From the box:
Holding on for dear life - A group of thugs stole a bunch of gold from corrupt crime lord in the next town over. Tonight is the secret meeting to decide how the gold is split. At this meeting each theif has their own sturdy moneybag. If someone thinks the gold distribution is unfair, they can call out another follow thief they believe has more gold coins and move some fo those coins from the other thief's bag to their own.
However, they must be very carefull if the thief steals too much gold and gets caught, they must give all of their coins to the other thief as punishment. This is an unusual game where you need to gauge how many coins the other players have by judging the weight of their moneybags and bravely accusing them of taking too much gold.
