Should I have repeatable questions or nonrepeatable questions in a mini-game show?

I hope to create 60 questions in a questions bank. I plan to create a nonmandatory game show location in which a player can pay to participate to win a prize and visit anytime.
5 random questions per participation.
The problem is here; I believe that nonrepeatable questions can be a little bit mean to a player, but at the same time, repeatable questions can be abused by a player. So do you do think the player has right to cheat?

Repeatable is fine as long as you don't foresee the player being able to break the game's economy through getting perfect scores at the game show over a reasonable number of repeated plays (once they know all the answers).

If they can break the game's economy, consider organizing the 60 questions into 12 "episodes" of 5 questions each, with each episode playable just once. You could even theme each episode for extra fun - You Don't Know Jack: The Ride is a fantastic example of a quiz game that does this, and the more modern YDKJ games loosely theme the episodes with running gags and callbacks as well.

Honestly, you could track questions the player has answered correctly and skip them the next time the player comes back. This way, it's the best of both worlds. Episodic questions are also great as @Wavelength has also suggested. Everybody's Golf did this but opened up episodes after the PC leveled up a bit. Something to think about!

Just keep in mind that, if you go with the "repeatable questions" route, it could end up feeling a little silly.

I've seen this before in both the Mega Man Battle Network and Mega Man Starforce series. They have optional quizes that can be beaten to obtain unique items. However, nothing stops you from retrying the quiz after making a mistake, and the quiz is exactly the same every time. Thus, the player can make it through any quiz just using trial and error. It doesn't require knowledge, but patience.

I'm a little unsure what you mean by "unrepeatable questions," though. Will a question only be able to be answered correctly once? Or will it be removed from the pool, whether or not the player gets the right answer?

But I like consolcwby's solution the most. Also keep in mind that you could just provide unique items, if you don't want to crash the economy.

@Wavelength, thank you for your inputs
@consolcwby, thank you for your insights
@Autofire , than you. unrepeatable questions mean if the player allows answering onetime per question and it never shows up again.
Remember, I use random variables from 1-12 questions, so if players want to write down the whole 60 questions. They can try.
Do everyone think that still abusable by a player?
@gstv87, thank you for your experience, so what are your propose I should do then?

I have a board game that consists of over 100 pages, double-sided, 8 questions each.
that's over 1600 questions.

I could probably quote a couple of them from memory

............... I haven't played that game in well over 20 years.

let that sink in.

I would give the player 5 choices per question instead of 4, just so it's harder to abuse them.

Both ways I see this working. My only thoughts are to make sure the player can get the right answers to there questions through the game by the time they take each quiz, otherwise warn them they aren't able to complete that particular quiz yet.

If your going to do nonrepetable questions, you can use a variable to pick certain random ones each time.

I would choose the "non-repeatable until exhausted" path, so questions cannot repeat until all 60 have been asked, where it resets. This works if your quiz is not frequently played, or it's not important. 60 is enough for this.

I mean, you can't really avoid hardcore players from remembering all 60 (I've seen people using excel to do so). Well, you could with 1600 questions... probably. It depends on how many times players try to answer.
