11. Any ticket for which payment by the player was not made prior to the draw for which it is valid, is void.
It is the same for any ticket that is illegible, mutilated, altered, counterfeited, improperly cut, misprinted, incomplete, erroneously printed or otherwise defective, unless it is possible by the control number to determine that the ticket is really a winning ticket.
The holder of an invalid ticket is not entitled to a prize.
