Fun Dice Game

I think it's called 'Greedy'.
You need: 10 dice; paper & pen
2 or more players

Here is the scoring:

1's -100
5's - 500

Three of the same number- that number X 100
each additional of the same number, double your score
(example three 4's gets 400, four 4's gets 800, five 4's get 1600 and so forth)

Three 1's - 1000 (double score for each additional 1)
Roll all 10 dice into pairs - 2000 plus roll again

How to play:

On your turn, roll all ten dice, put aside any dice that are worth points.
Roll the remaining dice if you want. Put aside any dice that are worth points.
You can roll as many times as you like, as long as you put dice aside.
If you roll and get no points, you lose all the points you accumulated on your turn.
If you roll, and use all the dice, you can continue to accumulate points by rolling all ten dice again, and putting aside as before. If you roll and get no points, you lose all your accumulated points on that turn. You may stop rolling at any time on your turn.
Write down your score. It's the next person's turn.

You can play to 15,000 (whatever you want). When someone reaches the total score of 15,000, each player gets one turn to beat that score to determine the winner.
