Eliot is an open source Scrabble game, freely available under the GNU GPL license.
Eliot offers four different game modes:
The free game mode is the standard one, ideal for having fun with your friends or family. The players play in turn on the board, each with his own rack.
In the duplicate mode, all the players are faced with the same board and letters at the same time.
The training mode allows to play alone and make progress for the duplicate. It gives more freedom than the multiplayer modes.
The arbitration mode lets you arbitrate very efficiently a duplicate game, possibly with an important number of players.
Feel free to make feature requests or to report bugs: feedback is welcome!
