Each tower will have huge food and alcohol stockpiles and nine dining rooms of equal value. You use an alternating switch such that when one dwarf enters a dining room the other is ejected from and locked out of his via drawbridges. Each dining room corresponds to a 3x3 or 5x5 square elsewhere filled with floodgates rigged to trigger in an X or O pattern, tied to a pressure plate the dwarf can't avoid touching if they enter the room. This pressure plate will also start a water-timer. Once this timer expires, the dwarf is ejected, again using the drawbridge-chain method, and the room is locked until the timer is re-primed, as is the corresponding dining room in the alternate tower. In this way, the dwarves must take turns and choose a square that is not actually taken. You have a final dwarf serve as judge with two levers and a stockpile of food and beer. When one dwarf wins, you have him pull the lever that floods the other's chambers. This will only require about a hundred perfectly-timed mechanisms. But the game supports it as possible.
