 One way to solve games is brute force. Just try every possible combination. I would hope everyone in this room has solved tic-tac-tum. Connect 4 is somewhat more complex. Checkers, that's a 10 followed by 20 zeros if you don't know how that notation works. 20 zeros. Connect 4 was solved many years ago. There is an absolute solution to connect 4. Checkers was solved several years ago by some Canadians with some crazy computers. It took 19 years and 200 computers to figure out checkers. The solution to checkers is if you play perfectly, both players can guaranteeably force a draw. Chess is somewhat more complex. That's actually a rough estimate. We don't even know how many possible positions there are in chess. And go is a- What size go board is that? That is a 19 by 19 go board. Go will probably never be solved.
