Is this complicated rock-paper-scissors? It starts with someone able to win on the first turn by guessing a row/column that other people ignored. Then there's always one (maybe two) people who build up strength, but even they can be beaten if someone slips in a quick row somewhere else.
Looking at the standings, Jim is the only one who's managed a .500 record over the course of several games. Dzander and Sharkey have managed reasonable records in a multiplayer game.
But it just feels like throwing things around with zero control. What do others think?
