The Infinite Abyss is a special Hollow that players get to visit in Zenless Zone Zero. The main goal here is to try and get as far down into the abyss as possible without getting fully corrupted. There are quite a few random events here, including the Brainiac Quiz.

This random event is as straightforward as it sounds. Players will be asked questions — get it right, and you'll earn the right to pass. If you get it wrong, well, the game will make you feel bad about yourself. It resembles the many random encounters in ZZZ's Hollow Zero, though it's much more contained within the Abyss' context. If you'd rather not deal with losing HP or risk increasing your Pressure meter, here are all the correct answers to the Brainiac Quiz questions.

The Brainiac Quiz randomly appears on each floor of the Infinite Abyss, the special Hollow that comes as part of the Eternal Bangboo Causes My Descent commission in ZZZ. If you didn't encounter the quiz during your initial trip to the Infinite Abyss, you may run into it in a future attempt. Each encounter will ask one question chosen from a pool of eight different questions.

Question

Answer

How many blocks of the same color [in Soul Hounds III] do you need to make them disappear?

4

How many navigation beacons do you currently have?

Depends on the player

What is the deepest [Infinite Abyss] floor you have ever reached?

Again, this depends on the player

[Sixth Street Convenience Store] Which Bangboo has a ledger on top of its head?

Ask

[Domo's signature drink recipe] How many ml of sparkling water does it need?

250ml

[Viaduct near Sixth Street] What is the height limit for vehicles passing under the viaduct?

5m

How much does the cheapest noodle bowl at Waterfall Soup on Sixth Street cost?

1800 Dennies

What number is written on the scarf of the Bangboo at Random Play's counter?

18

Players can replay the Infinite Abyss by going to the Chapter 3 - Exploration menu on the HDD.

There doesn't seem to be any real penalties to getting a Brainiac Quiz answer wrong. However, if you get one right, you'll get some Navigation Beacons, which are used to pin an event tile so that it appears on the next floor. With these, you can make sure you have Brainiac Quiz tiles on every floor as long as you don't forget to pin them.

For players who want Polychromes to buy Master Tapes in ZZZ, all you need to do is complete the original Infinite Abyss commission. Finishing all 99 floors doesn't reward you with much apart from Dennies and chests.
