For anyone interested, we have recently finished developing AI for Monopoly trained with Machine Learning.
Quadropoly
This is a AlphaGo / Deep Blue style project, but for Monopoly. For the first 16 months, AI was trained by playing against each other (4 player's games). Currently, full logs from games with top level AI are uploaded to the cloud for Machine Learning, so every good player ( >25% winrate) is helping to make AI better. AI has already invented several dozen effective strategies which has never been used before by humans. Less than 1% of players are having 25% winrate or higher playing with 3 AIs on top level difficulty. Game has no cheats in any form, AI does not know whether they trade with human or another AI, and treats every opponent equally on all difficulty settings. Game is 100% free for anyone with Android device, feel free to check it out.
