GRhino, or Rhino its former name, is an Othello/Reversi game. What distinguish GRhino from most other Othello games is that GRhino will be targeted for experienced Othello players. Strong AI is the main focus with some additional good, useful features (like an endgame solver) is planned. The ultimate target strength of the AI is that it should be able to beat the best human player at the highest difficulty level.
