- Daily choice-based planet survival story
4worlds.io is a daily choice-based survival story. Four planets arrive each day, and you choose one to inhabit for a year. The game presents a chain of situations rather than a single fixed route: read what is happening, weigh the available responses and see whether your choices keep you alive through the year.
Different planets bring different challenges. Pool Town features a critical hot storm and choices about preparation; Honeycomb centers on oversized bees and a dangerous swarm response; Dry River warns of a rare upstream flood in a canyon settlement; and Wave Hill has a close-moon annual hazard. These are examples from the game’s worlds, while the daily selection changes.
You can revisit earlier planets through Past planets, but the keepsake reward is time-limited. Reach a planet’s best ending on its release day to earn its keepsake. The shelf displays collected items and provides a save code; collected keepsakes come in four rarity tiers: wood, silver, gold and shimmer. This gives repeat players a collection goal alongside the year-long survival challenge.

How to Play the 4 Worlds IO Game
Controls
Click Play Now above to start the game. Choose one of the four numbered planets shown on the opening screen, then read each situation and select a response. The goal is to survive a full year on the planet through the choices you make.
Each day introduces four new worlds. If you missed a release, open Past planets to play an earlier world. The available story, hazards and choices depend on the planet you select, so read the situation before choosing rather than expecting the same route every day.
A planet’s keepsake is tied to its release day: reach the best ending on that day to add it to your shelf. Past planets remain playable later, but their keepsake can no longer be earned. Use the shelf’s copyable save code to keep a backup of the keepsakes you have collected.

Frequently Asked Questions
Where can I play 4worlds.io?
Click Play Now above to start the game, then choose one of the four numbered planets on the title screen to begin its story.
What do you do on a planet?
Read each situation, choose a response and try to survive the full year. The story continues through daily events, and a planet’s hazards depend on its world.
Can I play planets from earlier days?
Yes. Use Past planets to open a previous world after its release day. You can still play its story, although its release-day keepsake is no longer available.
How do I earn a planet keepsake?
Reach the planet’s best ending on its own release day. The shelf can show keepsakes you have earned, but completing an old planet later does not award its keepsake.
What do the keepsake rarity labels mean?
The game lists four tiers: wood at 65%, silver at 26%, gold at 8% and shimmer at 1%. These labels describe keepsake rarity rather than survival difficulty.
