Yahtzee in minecraft is completely automatic and only requires you to push some buttons. Start by rolling the dice. When the dice appear, hold selected dice to try and get three of kinds, straight, full houses, etc. The game will automatically tell you what score possibilities are possible by indicating a blinking light. Once you have used up all three rolls, select the option that will get you the most points. The game autmatically keeps track of your points for the current game and your high score from  previous games. Not happy with the how the game is going? Hit "new game" and have a fresh game ready to be played in seconds.
