A laid-back mine manager where your haul can be swapped for USDT. The exchange isn't always on: over the past year it has been paused for maintenance more than once.
It's a business game about mines. You hire miners, send them into different mines and collect gold coins, then pour the earnings back into the operation: you start with one mine and gradually add more. Miners were also released as NFTs, a collection of more than a hundred, and the developers say some of them, along with future airdrop rewards, can be had for free.
You can swap your haul for USDT right inside the game. You can top up in USDT or TON. Now and then the developers run small prize draws: in one of them first place got 5 USDT and the consolation prize was 0.05.
It hasn't been glitch-free. The USDT exchange was once closed for 48 hours, the game server has gone down for 4-hour maintenance windows, and after one update some players were charged in USDT or TON without receiving their items; that was fixed and affected players were asked to contact support. Maintenance is announced in advance, and compensation arrives in the in-game mail afterwards.
