so if i understand correctly, you want equal to or more than what you put in???

so if you put $100 into a slot machine, play it down to $60, print out the voucher, in your case, say print out 6 $10 vouchers, you then want to sell those $10 vouchers for more than $10 because you didn't initially win at least $100? you can't. same with the strikes - if no one wants to pay more than $10 - you have to sell it for what you could turn in it at the cashier/cage for

sorry if i misunderstood your question
