Gemine: Slot Overview

You likely don’t need reminding, but online slots tend to recycle the same themes, symbols, and ideas time and again. One of the most familiar sights is the glittering gemstone, used for all sorts of reasons. Gems are typically associated with value—both in terms of money and visual appeal—so it’s no surprise they’ve appeared in countless slots, and that trend doesn’t look like it’s slowing down. Here’s another entry, this time from developer Pragmatic Play. It’s called Gemine and, in a very typical slot-world twist, it’s essentially a reskin of Pragmatic Play’s other gem-packed title, Gems Bonanza.

Gems Bonanza leaned into an Aztec-style vibe, as though players were adventurers or explorers chasing down local treasures. Gemine is less specific in its setting, placing the action far underground in a cave lit up by the sheer number of gems scattered around. The same slightly mystical collection meter returns on the side of the screen, and this time you’re accompanied by a bearded miner character who shows up on wild symbols. Gemine is more plain and general than the game it borrows from, but it does what it sets out to do.

Gemine is a cluster pays grid slot that uses a board of 8 columns by 8 symbols. With each spin—where players can stake 20 c to $/€100—a total of 64 symbols fall into place, and the aim is to land clusters of at least 5 matching symbols. To count as a cluster, matching symbols must connect horizontally or vertically. Gemine is a highly volatile title, offering a theoretical return of 96.55%, or 96.51% if the bonus buy option is used.

The tumble mechanic removes all symbols involved in a winning cluster from the grid. Any gaps are then filled as symbols drop down from above, with fresh symbols appearing at the top wherever required. If the tumble creates another win, the tumble triggers again, continuing until no further wins appear. The seven standard paying symbols are all gemstones. A cluster of 5 matching gems returns 0.1 to 1 times the bet, while the top end of the pay scale is a 25+ cluster, worth 50 to 1,000 times the bet. The miner wild supports this by substituting for any regular paying symbol, and it can contribute to multiple wins at once. That said, the wild only shows up through the Wild Miner or Lucky Miner feature.

Gemine: Slot Features

One notable change between Gemine and Gems Bonanza is that Gemine includes a bonus buy. Aside from that, it’s largely familiar territory—spin features plus the Gems Feature.

Spin Features

In the base game, each spin can display 5 special-coloured markings, one of each type, behind symbols in random positions. If a win lands on a marked position, it activates the relevant special modifier based on the colour of that mark. Any triggered feature(s) play out after all tumbles from the current spin have finished:

• Blue mark awards Mining – the grid is wiped of symbols, forcing a fresh drop.
• Purple mark awards Wild Miner – every instance of one randomly chosen symbol type turns into wilds.
• Yellow mark awards Squares – random 2×2 blocks of the same symbol type are placed into random reel positions.
• Red mark wards Super Gems – a random 3×3, 4×4, or 5×5 block of the same symbol type is added in random spots on the grid.
• Green mark awards Lucky Miner – 5 to 15 wild symbols are inserted onto the reels in random positions.

When more than one feature is triggered on the same spin, they resolve in this order – Mining, Wild Miner, Squares, Super Gems, and Lucky Miner.

Gems Feature

With every spin, the number of exploded winning symbols is added to the Gems Feature meter. Reaching 114 points from a base game spin activates the Gems feature. The meter resets to zero once no additional winning symbols explode during a tumble sequence. The feature starts after all tumbles and modifiers have completed, starting at level 1. While the feature is active, each level guarantees that all spin modifiers are guaranteed to be played once per level, in order, and all wins receive an x2 multiplier. Gathering enough winning symbols within a level moves players to the next level:

• Level 2 – collect 116 winning symbols. Level 2 has an x4 multiplier.
• Level 3 – collect 120 winning symbols. Level 3 has an x6 multiplier.
• Level 4 – collect 124 winning symbols. Level 4 has an x8 multiplier.
• Level 5 – collect 132 winning symbols. Level 5 has an x10 multiplier.

The feature finishes if you fail to collect enough symbols to reach the next level, or once all features from level 5 have been completed.

Buy Gems Feature

Players can purchase the Gems feature for 100 times their bet. A bought feature plays out identically to one triggered naturally.

Gemine: Slot Verdict

When Gems Bonanza first launched, it felt like Pragmatic Play taking a run at Play’n GO on its own turf. It echoed, to an extent, the kind of Play’n GO slots built around collecting winning symbols until certain thresholds unlock features. A well-known example is the big-eyed, alien-filled success Reactoonz—the first of multiple ‘toonz’ sequels. Now, three years later, the “collect symbols to trigger modifiers” approach is so common that it no longer feels like a direct Play’n GO comparison. The structure has spread well beyond where it started. What hasn’t shifted in that time, though, is how Gemine plays.

That’s understandable, since it’s difficult to reinvent something when a studio chooses to largely duplicate an earlier release. The main gameplay difference between Gemine and Gems Bonanza is the bonus buy option. It doesn’t meaningfully change how the bonus portion functions, but it does let players skip straight to level 1, with all the usual advantages and drawbacks that come with buying bonus rounds. One key point is the reduced maximum win, which is now limited to 7,500x rather than 10,000x.

So it goes—another day, another reworked slot. In truth, this is more of a redo or re-release than a true revamp. Pragmatic Play clearly doesn’t mind revisiting and remaking games from its large and fast-growing catalogue; after all, the core of Gems of Bonanza had already been recycled previously in Santa’s Wonderland. As for Gemine, it’s a fairly average example. It swaps in a mining setting instead of a Central/South American theme and adds a bonus buy, but beyond that, it doesn’t offer much new.
