Points are derived from the dice in the following ways:

rolling a 5 is worth 50 points rolling a 1 is worth 100 points rolling 3 of the same number is worth 100 x n (3 5's is worth 500, 3 3's is worth 300, but 3 1's is worth 1000) rolling a straight (1-2-3-4-5) or (2-3-4-5-6) is worth 1500 rolling 5 of the same nubmer is worth 1000 x n (5 5's is worth 5,000, 5 3's is worth 3,000, but 5 1's is worth 10,000)If you roll and do not get any points you lose any points that you have accumulated this turn (i.e. the points that you have collected so far this turn are subtracted from your total score). If you use all five dice to generate points, you can through them all again. You may choose to stop rolling the dice and collect your points at any time.
