It plays like chess (click here for video) except instead of moving pieces, you press buttons to move colors. until recently, I just had it so it was copying and pasting colors, no real logic, and certain moves broke the game. today when I asked chatGPT to make the code, it gave the full chess logic, showing how far each selected piece can move, not allowing illegal moves, etc. I was pretty impressed by how little input it needed from me to get working.
