Pirates Dice

The goal of this game is to guess how many dices there are of a number, you pick and be the last one left with dices.

Rules:

You always have to raise (if you say 4 fours the next one will have to say 4 of anything more than 4 or 5 of anything)

Pirates count as 2 ( if someone says 8 fives you can say 4 Pirates, but if someone says 4 Pirates you will have to raise it and double it)

If someone only has one dice left you cant change the dice of the start bidding (if the first bid is 4 fives you have to say 5 fives or more)

If you dont believe the bid before you, you say raise ,the round stops and you count if you were right or not, if not you lose a stone, else the one before you loses a stone.
