Sim Remix

The elegant pencil-and-paper game from Ramsey theory, you (red) versus a minimax CPU (blue). Six dots sit in a hexagon with all fifteen connecting lines drawn faintly. Take turns claiming a line in your colour — but the instant you complete a triangle of three dots all joined in your colour, you lose. The twist: a draw is mathematically impossible (Ramsey's theorem, R(3,3)=6), so once the lines fill up someone must crack. Force the CPU to make the first triangle.
