People like gaming because it is uncertain so everyone could be the winner. Of course, gaming needs luck, but not only luck, to be the winner, you need great mind too. Mastermind is a puzzle game on www.flash-game.net in which your mission is to guess the color sequence and the order in ten goes. You just drag the colored balls into the spots, and then the computer will tell you the result. Black means you have got the right colored ball but placed it to the wrong position. White means you have put the right colored ball to the right place. So after some reasoning, you may find out the right color and order. Good luck!
