Tic Tac Toe Extended RMX

With great respect to Thomas and his work done.

1. Supplemented the chips with a marking on top. This can now be printed in one color. It will also allow people with visual impairment to play.
2. I changed the case because I couldn't tighten the lid in the original.

The playing field - "G" remained unchanged, but for convenience, I also included it in the distribution.
