Diamond Mine: a mining Megaways slot with a rising multiplier
Diamond Mine is Blueprint Gaming's mining-themed Megaways slot, one of the early titles to pair tumbling reels with an uncapped multiplier in the free spins. It is a high-variance game that lives and dies by its feature. Here is how Diamond Mine works and where its bigger wins are concentrated.
A Megaways grid down the mine
Diamond Mine uses the standard Megaways setup of six reels that each show a varying number of symbols every spin, so the number of winning ways shifts spin to spin and can climb into the hundreds of thousands. Wins clear in a tumble, with fresh symbols dropping into the gaps for the chance of a chain on a single stake. The theme is gems and miners, with picks, carts and diamonds as symbols, but underneath it is the familiar Megaways engine. If that format is new to you, our slots guide walks through it before you put money down.
The free spins and the unlimited multiplier
The reason to play Diamond Mine is the free spins round. Trigger it with scatters and an unlimited win multiplier begins climbing with every tumble and does not reset for the rest of the feature. That rising multiplier is the engine behind the slot's potential: a long sequence of tumbles late in the round, when the multiplier is high, is where the largest wins land. The upside is a feature with a genuinely high ceiling. The catch is the variance. The base game can run cold, the round is not easy to trigger, and a free spins session that ends quickly with a low multiplier can pay very little. The big rounds are the exception, not the rule.
RTP and volatility
Blueprint supplies operators with more than one RTP build, so the figure on the info screen is the one that applies to your session rather than any single number quoted elsewhere. Check it first and read our RTP guide if it is unclear. Volatility is high, which is exactly what an uncapped multiplier feature implies. Our volatility guide explains the trade you are making: a large top end in return for long dry runs and rare big hits.
How to play Diamond Mine
Patience and a careful bankroll matter here. Keep the stake small so your balance can survive the cold stretches and still reach a feature, and decide up front how much you will spend chasing one. Set a loss limit before the first spin rather than after a bad run. Our responsible gambling tools make it easy to cap a session in advance. The high variance also makes Diamond Mine a poor choice for clearing bonus wagering.
Is Diamond Mine worth playing?
Strengths: a solid Megaways engine and a free spins round with an uncapped multiplier and a real top end. Weaknesses: a thin base game, a feature that is hard to reach, and harsh variance, so without a strong round there is little to enjoy. It suits players who like high-risk Megaways slots and can wait for the rare big result. Anyone who wants steady, frequent action should look elsewhere. It is entertainment, never an income plan.

Diamond Mine FAQ
Does Diamond Mine have an unlimited multiplier?
Yes. In the free spins round the win multiplier rises with every tumble and does not reset for the rest of the feature, so a long chain of tumbles when the multiplier is high produces the biggest wins.
What is the volatility of Diamond Mine?
It is high volatility. The base game can run cold and the feature is hard to trigger, so expect long dry runs and rare large payouts rather than steady wins.
Where can I play Diamond Mine?
It is available at many licensed casinos that stock Blueprint Gaming. Pick a regulated site from our casino reviews, confirm the RTP on the info screen, and set a budget before you start. 18+.
