Fencer: Crazy.... I guess on Pogo, when you spend Gems, that is it they are spent. The same as here if we were just going to use Brains in the shop to buy a shirt or mug, that would be OK.

Surely there must be a way around this

It must come down to how they define the word gamble, and looking at dictionary.com it is only a gamble if there is a element of chance involved (i.e. Toss of a coin OR Roll of a Dice)...So if we stick to Chess & Go we are OK

all seems crazy to me
