Hi, FPGA Oberon is certainly not a famous gaming platform, but I wish to port MasterMind game, the sources I took from other Oberons. `MasterMind.Mod' `MasterMindG.Mod' G-variant offers a computer solution, that I am more interested in. I have read some articles on Surreal Numbers and combinatorial games, I I only half understood. I learnt for some games a winning strategy exists, the one I experimented with is `Marienbad', reduced variant of `Go'. Now back to MasterMind, looking for some analogy and strategies. I can imagine a solution criteria can be based on minimum number of guesses. But I prefer simplicity, so just a solution, even non-optimal one but simple may be better for clarity. Looking into the code, I need help in understanding the strategy used there. It might be also interesting, to see, if a solution can exist in the domain of Surreal Numbers. I am not maths talent, but hoping this may caught some attention of mathematical minded people here. Can anyone please help? -- Tomas Kral <thomas.kral@email.cz>
