In 2026, I still think back to the In the Sandbox web event for Zenless Zone Zero. It ran from March 17 to March 24, 2024, and for one week, Proxies like me could step into a playful personality test, invite friends, and earn Lucky Draw Tokens for a chance at an Amplifying Test Qualification. The game has long since launched, of course, but that small event remains a fond memory. It was simple, weird, and very Zenless.

The concept was straightforward. During the event, the sandbox presented different scenarios. I chose options that matched my situation, and the system explored my inner personality. I remember picking answers that felt honest—sometimes chaotic, sometimes practical—and laughing at the results. Then I invited a few friends to see whether our personality types went well together. Some did. Some definitely did not. 😂

Every completed mission gave me Lucky Draw Tokens. Those tokens were the key to the prize draw. I could use them for a chance to win Test Qualification, merchandise, and other rewards. The draw was exciting because the prizes were not just virtual. They included physical items that I could hold, plus an exclusive HoYoLAB avatar frame that would stay with my account permanently.

Here is a quick breakdown of the rewards I remember:

Reward	Type	Quantity
Zenless Zone Zero Amplifying Test Qualification	Virtual / Access	2,000
Rug - Bangboo Edition	Physical Merchandise	300
Finger Skateboard Charm - Bangboo Edition	Physical Merchandise	350
In the Sandbox Event-Exclusive HoYoLAB Avatar Frame	Virtual	Permanent

Each Proxy could only obtain the same reward once. That rule made sense, but it also made every token feel precious. I did not win the Amplifying Test Qualification. I did, however, earn the avatar frame, and I used it on HoYoLAB for a long time. It was a small badge of honor from a very strange sandbox.

If I had won the test qualification, I would have needed to complete pre-registration and fill out the sign-up survey before the deadline. The registration deadline was March 24, 2024, at 11:59 UTC+8. Even if I had submitted related info before, that survey was still required. The qualification would have been issued according to the contact info in that survey. Winners of physical merchandise also needed to provide delivery details quickly. Looking back, the process was a little demanding, but it was standard for a limited test.

The event had several additional notes that I still find useful to remember. First, the web event was for entertainment only. It had nothing to do with the actual content of the game. Second, the HoYoLAB avatar frame was sent to the HoYoLAB account bound to the participating HoYoverse account. There could be a delay in delivery. Third, the Amplifying Test was only open to users who were at least 16 years old. Anyone who did not meet the age requirement could not participate. Fourth, each user could only obtain one Amplifying Test Qualification. The same HoYoverse ID, same email, or same phone number were all considered the same user. Trading, transferring, or selling a Test Qualification could result in cancellation. Fifth, shipping restrictions differed around the globe, so prizes might vary between regions. Sixth, merchandise prizes could take up to 90 business days to begin shipping. Seventh, customs clearance, taxes, or other processes might be required during delivery. If delivery failed because those procedures were not completed, no compensation would be given. Eighth, any information collected during the event would be used only for logging into the HoYoverse account and participating in the event. Privacy was protected according to laws and regulations. Finally, anything not detailed in the event rules referred to the HoYoverse Terms of Service.

In 2026, the Amplifying Test is a thing of the past. Zenless Zone Zero is fully released, and new players may never know how it felt to wait for a test qualification. But the In the Sandbox event still stands out to me because it mixed personality quizzes with gacha-style rewards. It was not deep. It was not meant to be. It was just fun. And sometimes, that is enough.

I loved the Bangboo-themed merchandise. A rug? A finger skateboard charm? Those are exactly the kinds of weird, delightful items that fit the game's tone. I did not win them, but I know some Proxies did. I hope their rugs are still cozy and their finger skateboards still roll.

Would I participate again if a similar event returned? Absolutely. I would choose different answers, invite different friends, and collect more Lucky Draw Tokens. The sandbox may be closed now, but the memory remains. Dear Proxy, if you ever find an old event like this, take a moment to enjoy it. You never know what kind of personality you might uncover.
