We've got used to the idea of computers being able to beat  humans at games of skill, but now scientists have run computer simulations that reproduce every possible move in checkers – and discovered that the perfect outcome is a draw. 

Scientists at the University of Alberta developed the computer program Chinook, which has spent more than 18 years playing out the 500-billion possible moves in a game.
And the results of this exhaustive research reveal that the outcome of a perfect game is a draw, something experts have believed may be the case for years.
According to the scientists, checkers is the most complex game ever to have been solved by a computer, with every move being played out.
