HoYoverse Opens Stardrift Test Sign-Ups for Cozy Sim Petit Planet

Sign-ups for the Stardrift Test, HoYoverse's second closed beta for cozy galactic life sim Petit Planet, are live now, with the test itself kicking off on April 21. The studio has not announced a sign-up deadline, which means the window could close without warning. Registering immediately is the safest play.

This is the most accessible Petit Planet test to date. The first closed beta, called the "Coziness Test," launched November 7, 2025, ran only on PC and iOS, and was restricted to select regions. The Stardrift Test opens to PC, iOS, and Android simultaneously, putting the game in front of the full cross-platform audience HoYoverse is building toward for launch.

Getting in requires a HoYoverse account. Head to planet.hoyoverse.com, click "Pre-Register & Join Beta," log in, then complete the beta test survey covering your platform preferences and gaming habits. The survey runs roughly five minutes. After submitting, all that remains is waiting: selected players receive download instructions and test access via email. HoYoverse ran the Coziness Test in staggered invite waves, sending batches gradually rather than all at once, so if April 21 arrives without an email, more invites may still follow. Players who do not get selected can pre-register on the same page to receive a notification at launch.

Selection is competitive by design. HoYoverse's closed betas for Genshin Impact, Honkai: Star Rail, and Zenless Zone Zero all operated with limited slots and no disclosed acceptance rates. Completing the survey thoroughly, particularly the platform and daily playtime fields, is the only real lever applicants can pull.

For anyone who gets in, Petit Planet casts players as Planet Tenders. The daily loop covers farming, fishing, cooking, and decorating a personal planet, with a personal vehicle available for Starsea Voyage exploration. The Stardrift Test targets three systems specifically: expanded Neighbor interactions, enhanced Starsea Voyage mechanics, and new Galactic Bazaar activities. These are the exact areas the studio is seeking tester feedback on, which makes them the right places to spend time.

The Galactic Bazaar warrants the closest scrutiny. HoYoverse built Genshin Impact into one of mobile gaming's highest-grossing live services through gacha, and Petit Planet, as a confirmed free-to-play title, will carry some monetization layer. How the Bazaar handles transactions, whether premium currency surfaces during beta, and how aggressively spending gets incentivized will reveal a great deal about the final product's design priorities.

Mid-range Android users joining a Petit Planet beta for the first time should track frame rates under load, planet transition times, and Galactic Bazaar multiplayer stability. The game's entire pitch rests on a calm, uninterrupted atmosphere; performance hiccups undercut that identity directly.

The Stardrift Test also supports seven text languages and three full voice tracks. For a closed beta, that is an unusually deep localization commitment, and it signals that HoYoverse is treating Petit Planet as a global simultaneous release rather than a phased regional rollout.
