Reversi
The NeuralPlay Reversi AI sports a strong Artificial Neural Network. More conventional brute force methods applying game tree search to Reversi work well, however a well-trained neural network can offer better performance given cpu time and processing constraints. The limited processing power of a cell phone illustrates the advantages of a well-trained neural network over a brute-force approach.

Currently, NeuralPlay Reversi Free on android offers many fun and useful features, including
  • six computer levels varying from very easy to very difficult
  • human vs computer play
  • human vs human play
  • computer vs computer play
  • undo move
  • optional display of legal moves
  • optional display of last move played
  • play on 4x4 and 6x6 board sizes for learning
Can you beat the Neural Network?
