Aust10: IF wgt does take 10% off 90 credits then they are charging a 20% fee not 10%.
On the surface, that IS the way it looks( I thought the same thing a long time ago) ... but they aren't charging 20%.
Here's how you have to look at it ... as soon as that 100 credit wager is submitted & accepted, BOTH players have 10 credits ( 10% of the wager) deducted from their accounts. So the 100 credits will only be 90 awarded to the winner.. The loser's account will have 100cr deducted ... the 90 plus his 10% fee.
The winner's account has already had the 10cr deducted for his fee before ever hitting the first tee, So, you more or less start out at -10 credits ... add the 90 credits for the win and you have a net gain of 80 credits.
