AlphaGo played very strongly in a desperate ko fight by Lee Sedol to take AlphaGo's big territory and thus win the third game of the Google DeepMind Challenge Match.
This means AlphaGo won the match with two games left to play.
Charities will benefit from the $1,000,000 prize.
Some more detailed commentary and pictures were available on the GoGameGuru website.
