Email your solutions to andy.brown@puzzlemanic.com, there may be a prize for the best set of solutions received! Answer key: for each cell of the longest diagonal starting in the bottom left of each puzzle list the number of the cell that emits the signal crossing it.

Each number represents a mobile telephone mast. Your job is to adjust the signal strength in each direction so that the whole area is covered. Each number represents the total length of straight line signals starting from that number.

  • Standard
  • Triangular
  • Hexagonal

    • Standard

    A maximum of 4 possible signal directions: horizontal and vertical (no diagonals).

    Standard1 Standard2
    Target time < 5 minutes Target time 5-10 minutes
    Standard3 Standard4
    Target time 10-20 minutes Target time 10-20 minutes

    Triangular

    Similar to the standard puzzle, with a maximum of 6 possible directions (2 for each triangle edge, none at the corners), but a maximum of only 3 actual lines for each number (1 for each triangle edge). It should be easy!
    Triangle1 Triangle2
    Target time < 5 minutes Target time 5-10 minutes

    Hexagonal

    Same as the standard puzzle, but a maximum of 6 lines for each number. Harder than it looks!

    Hexagon1
    Target time 10-20 minutes
