Idle Grind

What is Idle Grind?

Idle Grind is an idle mining game on Robinhood Chain mainnet. A rack of virtual rigs mines an in-game resource called GRIT around the clock, including while you are offline. GRIT buys better hardware and can be refined into $GRIND, an ERC-20 token on Robinhood Chain that you can claim to your wallet or spend on power-ups. Entry works by holding: the game checks your wallet balance every session and locks the rig room below 250,000 $GRIND. The project's pages give no price for that amount, so the real cost to start is whatever 250,000 $GRIND costs on the day you buy.

Rigs, tiers and refining

Six shop tiers run from the Dusty Laptop to the Quantum Node, each purchase raises the next price by 15 per cent, and three matching rigs can be fused in the Forge to jump a tier. Your holding sets your holder tier, from Visitor at 250K $GRIND (0.25x mining speed, 25,000 $GRIND daily withdrawal limit) to Overlord at 40M (3x, 1.25M). The docs give a base refining rate of 80,000 GRIT per $GRIND that rises by 8,000 GRIT every Sunday at 6:05 PM Pacific; the homepage showed 80.0K on 5 November 2026, so check the Refinery for the live figure.

Claims, fees and seasons

Claiming refined $GRIND carries a 10 per cent tax (5 per cent burned, 5 per cent to the treasury) plus a 0.0002 ETH network fee, a 24-hour cooldown, a 25,000 minimum and your tier's daily limit. Withdrawals unlock only after you have held 250K continuously for 48 hours. Each week is a season that ends on Sunday at 6 PM Pacific: the top 12 miners by GRIT split a $GRIND pool, with first place taking 20 per cent. The pool size is announced in Discord each week and scales with game revenue, and winners must still hold 1,000,000 $GRIND at reset. On 5 November 2026 the homepage showed Season 6 with the reward still marked as announced soon.

How it is built, and the risks

The docs say $GRIND was minted once at launch and that new tokens reach players only through refining from the reward treasury. The game runs without a custom smart contract: the hold check is a read-only balance query, while unclaimed GRIT and pending $GRIND live on the game server until you claim them. The docs tell players to treat pending balances as game progress, not custody. If the treasury balance falls below set thresholds the daily cash-out cap is halved, and the docs call $GRIND a utility token that may lose all value.
