Terms & Conditions
Objective / Rules - Unscramble and complete the network. - The completed puzzle is a single network of computers, without any loops. - Every computer is connected to every other computer and every square is used in the network.
Help Read the help/walkthrough page on Network puzzles for a more detailed explanation and a walkthrough.
Wrap vs No Wrap Wrap means the network can wrap off the edge of the grid (i.e. right to left, bottom to top, etc). Easier puzzles have No Wrap, and the border to the puzzle is red.
Mouse & Keyboard Usage Left-click = rotate counter-clockwise. Right-click = rotate clockwise. Space key = lock the square the mouse is over (very useful if you're sure a square is correct).
Checking If you click 'Check' the system will check the current state of the network. However, the system will only check squares that are locked. If 'Show mistakes when checking' is checked they will be marked in red.
Uniqueness Each puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules.
