### LUX method of John Horton Conway

Use the Medjig method without puzzling. This method is known as the LUX method of John Horton Conway. The three letters are three different Medjig tiles. If you draw imaginary lines between the 1, 2, 3 and 4, you get the L (red marked), the U (yellow marked) or the X (blew marked).

First grid is filled with the LUX tiles. Second grid is a 2x2 'blown up' 7x7 magic square.

Take 1x number from first grid and add 4x [number -/- 1] from the same cell of the second grid.
