language.
A network puzzle you can solve by reasoning
Every Netwalk board begins as one complete network. The tiles are then rotated, breaking the connections between the server and the other nodes. Your task is to turn the tiles back into a connected system. Cyan pipes show the part of the network that currently reaches the server, so each move gives you useful feedback instead of asking you to guess.
Boards are generated from a connected network, then checked before play. That means a puzzle always has a route back to a solved state. Begin with a small grid to learn the tile shapes, then increase the board size when you want more constraints to keep in mind.
How a round works
- Look at the corners and edges first. A pipe cannot lead off the board in the standard mode.
- Use the server glow to inspect current connectivity; confirm each move with matching openings and boundary constraints.
- When a route creates a dead end or isolates a group of tiles, rotate the last uncertain piece and test the alternative.
There is no time limit. You can use undo to test an idea, reset a board whenever you want, or work through the same Daily Challenge as other players. The game also supports custom board sizes, so a quick five-minute warm-up and a longer logic session use the same clear rules.
Learn the system, then choose your challenge
Netwalk is built around the rules of graph connectivity: every active node needs a path to the server, while loops and dangling pipes reveal a contradiction. The guides below explain those ideas in practical terms, including why certain corner moves are forced and how to scan a larger board without losing track of the network.
