Gem Mine

Push-your-luck mining: every safe cell adds coins to a pot you can cash out at any moment — but one Rock Monster takes it all. 3 rounds a day, daily streak bonuses, and a clear bonus for the brave.

Gem Mine is a push-your-luck dig through a 10x10 mine shaft. Every safe cell you reveal adds coins to a growing pot — but 10 Rock Monsters lurk in the dark, and hitting one takes the whole pot with it. Cash out in time and the coins are yours.

Where to find it

How a round works

  1. Click any cell to start digging. Your first click is always safe.
  2. Every revealed cell pays into your pot: plain cells give 2 MPC, common gems 10–20 MPC, and rare gems 25–50 MPC. There are 14 gems in every mine (10 common, 4 rare).
  3. Numbers on revealed cells show how many Rock Monsters sit in the 8 cells around them — classic minesweeper logic. A cell with no number and no neighbours clears its whole surrounding region in one go.
  4. At any point you can press Cash Out to bank the pot and end the round.
  5. Reveal a Rock Monster and the round ends instantly — the entire pot is lost.
  6. Reveal all 90 safe cells and you clear the mine: you bank the pot plus a 250 MPC clear bonus.

The board lives on the server, so you can close the page mid-round and pick the same mine back up later — the Start button becomes Resume Mining while a round is open.

Flags

Suspect a monster? Mark it with a flag: right-click on desktop, long-press on mobile, or switch on Flag Mode. Flagged cells can't be revealed by mistake, and the auto-clear of empty regions politely digs around them.

Plays

  • 3 rounds per day, reset at midnight MPT. VIP members get 2 extra.
  • A play is counted when the round starts — walking away from an open round doesn't refund it (you can always resume instead).

Daily streak

Mining on consecutive days builds a streak worth +5% coins per day, up to +50% at day 10. Every 7th consecutive day is a milestone: that day's first round is free (the play is refunded when it ends). Missing a day resets the streak to 1.

Pet XP

Your active pet digs alongside you and earns XP when the round ends: 25 XP for clearing the mine, 15 XP for cashing out, and 10 XP even when a monster gets you — plus a little happiness either way.

Leaderboard, trophy and charm

  • The daily Top Miners board ranks the biggest banked pots of the day (before coin boosts, so boost items don't decide the podium). Busted rounds bank nothing.
  • The all-time Trophy Case crown is The Golden Geode — most gems found in a single round.
  • Completing 10 rounds earns the Gem Digger charm.
  • The Gem Hunter daily quest counts any round you finish, and banked coins count toward coin-winning quests. Coin-boost items like the Lucky Clover apply when you cash out.

Good habits

  1. The first click is free — open the board somewhere central so the numbers give you the most information.
  2. Greed is the real monster. A guaranteed 150 MPC in the bank beats a 300 MPC pot at 50/50 odds.
  3. Count with the numbers before guessing: a "1" touching a single unrevealed cell has found its monster — flag it and dig everywhere else with confidence.
  4. Late board, big pot, no safe deduction left? Cash out. The clear bonus only pays if you survive every last cell.
