A sci-fi idle game. Spark a thousand-year-dormant Ark back to life, rebuild it system by system, and reset through cosmic eras to grow endlessly stronger — even while you're away.
Idle & Incremental
Automate everything
Prestige & ascend
No pay-to-win · No ads
The Ark has drifted in silence for a thousand years. Its reactor is cold, its corridors dark, its memory fractured into scattered fragments. One faint signal still pulses in the deep — and it's answering you.
Spark the core, restore power, and bring the great vessel back online one system at a time. Every breakthrough recovers a little more of the Ark's history… and hints that its long sleep may not have been an accident.
Read the story
Our biggest update yet adds a guided campaign, an entire late-game civilization to build, and a new surge layer — all free, all save-safe, no reset.
The Map becomes an authored campaign — 214 orders across seven phases that always point to your next meaningful goal, from the very first tap to your first prestige.
The campaign › New
Horizon 4 — spend Continuity Charters earned from prestige to found six permanent settlements and convene the Horizon Council. A civilization that outlasts the Ark.
Horizon 4 › NewThree new charge-up surge bars that stack additively with the Accelerator, plus a Deep Overdrive combo — and now you choose exactly which material your taps gather.
Boosts ›Tap each bar to charge it, exactly like in the game. Push all three past 25% to trigger Deep Overdrive — the bars drain over time, so keep them topped up.
Each bar caps at +400% (×5) and folds additively into the Ark Accelerator — a preview, not the live numbers.
Start with a single tap of the core and grow it into a self-running civilization. Every layer of the machine can be upgraded — and then automated.
Tap the Ark's core, then build reactors, salvage rigs, and fabricators that produce for you around the clock.
Resources ›
Construct and upgrade dozens of ship systems — power, storage, fabrication — each compounding your output.
Buildings & automation ›Unlock automatic tapping and hands-free production so the Ark keeps climbing without you lifting a finger.
Automation ›
Spend across many upgrade tracks — Optimize, Echoes, Memories, the Archive, and the permanent Core Matrix.
Upgrade tracks ›
Deploy specialized crews to distant regions to gather rare materials and push through escalating zones.
Exploration ›
Unlock the Archive's six branches of endless, procedurally-generated research with real, stacking bonuses.
The Archive ›Every collapse and every awakening makes your next run exponentially faster — and peels back another layer of the story.
Build the base economy and bring the Ark back online.
Collapse a run into Time Shards to supercharge the next.
Awaken the Ark for Memory Cores and recover its past.
Endless permanent research that never resets — go further.
Energy
Time Shards
Memory Cores
ARK Cores

Yes — that's the heart of an idle game. Your Ark keeps generating Energy and running its automated systems while the app is closed, so you return to a pile of resources to spend. Come back for a few seconds or a few hours; the Ark keeps climbing either way.
There are two prestige layers. Collapsing a run into a Time Anomaly trades your progress for Time Shards; Awakening the Ark grants Memory Cores and recovers a fragment of its lost story. Both make every future run exponentially faster — and the permanent Core Matrix end-game track never resets at all. See the full progression guide ›
Optional cloud save lets you sign in and carry your Ark between devices, or you can play entirely as a guest on a single device. Your premium purchases are tied to your account and restore after a reinstall.
Yes — the optional Ark Relay Network lets you add friends, share invite codes for bonuses, and compare your progress across the network. It's entirely opt-in; the game is a complete single-player experience without it. Learn about the Relay ›
