How a round works

Mine Island from SmartSoft Gaming, the Georgian studio behind JetX, takes the Mines formula to a tropical island. Instead of tiles, you dig in the sand; instead of stars, you find treasure.

  1. Set your stake.
  2. Dig a spot. If it’s safe, you find treasure, your multiplier rises and you move up a level.
  3. Collect at any time to bank stake times the current multiplier.
  4. Hit a mine and the round ends; the bet is lost.

The level system gives the game a sense of progress: each level is a new stage of the island, with its own multiplier.

Features

  • Level up: each safe dig moves you to the next level with a higher multiplier.
  • Collect at any time: there’s no penalty for stopping early.
  • Multipliers: each level’s payout is shown before you dig, so you always know the reward and the risk.

The top multiplier is 100x the stake.

RTP and the odds in plain words

SmartSoft publishes an RTP of 98%. In step games like this, each level’s multiplier is set from your chance of surviving that far, which keeps the long-run return the same whether you stop at level one or level ten.

Here’s the idea in numbers. If each dig had a 75% chance of being safe, surviving two digs would happen about 56% of the time, four digs 32%, and eight digs 10%. The multipliers rise to match. Playing further is not “better” or “worse” value; it’s a bigger, rarer prize.

Is Mine Island provably fair?

Our data doesn’t confirm a provably fair verifier for Mine Island. SmartSoft says its games run on a certified RNG tested by labs. That means you trust the testing and the casino’s licence rather than checking each round yourself. For a Mines game you can verify, try Spribe’s Mines, explained on our provably fair hub.

Honest tips

  • Decide your collect level before you start. Step games are designed to make “one more” feel safe.
  • Each dig is independent. Surviving three digs doesn’t make the fourth safer or riskier.
  • Use the demo to get a feel for how far you’re comfortable going.
  • Beware of predictors. Mine positions are random; anyone selling hints is running a scam.

Where to play Mine Island for real

SmartSoft games are carried by offshore casinos with crash and instant sections. Our featured casino is 1Win (500% up to R75,000 over 4 deposits); search for Mine Island in the fast-games tab. Check whether bonus wagering counts on instant games, as many offers exclude them.

Other mining games: Falling Pickaxe from Pixmove and Mary's Mining Mania from Evoplay. More step games, including Chicken Road, are on the instant win hub. Help is available on 0800 006 008.
