Question on tickets for live shows

[tsumekaze_]

Thank you very much, you have been amazingly clear!
In my country it works as you said, not by ballot but by a 1st come 1st serve rule, so I am not used to this kind of system. It's confusing ahah.

Can I ask you one question though?
You said I can ballot more tickets per person depending on the show, but if I am going alone and let's say I want to try balloting for 4 tickets (to see if I can score a better place among the successful ones or just to be sure I get my ticket! I don't want to lose the ballot and end up without a ticket, is that possible?) and I "win" all of them, would I be required to pay for all of them, or can I just choose one and discard the others?
