Hello everybody !

Today i show you a Tic-Tac-Toe with an Artificial Intelligence (AI) and a Win Detector (WD).
It's a really compact design made by me with only redstone dust, redstone torch and repeaters.

This redstone device can run in 1.6.4 and over.

USER Guide:

Step 1 - Press button "C" (in the orange stained clay part).

Step 2 - Select the limit score (3-5-7-9 Pts) (in the black stained clay part).

Step 3 - Select the mod and the difficulty: (in the lime stained clay part).
                      - Solo Mod: -> EASY -> Select "E" button.
                                           -> HARD -> Select "H" button.
                      - Multi Mod: -> P(+) vs (PO) -> Don't select anything.

Step 4 - Select the first player, P(+) or P(O). In the Solo Mod, P(+) = AI = Bot (in the lime stained clay part).
WARNING: If you select the Solo Mod, choose P(O) (=you).

Step 5 - Play with the control button (in the red stained clay part).

If you want to:
- stop the match, press "R" (in the lime stained clay part).
- see your score, look the blue and brown stained clay part.
- see who is the winner, look the white stained clay part.

Enjoy,
