GramMiners is a 3D mining game on the TON blockchain (mainnet). Play it as a Telegram Mini App or in the browser.

How it uses TON: you sign in with a TON wallet through TON Connect (Telegram Wallet, Tonkeeper and others). Signing in is a signature, not a transfer. Your balance is in GRAM, the native coin of the TON network (formerly Toncoin). Top up with GRAM or with USDT on TON, which is exchanged into GRAM. Withdrawals go in GRAM to the TON wallet you signed in with.

Each strike costs from 0.01 to 0.10 GRAM, and its result is random: you can win or lose your stake. Close seams, find four minerals, sell them, trade them on the player market or craft picks.

New players get 30 free strikes. Their winnings collect in a gift piggy bank, up to 0.50 GRAM. To claim it, top up at least 3 GRAM and make another 3 GRAM of strikes within 72 hours.

18+ only.
