Help grid base

wt96311

Hello community, I am fairly new to gamesalad and just recently got stuck half way through building my first game. I have 6 by 6 grid and I am trying to figure out how can I make limited movement to only 4 squares every selection. It is almost like a Minesweeper type game except , when you pick a square on the grid and it flips over the next square you are able to select must be two spaces away in all four directions. I have all the select squares and stuff down but just cant figure out how to limit the next choices after .

Happy New Year! Keep in mind that the methods I used in the attached file are somewhat complicated so it may require reading up on or watching videos related to tables, etc. before it all makes sense.
