Mastermind is a great indoor game and is a great game for invoking the battle of the brains among friends. A great game to play with friends and family anywhere and at any time, Mastermind is also a popular online game. People who stay alone or are unable to find a competitor of their level to play mastermind with them often log onto online resources to find competition or play against the computer itself.

Offline, mastermind is a great game to be playing while traveling, dining or just gossiping. If you have a compatriot who is willing to play, you can use mastermind to kill time and hone your logical skills just about anywhere. Even if you do not have a player to play against, you can practice various patterns and their code breaking techniques on your own in order to use these cases while playing an actual game against an opponent.

Www.T45.com is a great online repository to play mastermind. The site offers a download-able version of the game, which you can download and play on your own computer while working offline. The game offers a human vs computer mode of gameplay while you are offline and also has the option of a human vs. human gameplay when you are connected to the internet. The game offers great visual graphics (although you wouldn’t need many while playing mastermind) and the computer offers three levels of difficulty. Therefore, you can choose the option that suits your gameplay the best and then gradually move upward towards higher levels of difficulty.

http://www.mah-jongg.ch/mastermind/ is another great online source of computer versions of the game. The level of difficulty with this station is pretty high and it offers only a human vs computer format. This site, therefore is great for those willing to play the game at an altogether high level of expertise and are ready to storm their brains for hours against the well designed computer player. The site also offers links to some other games, if you happen to get too stressed out while playing mastermind.

Another site offering great mastermind games and additional goodies is http://www.onlinegames.net/games/956/master-mind.html. You can join the site for free and the best part is that for every game you play, the admins give you one point. Once you have accumulated a specific number of points, you are entitled to getting them exchanged for goodies. The number of points and the prizes that you would be entitled to might vary from offer to offer, but the prizes are good and interesting. Besides, you get a point irrespective of whether you win or loose- just like a consolation or ‘participation’ prize.

One of the most interactive mastermind game sites that I have come across is http://www.blitzgamer.com/play_games/strategy/634/mastermind.html. The site offers a chat feature, using which, you can interact with fellow players on a real time basis. Such interactive features help in making the game more interesting and appealing to those who want something more than just serious gameplay from their games.
