Is Infinite Miner free to play?
Yes, completely. Infinite Miner is free to play in any modern web browser. There is no download required, no app to install, and no upfront cost of any kind. Visit InfiniteMiner.com and start playing immediately. An optional free account lets you sync your save across devices.
Does my progress save automatically?
Yes. The game autosaves your progress at regular intervals during play. Your ore, credits, planet position, miners, upgrades, and run state are all preserved. If you play without an account, your save is stored locally in your browser. Creating a free account backs your progress up to the cloud, which means you can continue from any device and your save will not be lost if you clear your browser data.
Does Infinite Miner work on mobile?
Yes. The game is designed to play well on mobile browsers. The interface adjusts for smaller screens, and touch input is fully supported. Drilling, selling ore, deploying miners, purchasing upgrades, and navigating between panels all work with tap controls. For the best experience on mobile, use a recent version of Safari or Chrome.
How many planets are there?
Infinite Miner is genuinely endless. Planets are generated procedurally from a unique run seed, and the generator continues indefinitely. There is no authored final planet. The deeper you travel into the galaxy, the harder and more economically rewarding the planets become. Players who have completed dozens of Star Drive resets continue to discover new challenges and increasingly valuable worlds.
How do auto-miners work?
Auto-miners are purchased units that produce ore and drilling depth automatically on a timer. You deploy them from the sidebar using credits. Each miner type has its own cost, cycle rate, and production values. When a miner completes a cycle, it pays out ore and depth directly to your current totals without requiring any input from you.
Miner output is boosted by run upgrades purchased during transit windows and by permanent Star Lab bonuses. This means the same miner becomes more efficient the more you have invested in the supporting systems. Early-game miners that feel modest in your first run can become very significant contributors in later runs.
What are upgrade credits and how do I use them?
Upgrade credits are a secondary currency earned from completing planets. They are required alongside standard credits to purchase run upgrades during transit between planets. Unlike credits, you cannot grind for more upgrade credits mid-planet: each planet grants a fixed amount, and later planets grant fewer than earlier ones.
Because upgrade credits are scarce, you cannot buy every available upgrade in a run. You have to decide which upgrade categories matter most for your current strategy and commit to them. This scarcity is intentional: it creates meaningful run-to-run decision making rather than simple accumulation.
What are contracts?
Contracts are optional per-planet challenges that are generated at the start of each run. Each contract attaches to a specific planet and imposes a constraint on how you play within it. Examples include selling ore below a credit threshold, completing the planet without purchasing miners, avoiding a specific upgrade category, or finishing within a limited number of sell actions.
Satisfying a contract rewards you with bonus resources that are useful for the run. Contracts are not required to complete a planet or progress to the next one, but the rewards are significant enough that experienced players generally try to satisfy them whenever possible, even if it means adjusting their usual approach.
What is Star Drive?
Star Drive is the prestige system in Infinite Miner. When you activate it, your current run resets: credits, ore, temporary run upgrades, and planet progress are all cleared. In return, you earn Star Shards based on how far you travelled and how much wealth you accumulated before resetting.
Star Shards are spent on permanent upgrades in the Star Lab. These upgrades carry forward into every future run and make your ship meaningfully more capable from the very first planet. Upgrades in the Star Lab affect things like starting capital, mining efficiency, miner output scaling, and economy bonuses across the board. A ship with several Star Lab upgrades active starts each run substantially stronger than a fresh ship on its first attempt.
When should I use Star Drive?
The right moment to activate Star Drive is a judgment call that gets easier with experience. As a general guideline, if your progress through planets has slowed significantly and you feel like upgrading further would take a very long time, that is usually a good indication that your run has reached its natural limit.
Resetting early loses some Star Shards you could have earned by pushing further. Resetting very late means spending a lot of time on diminishing returns when a fresh run would move faster. Most players develop intuition for the reset timing after a few runs, and the permanent upgrades they unlock make each subsequent run noticeably quicker from the start.
Can I lose my progress permanently?
Standard gameplay does not cause permanent progression loss. Star Drive resets your current run but all Star Lab upgrades and Star Shards from previous runs are preserved. Your permanent progression only grows, never decreases.
If you play without a registered account, your save lives in your browser's local storage. Clearing browser data or switching browsers would lose that save. Creating a free account protects your progress with cloud saving and lets you continue on any device.
What is a run seed?
Each run in Infinite Miner is generated from a unique seed value stored with your save. The seed determines the entire sequence of planets for that run: their names, mineral compositions, layer structure, ore value, terrain type, and unlock costs. Planets are generated deterministically from the seed, which means the same run always regenerates the same planets if you reload the game.
When you perform a Star Drive reset, a new seed is created, and the entire galaxy regenerates from scratch. Your new run will contain a completely different set of planets from your previous one.
