An excellent PC version of the Mastermind board game
MasterDX is an excellent pc version of the classic puzzle game, Mastermind.
MasterDX has an excellent user interface, which looks exactly like the original board making it very clear and easy to see what’s going on.
The game is played the same way and rules are exactly the same as the proper Mastermind board game, except you must register for free first before you can use all the capabilities of MasterDX.
