Diamond Mine Extra Gold: a deeper dig into the mine
Diamond Mine Extra Gold is Blueprint Gaming's follow up to its popular mining themed Megaways slot. It keeps the cartoon gold rush setting and the tumbling reels, then adds extra symbols and a reworked free spins round meant to push the win ceiling higher. In our testing it felt like a busier, more generous version of the original rather than a brand new idea, and that is a fair way to set expectations before you play Diamond Mine Extra Gold.
What kind of slot it is
This is a six reel Megaways slot, which means the number of symbols on each reel changes from spin to spin and the count of ways to win moves with it. When matching symbols land they pay, then disappear and let new symbols tumble down into the gaps, so a single paid spin can chain into several wins in a row. The mine theme is light and friendly, with gems, dynamite and a pickaxe doing the heavy lifting. If the Megaways idea is new to you, our guide to slots walks through reels, paylines and features before you stake anything real.
The mechanics
The engine here is the cascade. Every win clears the winning symbols and drops fresh ones in, and that chain continues until a tumble lands with no new win. The "Extra Gold" name points at the change from the first game, which leans on extra high value symbols and a stronger link to the cart and collection idea that the mining theme suggests. The reels can serve up a small win that snowballs through several cascades, and on the right spin the changing Megaways count and a long tumble chain combine into the bigger results. None of this is guaranteed on any given spin, which is the honest way to read a high variance Megaways game.
The bonus features
The headline feature is the free spins round, triggered by landing enough scatter symbols. The draw of Megaways free spins is the progressive multiplier: in many games of this type a win multiplier climbs with every successful cascade and does not reset between spins for the rest of the round, so a hot streak late in the bonus is where the largest results come from. Diamond Mine Extra Gold builds its top end around this kind of escalating bonus rather than the base game. Treat the base spins as the wait and the free spins as the payoff, and do not assume the feature arrives often, because it does not.
RTP and volatility
Blueprint releases its slots to operators in more than one RTP build, so the return on the version you load can differ from one casino to another. Always read the figure on the game's own info screen rather than trusting a number you saw elsewhere, and if percentages are unclear our RTP explainer breaks down what the number means over the long run. Volatility is high. A Megaways slot with a climbing free spins multiplier concentrates its value in the bonus, which means long quiet stretches in the base game between the moments that matter. Our volatility guide explains why a high variance game can drain a balance quickly during the dry spells.
How to play Diamond Mine Extra Gold
The practical approach is the same as any high variance slot. Pick a stake your balance can sustain across many losing spins, because you may sit through a lot of them before the free spins land. Decide a session budget before the first spin and stop when you reach it, whether you are up or down on the day. The cascading wins make the base game feel lively, but that motion is not the same as profit, so do not raise your stake to chase the bonus. Our responsible gambling tools let you set a deposit or loss limit in advance, which is the simplest way to keep the entertainment from turning into a problem.
Is Diamond Mine Extra Gold worth playing?
Strengths: a familiar, likeable theme, the satisfying tumble mechanic, and a free spins round built around an escalating multiplier that gives the game a real top end. Weaknesses: it is more of an upgrade than a reinvention, the variance is high, and the feature is rare enough that many sessions will end without seeing it pay. It suits players who liked the original Diamond Mine and want a slightly punchier version, and it is a poor fit for anyone who prefers steady, low swing play. It is entertainment and never an income plan. For more from the studio read our Blueprint Gaming review, and choose a licensed site from our casino reviews. 18+.
