that dice game

Five dice.  Winner is the first player to reach an agreed upon amount--often 5000, but we play until 10,000
-ones count for 100
-fives count for 50
-three of a kind count for 100 times the dots on one dice i.e 3 fours count as 400, three fives count as 500, except for 3 ones which count as 1000   A fourth one will only count as an extra 100.  This is the only time 2's, 3's or 6's can score.
-each player must roll 1000 or moer in one turn to open and start recording scores.
-each player keeps rolling until he rolls something without either a one or a five, in which case he looses everything.  To keep going, a  player must keep at least a  one or a five from each roll, and thereby roll fewer and fewer dice at each roll in his turn, until he has a one or five on all five dice, at which point he can start rolling all five.  This can keep going as long as there is a one or five on each roll.
-Once a player has opened, he can choose to stop rolling and keep whatever his score is at that time, on each turn.
-if a player stops without keeping score from all five dice, provided the next player has opened, he can take a regular turn OR he can then take whatever dice are left and roll only those dice.  If he scores a one or five he can keep going and thereby "steal" the same amount as the previous player had rolled and taken.  This player can continue rolling until he chooses to stop or makes a roll without a one or five, and looses it all.  "Stealing" can move around the table, getting bigger and bigger, until someone makes a roll without a one or five.

I know this sounds complicated, and I've gone into a lot of detail.  It is really a fun game, and it becomes quickly obvious why it's sometimes called "Oh shit"
