Please help me to understand how to enact the game end:
1) All shares are sold at current market value: i.e freeze the prices and all players sells their shares at the current value with no adjustment of value ?
The game can only end by a price adjustment, because this is the only way to have the silver price going to 100. So after this final adjusment, you just sell all shares at the current price as a final cash-in.
I hope this is clear.
