You score the total of all the dice .\n\nA small straight is 4 consecutive die faces, and a large straight 5 consecutive die faces.Small straights score 30 and a large 40 points.\n\nAnd Yahtzee is 5 of a kind and scores 50 points\n\n\t\t\t\t How to   Play\n\nIn order to keep dice, you must enter a number from 1 - 5 which   match the dice accordingly.\n\ni.e. If you rolled (5,2,4,1,5) and you   wanted to keep the 2,4, and 1, you must enter \"2,3,4\"\n\nWould you like to start now?
