What Is ‘Idle Mine’? This Free iOS and Android Game Pays Real Bitcoin

After finding success with Bitcoin Miner, a vibrant mobile game in which players can earn real Bitcoin rewards for fake-mining an array of cryptocurrencies, Fumb Games has pivoted into a very different kind of mining game.

Idle Mine on iOS and Android is cut from the same cloth as Bitcoin Miner, as both are “idle” experiences that require minimal input, typically in the form of pressing buttons and deciding when and how to spend in-game funds on upgrades. In this case, however, your little miners are digging out gems and serving customers as you expand your operation.

But it also provides real Bitcoin rewards, which you can cash out and spend as you please. Granted, the earnings are tiny—so keep your expectations in check. But if you want to stack up satoshis while playing a simple phone or tablet game, Idle Mine is another option. Here’s how it works.

What is Idle Mine?

Idle Mine is an iOS and Android game that was first released in 2024. This idle game tasks you with running a gem mining operation by spending in-game coins to upgrade particular mines, add staff, and better serve customers.

That’s all done via menus, and when you’re not interacting with menus, the game essentially plays itself: The miners run around, collecting gems and serving customers, and your earnings gradually increase over time.

That’s why it’s considered an “idle” game, because so much of the experience is automated. It’s a lightweight management sim, in other words. There also isn’t much strategy needed, since the game will always put a current “mission” at the top of the screen. Following those is an easy way to keep things simple and focus on gradually earning Bitcoin.

As you play and make upgrades, you’ll earn tiny bits of Bitcoin denominated in satoshis, or 1/100,000,000 of a single BTC. This is real Bitcoin that you can withdraw to a ZBD wallet and then transfer elsewhere or spend as you please.

Idle Mine also has optional in-game purchases to help boost your earnings or speed up mine upgrades. It also has optional video ads that you can watch to get special boosts, such as adding a 5x multiplier to free gifts of coins or “magic gems” used for certain upgrades.

How much can you earn?

As noted above, you should keep your expectations modest. If you play a fair bit of Idle Mine daily, then you might be able to stack up a couple hundred satoshis each day. But at a price of $85,000 per Bitcoin, 200 satoshis is only worth about 17 cents.

We’ve played hours and hours of the game over time, stacking upwards of 4,000 satoshis… but that’s barely a few bucks in total, and we’d rather not think too hard about the per-hour rate.

Basically, it’s a little bit of free crypto as a bonus for playing the game, but don’t expect that Idle Mine or any other play-to-earn Bitcoin game will make you rich.

Funds can be withdrawn into a ZBD wallet, though note that U.S. users in some states may not be able to use ZBD due to local restrictions. Be sure to check before you start racking up hours in pursuit of BTC rewards.

Idle Mine and Bitcoin Miner have both instituted a variable daily withdrawal limit, which is apparently tied to the price of Bitcoin. As of this writing, Idle Mine players can withdraw 330 satoshis per day, or about $0.28 worth.
