Let's be careful with the term "computer". Back in the 50's Bell labs built a tic-tac-toe "computer" from relays, they had one at the old Buhl Planetarium in Pittsburgh. The game of tic-tac-toe is easily simulated with a finite state machine (FSM) as there are fixed strategies, clear outcomes and lots of symmetry. The  project requires the development of a flip-flop, or memory device, so that your machine can remember what the current state of the game is--that will determine what it's move will be. You also need a representation system and logic gates, but these are relatively easy after the flip-flop problem is resolved.

Browse http://www.rustrans.co.uk/rope.html for a description of a "rope and pulley" computer, it might give some insight into building one with Lego.
