I have a suggestion for these types of tickets that will give players more choices:
Allow the recipient to buy into ANY NON-CASH poker game that has a lower buy-in value or lower fee with the understanding that any amount on the ticket that goes unused in said buy-in will be forfeit. This would allow players with say a 10+1 ticket to buy in to a 10+.50 game or a 20+2 to buy into a 15+1.50 game.
Better yet just make them $11, $22, $33 dollar tickets that allow you to buy in to any poker non-cash game up to that amount - with any overage NOT SPENT TO BE FORFEITED.
One Ticket, One Game, No Change.
