## What is Asteria?

Drop two of a kind and they fuse into something bigger. Asteria takes that puzzle out of the jar and plays it inside a gravity well.

Sling celestial matter at a dense core and watch it fall into a slowly turning accretion disk. Two specks of dust make a meteoroid, two meteoroids make a comet, and nine more rungs climb from there. You choose one thing — where to launch. Gravity decides the rest.

GRAVITY IS THE PUZZLE
No jar and no grid. The core pulls everything inward and the disk turns as it grows, so the board you aimed at is never quite the board you hit. One well-placed merge cascades through the whole thing. A run lasts a couple of minutes and ends two ways: let the disk spill past the event ring, or fling a body clean out of orbit.

NO TWO SKIES ALIKE
Every body is generated from its own seed — the craters, the continents, the gas bands, the ring. Nobody else's sky looks like yours, and neither does your last run. It starts with a speck of dust; twelve rungs later, the disk is bending around what you built.

88 REAL CONSTELLATIONS
Chain deep merges and you chart the sky. Every constellation the International Astronomical Union recognises is in here — all 88 of them, from Orion to ones you have never heard of — and the deeper the chain, the rarer the sky it reveals. Every body, constellation and piece of debris you meet is logged in the Codex with a real astronomy fact. Rarity runs from Common to Mythic, and the mythic ones are hard to find on purpose.

FOUR BOOSTERS, EARNED BY PLAYING
Never sold.

• Accretion: grows the drop in your hand, up to three rungs.
• Antimatter: annihilates trash and the smallest bodies where it goes off.
• Dark Energy: shoves the whole disk outward and hands it back rearranged.
• Gravity Assist: swings your drop around the ring to a partner it could not have reached.

SPACE TRASH AND SCRAP TRADERS
A dead satellite never merges — not even with more trash. It wedges into the disk and stays there, so you either thread it past your own clutter and into the star or build the run around it. Either way, it is a problem with a solution.

And every few minutes, one of the solutions crosses the sky. A scrap trader's ship comes out over the disk, turns at the far edge and comes back to make you an offer: booster charges, or a salvage run that hauls every piece of junk off the board at once. Answering is a rewarded video and always your call — ignore it and it leaves, and another comes by later.

A REASON TO COME BACK
A new challenge every day restocks your boosters. 35 achievements to unlock and four leaderboards to climb.

NO SIGN-UP, NO ACCOUNT
No account form. No email address. Open it and play.

THE SUPERNOVA EDITION
One purchase, once — not a subscription, nothing recurring, nothing to cancel. It removes the ad banners, quadruples what every booster holds, and raises every booster reward — and from time to time a scrap trader hands the cargo over free, with no video at all. The rewarded videos stay optional either way, because those are yours to choose.

## Version history (last 5 releases)

### 1.6.0 — 2026-09-07

Finish one of the day's challenges and you will know. A ring of gold leaves the challenges button, and a tab slides out from under it carrying the booster you just earned.

Collecting it is worth watching too. A finished challenge stays quiet until you take its reward — and the moment you do, light spreads out across the whole card.

Plus repairs to the notification card, which could leave you with no way out of it.

### 1.5.0 — 2026-09-03

A run you walk away from waits for you. Home says RESUME while one is unfinished, and takes you back to the disk you left.

Every new world is an occasion. The first moon, the first rocky planet, the first living world — each throws confetti in its own colors and sends a wave through the stars, every run.

And Asteria can reach you when you are not playing. It asks once, when you build a living world, and takes no for an answer.

### 1.4.0 — 2026-08-31

The Veil is no longer only a sky.

Every few drops a wave crosses it and marks two of your bodies. Three drops later both break at once: one climbs a rung, the other falls one. Both marks look the same until they break.

The game teaches the ladder now, too: from your first comet it names the pair worth merging next, and plays it out without giving away what it makes.

Ember is the last universe now, and Asteria runs on iPad.

### 1.3.1 — 2026-08-28

This one is all repairs.

If the app ever hung on the starfield and never reached the game, that should be over: every step of the launch now gives up instead of waiting forever, and one that fails tries again on its own.

And if it lost your session, it now says so, offers a retry, and reconnects by itself when your network comes back.

### 1.3.0 — 2026-08-26

The Rim and Ember play by rules of their own now.

On the Rim, frost takes a settled body and seals it in ice: three drops' warning, then no merging until the shell breaks. Well-aimed space trash breaks it, and scores.

In Ember, the dying star burns whatever rests against it. Let it finish and the body falls a rung; knock it clear and the save scores.

Runs are shorter, and tablets draw the system at a readable size.
