Mines Supreme Review (2026): A Polished Mines Game — But Check Your Casino's RTP First

The Mines Supreme slot isn't really a slot at all. It's Hacksaw Gaming's upgraded take on the classic Mines formula — part of their Dare2Win series — where instead of reels and paylines you're clicking squares on a grid, banking Diamonds, and trying to cash out before you hit a bomb. Released on June 30, 2026, it wraps that simple, addictive risk-management loop in Hacksaw's usual high-gloss presentation and dangles a 10,000x max win in front of you.

But before you get anywhere near the gameplay, here's the thing you absolutely need to know, and the reason this review exists: Mines Supreme runs on five different RTP settings, and your casino decides which one you get. That single fact matters more than any feature on the grid. Play the Mines Supreme demo to learn the mechanics for free — but read the RTP section below before you wager a cent anywhere.

The RTP Problem: Why You Must Check Before You Play

Let's deal with the elephant on the grid first, because it's the whole story. Most modern instant-win games run a fixed RTP around 96%. Mines Supreme doesn't. Hacksaw's own product sheet lists it in five configurations, and the gap between the best and worst is enormous: the top version returns a generous 98%, while the bottom version returns just 86%. On an 86% setting, you're handing the house nearly triple the edge you'd face on the 98% build — same game, same clicks, same Diamonds, wildly different value.

The catch is that the casino picks the version, and most won't advertise which one they've loaded. That's not a hypothetical: in our own checks, we found Fezbet Casino running Mines Supreme on a noticeably lower RTP than other casinos we compared. So this is our standing advice on the Mines Supreme slot, and honestly on every Hacksaw title: open the in-game info panel and read the RTP before you play. If it says 94% or below, walk to a casino running the 96–98% version. The gameplay is identical; only your long-term value changes, and it changes a lot.

How Mines Supreme Plays

The core loop is beautifully simple, which is the appeal. You set your grid size (3×3 up to 9×9), choose how many Mines to bury, and start clicking squares. Behind each one is a Diamond, a Mine, a Shield, a Multiplier, or the jackpot-tier Max Win Diamond. Every Diamond you uncover adds to your running collectable win. Hit a Mine and you lose the lot. The entire tension is the same one that made Mines a phenomenon: do you bank what you've got, or click one more square?

Because you set the grid and the mine count, volatility is genuinely in your hands — a big grid with one Mine is a low-risk grind, while a small grid stuffed with Mines is a coin-flip for big multipliers. That's why the sheet lists volatility as "variable." There are no reels, no free spins, and — unusually for Hacksaw — no bonus buys. Everything is on the table from the first click.

Slot Features: Shields, Multipliers and the Max Win Diamond

Three symbols lift Mines Supreme above a bare-bones Mines clone:

• Shields: A Shield is a one-time defuse — it neutralises the next Mine you reveal, effectively an extra life. While a Shield is active the COLLECT button locks until the Mine is defused, after which you can bank or push on. It's the game's cleverest wrinkle and adds real decision-making.

• Multipliers: Uncover one and your current collectable win is boosted by 2x, 3x, 5x, 10x, or 100x. Crucially, once applied, every new Diamond then adds to that boosted total — so an early 100x can snowball a round fast.

• Max Win Diamond: The jackpot symbol. Reveal it and you're instantly paid the full 10,000x max win and the round ends. It's the rare, run-ending dream ticket.

Add unusually deep Autoplay — both Random and Custom pick-patterns, plus turbo mode — and Hacksaw has clearly built this for players who like to automate their risk. It's a polished, feature-complete take on the format.

Final Call: Great Game, One Big Catch — 6.40/10

Mines Supreme is a slick, well-built, endlessly replayable version of a proven formula, and the Shield and Multiplier symbols give it just enough depth to stand slightly above the flood of Mines clones — which is why it scores a strong 7.20/10 on innovation and 7.00/10 on potential. The 10,000x ceiling and the flexible €0.10–€10,000 stake range give it broad appeal for both cautious grinders and high-rollers. But two things hold it back. The market is already saturated with near-identical Mines games, and — far more importantly — there's that RTP lottery. On a 96–98% setting this is a fair, fun game well worth your time. On an 86% setting it's one to avoid outright. The game itself doesn't decide which you get; your casino does. So enjoy the Mines Supreme demo, and if you play for real, make the RTP check non-negotiable — it's the single biggest factor in whether this game is good value or a bad deal.
