Mastering the Brainiac Quiz: A Guide to Infinite Navigation Beacons in Zenless Zone Zero's Abyss
Master the Brainiac Quiz answers in Zenless Zone Zero's Abyss to secure crucial navigation beacons, a key resource for endless progression.
Deep within the shifting labyrinths of The Abyss in Zenless Zone Zero, a peculiar opportunity awaits the observant Proxy. Amidst the chaos and Hollow threats, a special event tile known as the Brainiac Quiz can appear, offering a seemingly simple challenge: answer a question correctly and earn a precious reward. There is no penalty for a wrong answer, but the prize—navigation beacons, the lifeblood of progression through this endless dungeon—makes this a chance no savvy explorer should pass up. For the clever player, this isn't just a trivia test; it's the key to building a self-sustaining economy of beacons, turning a single quiz into an endless fountain of resources. However, a word of caution: not all answers are found in a guide. Two of the questions probe your personal journey, demanding knowledge of your own inventory and progress, making preparation as crucial as recall.

The Eight Questions of Knowledge
To conquer the quiz and claim your beacons, you must be prepared for any of the eight possible questions. Here is the complete arsenal of answers you'll need to memorize.
1. The Puzzle of Soul Hounds III
The question takes you back to the arcade. "How many blocks of the same color do you need to make them disappear (in Soul Hounds III)?" The answer is a simple, satisfying number.
Answer: 4.

2. A Bite of Sixth Street Lore
Your knowledge of New Eridu's culinary scene is tested. "How much does the cheapest noodle bowl at Waterfall Soup on Sixth Street cost?" It's a staple for budget-conscious Proxies.
Answer: 1800 Dennies.

3. The Scarf of Random Play
Attention to detail is key. "What number is written on the scarf of the Bangboo at the counter (of Random Play)?" Next time you're browsing videos, take a closer look at the clerk.
Answer: 18.

4. Domo's Signature Sparkle
For the mixologists of New Eridu. "How many ml of sparkling water does it need (for Domo's signature drink)?" Precision is the soul of a good beverage.
Answer: 250ml.

5. The Viaduct's Limit
A practical question about city infrastructure. "Sixth Street is near the viaduct. What is the height limit for vehicles passing through under the viaduct?" Don't get your truck stuck!
Answer: 5m.

6. The Bookkeeping Bangboo
Another test of your observational skills in the convenience store. "Which Bangboo has a ledger on top of its head (at the Sixth Street convenience store)?" It's the one keeping the accounts.
Answer: Ask.

The Personal Challenges 🧐
Now, we arrive at the two questions that separate the prepared from the panicked. These answers are unique to you and cannot be looked up.
7. The Beacon Inventory Check
The game turns the mirror on you. "How many navigation beacons do you currently have?" When this question pops up, your current beacon count is hidden. You must check your inventory before activating the quiz tile! Make a mental note or write it down. There is no universal number here.

8. The Depths of Your Journey
A record of your personal ambition. "What is the deepest floor you have ever reached (of The Abyss)?" This tracks your all-time best, not your current floor. For newcomers starting the 'Infinite Abyss' Commission, if it's your very first time, your current floor is your deepest. Just look at the text on the top of your screen.

The Eternal Reward Strategy 💎
The true genius of the Brainiac Quiz lies not in a single correct answer, but in the sustainable loop it creates. For every question you answer correctly, you are rewarded with two navigation beacons. Consider the economics:
-
It costs one navigation beacon to pin a Brainiac Quiz tile and carry it to the next floor of The Abyss.
-
If you answer correctly on that next floor, you gain two beacons.
This creates a powerful cycle:
-
Find a Brainiac Quiz tile.
-
Spend 1 beacon to pin it.
-
Advance to the next floor.
-
Answer the question correctly (using this guide and your personal notes).
-
Receive 2 beacons as a reward.
-
Net Gain: +1 Beacon.
By repeating this process—always ensuring you have at least one Quiz tile pinned—you can generate a theoretically infinite supply of navigation beacons. This strategy transforms the Quiz from a minor event into a core progression engine, funding your exploration deeper into The Abyss than ever before.
