Asteria: Cosmic Drop & Merge

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.

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.
