Will you go from bottom to top in the first grid? Or go across starting from the top left? With the second grid, will you start on the left and go clockwise? Or start on the bottom and go counterclockwise? I have created this code starting at the top left for the first grid and going down, then back up to the top middle, etc. You need to have determined ahead of time, with your secret message pen pal, how you will arrange the letters. Then fill the grids with letters of the alphabet. You just need to draw the four grids, adding dots to the compartments of the last two grids.
