I started, you can find it, simulations called "Lights Out!"

Not done yet, of course. And the circuitry's way too messy, but I'll fix that once I get the right idea down.

Just uploaded to give you an idea, ask me for any clarifications.

EDIT: The winning part will be pretty hard, of course. My theory is to use a 25-way and gate (or how ever many boxes there are) and a not gate, so it lights up when all of them are not active. Thing is, we might need a switch for each gate so we can keep the and gate active, and that would require another circuit from each square. Could be doable with PTCT or NTCT though, I guess.

EDIT2: Done with the 3x3, as neat as I can make it. I'm working on an input system now, since finding the PTCT in the middle of the LCRY would be too hard for actual gameplay. For the final version, the LCRY will be very big, though (but I'll still have the input system because either 1) the PTCT would still be too small or 2)half the LCRY would be gone in favor of the PTCT)

I'm doing the inputter, but I think it's impossible to do it for the middle one as no semiconductor or metal is completely resistant to PTCT (both PTCT > metal and metal > PTCT). Tell me if you have any ideas

EDIT: Wow. I just played the game again and I've been doing it wrong - It's supposed to toggle the one you click and toggle all the one's adjacent. What I've been doing is just turn all the adjacent ones on.

I'll see what I can do, but no guarantees

I think you will need the processor of the other saves lol
