Femur Idle: what it is, rules and how to leave it running on your PC

What is Femur Idle

Browser idle MMORPG with four classic vocations, where the character hunts on its own in the chosen zone and the player controls how many monsters to pull at a time. The economy mixes in-game gold with real money: a shop and Bazaar in USDC on the Solana network and 'contributions' via PIX that become a tradable currency. The hunt stops when the tab is closed, and the game is for adults 18+ only.

• Four vocations: Knight, Paladin, Sorcerer and Druid; you can have several characters on the same account.
• The hunt runs on its own but stops when the player disconnects; what has been earned stays saved and the hunt restarts when you return.
• Hunting session of up to 4 h on a free account and 12 h on Premium, according to the values shown in the documentation.
• Premium is time-based and applies to the whole account: +20% XP, more critical chance and damage, a depot of 1,000 items (300 on free) and advanced imbuements; keeping a house requires active Premium.
• The documentation lists 122 hunting zones (77 marked as Premium) and a maximum level of 2,000.
• Shop purchases are charged in USDC on the Solana network and approved in the player's wallet.
• The Bazaar sells characters, outfits and mounts for Femur Coin or USDC; in USDC sales the payment goes wallet to wallet and 15% goes to the marketplace fee wallet.
• PIX contributions credit the premium currency (TC/Femur Coin), which the terms say can be sent to other players and exchanged for USDC on the Market.
• In-game gold is separate from the token and cannot be withdrawn.
• Adults 18+ only; operated by Rafael Renti da Fonseca (CNPJ 68.385.598/0001-18).

Do you need to keep the tab open?

Femur Idle only advances while the page is open.

The hunt stops when the player disconnects or closes the tab; what has been earned stays saved and the hunt restarts when you return. Imbuement timers are paused offline. A hunting session lasts up to 4 h on a free account and 12 h on Premium. The hunt stops, and everything you had already earned is kept. (source)

That's where a regular browser gets in the way: Chrome and Edge save resources on tabs you're not looking at — they hold back timers, stop animations and, over time, may discard the tab. A discarded tab or a connection that dropped overnight means progress stopped until you come back. The details and browser settings are in the guide why idle games stop in the background.

Rules: multiple accounts, automation and VPN

What the rules published by Femur Idle said on Sep 22, 2026:

• Multiple accounts: allowed. The rules allow more than one account and more than one character, but using one account to feed another (referrals, trades and party loot between accounts of the same person) is treated as fraud. The privacy policy mentions IP and device signals to detect multi-accounting. You may hold more than one account. (source)
• Automation (bots, macros, scripts): forbidden. Only the automation the game itself offers is allowed; programs that play for the player are prohibited, and the rules treat automating what is not idle as cheating. scripting the parts that are not idle is cheating. (source)
• VPN and proxy: the site doesn't say. Rules, terms and documentation do not mention VPN or proxy.
• Selling items for real money (RMT): allowed. Buying and selling with money is part of the game, through the official channels: in the Bazaar, characters, outfits and mounts go for Femur Coin or USDC (wallet-to-wallet payment, 15% fee), and the terms say the transferable premium currency can be exchanged for USDC on the Market. Selling accounts, characters, gold or items outside the official Market is prohibited. Players who grind sell to players who would rather buy. (source)

The full rules are at femuridle.com/rules. Game rules change: read the current version before you start.

Real money comes with risk: there are no guaranteed earnings, the price depends on who's buying and deals closed outside the game's official system have no guarantee at all. The guide crypto idle games: how they work and the risks explains it calmly.

How to leave Femur Idle running in IdleDeck

1. Download IdleDeck (free, Windows 10 and 11) and link the app to your IdleDeck account — it takes a minute.
2. Click Add account, go to Other game or site and paste femuridle.com/play.
3. Sign in to your Femur Idle account in that window, just like in the browser. Each IdleDeck account has its own login, cookies and cache — repeat step 2 for each account the game's rules allow.
4. Turn on alerts: Windows notification, sound or a Discord webhook to know on your phone when the account drops.
5. You can minimize. The page stays awake with the window minimized or in the tray. If it drops, IdleDeck retries on its own; if the game's connection drops, it alerts you — and reloads on its own if you turn that option on in the settings.
