Clem’s Gems Game Highlights

Clem’s Gems veers off the usual track followed by most slots for real money. Here’s what makes its path underground a little different:

  • Diamond Prizes that don’t wait for paylines: Clem’s Gems scatters Diamond Prizes directly onto the reels, each carrying its own credit value. 
  • Cart Bonuses that build on each other: Most slots offer one bonus at a time, but here, Cart Bonuses can overlap and combine. Extra Spins, symbol upgrades, and boosted rewards can all run together, making bonus rounds exciting.
  • Symbols that get better as you go: During bonus play, regular symbols don’t stay ordinary for long. As features unfold, symbols can upgrade into higher-value Diamonds, while boosted prizes and multipliers raise the ceiling on what a single spin can deliver.

Clem’s Gems Game Features

Clem’s Gems slot game has features that work together while you’re playing.

Clem’s Gems Wild Gems Feature

Wild Gems come in four colors: purple, red, green, and gold. Colored Wild Gems substitute for most symbols and can pay in mixed combinations. Gold Gems can transform into other Wild colors, except when all three bonuses are active during Extra Spins. 

Clem’s Gems Bonus Triggers Feature

Each of the Wild symbols can trigger an associated bonus. These bonuses are:

  • Purple Wild: Can reward you with the Purple Cart Bonus. 
  • Red Wild: Can reward you with the Red Cart Bonus.
  • Green Wild: Can reward you with the Green Cart Bonus.

Multiple carts can trigger on the same spin.

Clem’s Gems Diamond Prize Feature

Diamond Symbols appear on all reels, and each one is assigned a random credit value at the start of every spin. When Diamonds land on both reel 1 and reel 2, those values pay from left to right across adjacent reels, multiplied by your bet, and awarded on top of any regular line wins.

Clem’s Gems Extra Spins Feature

The Extra Spins Feature works as a modifier rather than a traditional bonus round. When active, Bonus Diamond Symbols are added to reel 1 and can turn into +1 or +2 Extra Spin symbols, extending play and allowing other features to stay active longer.

Clem’s Gems Symbol Upgrade Feature

This feature introduces a collection meter that tracks Wild Gems during spins. As collection levels are reached, standard symbols like Pickaxes, Maps, Lanterns, TNT, and Clem himself are upgraded into Diamond Symbols for the rest of the feature, increasing their payout potential.

Clem’s Gems Boosted Prizes Feature

The Boosted Prizes Feature raises the ceiling on Diamond wins by adding high-value Boosted Diamond Symbols to the middle reels and Bonus Diamond Symbols to reel 5. These can award larger credit prizes or apply multipliers to the total Diamond Prize on a spin, all multiplied by the active bet.

Clem’s Gems Slot Bonuses and Jackpots

Clem’s Gems’ reward structure is simple, focusing on fixed prizes rather than separate bonus games. This online casino game offers Mini, Minor, Major, and Grand jackpots that are statically set and scale with your selected bet.

How To Win the Clem’s Gems Slot

In Clem’s Gems, wins come from matching symbols across the game’s fixed paylines, which pay left to right on adjacent reels. Payouts can also land through Diamond Prizes, boosted values, multipliers, and fixed jackpots. Wild symbols can help you unlock winning combinations, as well as bonus payouts from mining carts if luck is on your side.

Clem’s Gems Slot Graphics and Design

Clem’s Gems trades realism for fun and shine, saturating its mining theme in bold colors, glowing gems, and a glossy, arcade-style finish that you can find in other gem-themed slots. The reels pop with high-contrast lighting and animated highlights, making everything easy to follow. As a GAMEIOM slot game, it pairs that visual energy with a fast, banjo-driven soundtrack that keeps the pace upbeat and playful.

Clem’s Gems Slot Symbols

At the top of the lineup in this mining slot is the Diamond Symbol. Instead of having a fixed value, each Diamond shows a credit amount that can also turn into a bonus prize or a fixed jackpot. These rewards are based on your wager and where the Diamond Symbols appear on the reels. 

Among the regular symbols, Clem is the top payer, with five matching symbols awarding up to 200 credits. Just below Clem are mining icons like TNT, lanterns, maps, and pickaxes, which can pay up to 150 for five-of-a-kind. Card symbols from A – 9 make up the lower end of the paytable and top out at 50. 

The game’s bonus symbols are the Wild Gems and special Diamond versions. The Wild Gems pay like standard symbols with up to 200 credits for five, while also helping trigger additional features. The Diamond symbols unlock the slot’s biggest rewards.
