On the 19th of May, 2009,
we were hatching

Luna: The goal was to create as many hatched areas as possible. It was very difficult to formulate the precise rules although I had it very clear in my head.

Initial setup

  1. Play with four players.
  2. Each player as a colored pen: red, green, blue and black.
  3. Each player places a dot on the sheet at an arbitrary position but not further than 10 cm from each other.
  4. The players take turns:

Task to be performed every turn by each player

Draw a straight line

  1. The line must connect two dots.
  2. The angle of the line must be within the following range: 0 to 45 degrees for the black lines, 45 to 90 degrees for the blue lines, 90 to 135 degrees for the red lines, 135 to 180 degrees for the green lines.
  3. Connect the line to an existing line if possible.
  4. Draw the shortest possible line from your starting point. If you enclose an area (a plane surrounded by lines) then hatch it with lines parallel to the line you enclosed the area with. The enclosed area may not contain unconnected dots or open ended lines.

Place a dot

The position of the dot is not further away than 10 cm from other dots and not inside the convex hull of all dots.
