An honest crypto-mining idle game: buy rigs, grow your hashrate, and watch block rewards halve over time. No real cryptocurrency involved — just the economics, gamified in your browser.

How to play

  1. Click Mine to earn your first coins, then buy your first rig.
  2. Rigs add hashrate, which finds blocks automatically over time.
  3. Rig prices scale up as you buy more — plan your upgrades.
  4. Watch the reward halve every 10 blocks, just like real halvings.

Build a virtual mining operation: buy rigs, stack hashrate, and earn simulated block rewards that halve as more blocks are found — the same scarcity mechanic real proof-of-work coins use. To be clear: no real cryptocurrency is mined, earned or spent here; it is an idle game that happens to teach you why home mining gets harder over time.

Frequently asked questions

Does this mine real cryptocurrency?
No. Nothing real is mined, earned, or spent — it is a simulation game. Real browser mining of Bitcoin is effectively hopeless, which is part of what the halving mechanic here illustrates.
Why do rewards keep shrinking?
The game halves the block reward every 10 blocks, mimicking real proof-of-work halvings — the mechanism that makes coins scarcer and mining progressively less rewarding over time.
Is my progress saved?
Progress lives in the page while it is open. Refreshing starts a fresh run — treat each session as a new speedrun.
