Much of this educator’s work concerns a mixture of logic with educated guesses. This educator teaches a class called Heuristic Problem Solving in which students face puzzles every week and write computer programs to solve them. Some of those students have turned those puzzles into two or more people computer games. A few of those games even include an Artificially Intelligent opponent.

Please visit the doctor ecco site to create an account and try the games. The Gravitational Voronoi, No Tipping, and Pandemic games might be a good place to start. Give them a try and see how you do.
