Summary of major new work completed in this new version:

4 years after the original release of Spades Free, we are happy to announce the single greatest improvement in play quality, after a prolonged dedicated period devoted to just Spades. This has always been a collaborative project shared with York University and has combined the best of AI research with game industry engineering to achieve the best result. In this last period particular attention was paid to the Nil game and partner play, but we also made substantial progress in the Joker variants and efficiency of the analysis. The end product was worth it. Discover the updated play for yourself!

We have now run extensive tests and for regular Spades rules the new version wins points an impressive 62% faster than the October 2014 version, so wins almost all games. For Barmore rules this advance in points win rate is an astounding 217% faster. To get this big jump in performance we took some ideas from the World Champion Go program AlphaGo, which recently beat the human world champion for what is considered the world’s hardest game. Bidding now includes a new hybrid bidding system that allows Spades to make much better high bids.

We are looking to add more great features and game variants for Spades Free. Watch this space!
