Scan the code with the Enjin Wallet app, pick your account and approve. This only proves the wallet is yours: nothing is signed or spent.
Your progress then follows your wallet to any device. If this device is further along than the wallet’s save, this device’s progress is kept. Nucleo NFTs in the wallet give in-game bonuses.
Every tick, your atoms release energy. Tap Excite to push the tick forward faster.
Spend energy to synthesize atoms of an element. Each synthesized atom also creates atoms of the element below it, so the whole chain grows.
Elements appear in order of how common they are in Earth's crust, then the synthetic ones. Every element you collect multiplies all energy ×1.25, forever.
Every 25 atoms you synthesize of one element double its output.
Lab upgrades cost energy and reset on supernova. Each level gives an isotope; spend isotopes on permanent upgrades that you keep forever. Changed your mind? Refund isotopes in the Lab gives them all back, free.
When the orb next to Supernova glows, tap it to capture a burst of energy. The Particle trap (Lab, permanent) catches them for you.
Once a cycle has released 10 billion J, collapse it for stardust, a permanent multiplier. Energy, atoms and Lab upgrades reset; your collection, level and isotopes stay.
At 20 elements, trade stardust for neutrons, an even stronger multiplier. Your first kilonova unlocks Autosynthesis.
Build real moons, planets and comets from surplus atoms, the extra atoms your chain makes. Each build gives a bonus and costs more than the last, with no limit. Builds reset on supernova, but the first build of each object catalogs it: all energy ×1.1 forever.
Later, under Cosmos → Neighborhood, build real stars, a pulsar and a black hole. They are permanent and cost stardust or neutrons as well as atoms, so each build is a trade-off.
Very late, big kilonovas (about 10¹⁸ neutrons) also condense dark matter. Spend it under Cosmos → Deep Sky on nebulae, star clusters and galaxies. They are permanent, and each one you catalog reveals the next.
You keep earning energy while away, up to 8 h (Half-life raises it); claim it when you return. Autosynthesis only runs while the game is open. Cosmic age grows with time played and slowly boosts everything.
119 goals across the whole game, under Profile → Achievements. Each one adds +2% to all energy, forever.
Profile has three small research goals every day. Each one pays out 5 minutes of energy. Finish all three to grow your streak: +3% all energy for each day in a row, up to +21%. Skip a day and the streak starts over.
Achievements unlock titles, shown under your name on the leaderboard, and background themes. Pick them under Profile → Style.
Under Lab → Probes, send probes to worlds you’ve cataloged for 30 minutes, 2 hours or 8 hours. They keep flying while you’re away and bring back real specimens: meteorites, stardust grains, planetary samples and comet material. Each kind multiplies all energy ×1.02 and each full set adds a bonus. Comets, supernovas and cosmic rays can drop specimens too.
Under Lab → Spectra, name elements from their real spectral lines: six stars a session, then the telescope recharges for 10 minutes if you got at least one right. Each correct answer speeds up ticks by 5% for 10 minutes of play (×1.4 for a perfect run). Harder observations unlock as you progress: look-alikes, moving stars, starlight and mixtures. Identified elements fill the Spectra collection; a complete family adds +10% to its output for good.
Every element earns up to five stars for how many you synthesize over your whole game (100, 1,000, 10,000, 100,000 and a million). Stars never reset, and each one multiplies that element’s output ×1.1.
Under Lab → Chemistry, combine surplus atoms into 49 real molecules, from water to xenon hexafluoroplatinate. Molecules are yours forever: each multiplies all energy ×1.03, and each of the seven completed sets adds its own bonus. Read about them in the Catalog.
Every Halloween, ghost particles (neutrinos) drift across the screen while you play: tap them, or press G, for energy and a neutrino, up to 5 a day. Some are tricks. Spend neutrinos under Cosmos → Haunted to catalog five real spooky objects, each with a permanent bonus. Catalog all five for the Witch Head Nebula card, claimable in Profile → NFT Drops until November 10, while codes last. You can preview the event from mid-September.
Every so often while you play, a comet streaks across the screen: tap it (or press C) for a big burst of energy. A meteor shower brings cosmic rays twice as often for 10 minutes, and a solar flare makes Excite twice as strong for 5 minutes.
Playing as a guest? Under Profile → Backup code, create a code and enter it on another device (such as a computer) to continue there. The backup updates by itself while you play.
On a computer: 1–5 switch sections, E excites and R captures a cosmic ray.
Under Profile → Ranks: players ranked by elements collected, then objects cataloged, then lifetime energy. Set your name under Profile.
Under Profile → Catalog: facts about every element, celestial object and phenomenon you have discovered. Tap an element in your collection to read about it.
Under Cosmos → Projects: every player builds the same structure together, one at a time. Contributors get a permanent bonus and NFT rewards in their Enjin Wallet.
Sign in with your Enjin Wallet to keep your progress with the wallet and play on any device. Nucleo NFTs in the wallet give bonuses while you hold them (Profile lists them).
Buy every new element as soon as you can: each one multiplies all energy ×1.25, forever. Push your best element past each 25 atoms (resonance doubles it), tap Excite and catch cosmic rays. In the Lab, start with Binding energy and a faster tick.
Go supernova when it would at least double your stardust. Spend isotopes on permanent upgrades: Stable isotope (×2 energy) first, then Laser, Detector and Half-life. In the Cosmos, build every object at least once: cataloging is a permanent ×1.1.
From 20 elements, trade stardust for neutrons whenever the Kilonova button lights up. Neutrons multiply energy and every future stardust gain, and the first kilonova unlocks Autosynthesis. Build permanent Neighborhood stars: Betelgeuse adds stardust, Cygnus X-1 adds neutrons.
A kilonova worth 10¹⁸ neutrons condenses dark matter for permanent nebulae and galaxies, each revealing the next. The locked Deep Sky tab shows how close you are.
The heaviest elements need astronomically more energy; everything stacks now: collection, stardust, neutrons, cataloged objects, achievements and cosmic age. All 118 is a long road: about 1,000 hours for a dedicated player.
Check in before your offline limit fills up, and chase achievements (+2% each). Autosynthesis only works while the game is open, so an open tab keeps you growing fastest.
