What do you call a game with 500,000,000,000,000,000,000 possible play positions? Checkers, of course. That's according to computer scientists who have succeeded in "solving" the well-known game for every possible smart move.
They found that in a perfectly played game, checkers is a draw.
The feat was accomplished by running checkers games on dozens of computers for 18 years, using cutting-edge artificial intelligence.
