Gem Rush (Slotmill) – Review & Demo Play

Gem Rush Slot Overview

Gem Rush drops me into a gem mine with a 5x7 grid and a quirky Gem Crusher perched beside it. Each base spin starts with stone blockers cluttering up to fifteen positions, trimming the ways until I blow them out of the way. The set-up leans on avalanche wins, so every hit clears and tumbles symbols for new chances. The scene looks other-worldly, with warm rock shades and a pink sky, yet the mechanics stay front and centre throughout.

I pick stakes from 20p to £50 and chase wins on three or more consecutive reels from the left. With blockers gone, the panel opens to 16,807 ways, which pairs well with a progressive win multiplier that resets between base spins. The volatility is high, and the RTP comes in at 96.1%, which sits right where I like it for long avalanche chains. Wild gold nuggets help build lines, while scatters sit ready to kick off the bonus.

Gem Rush Slot Information

The paytable keeps things clear. J to A are the low pays at 0.4x for five of a kind. Pickaxe, bucket, helmet, and torch form the mid tier and return 0.6x for five. The top line is the blue, green, red, and purple gems, paying between 1x and 2x for a five-symbol way. Wilds are gold nuggets that substitute for everything except the scatter, which appears as a gem cart and is the key to free spins.

The grid starts with up to fifteen stone blocks that do not pay and only get in the way, yet dynamite from the Gem Crusher can clear them and raise the ways. Opening the field to its full size gives 16,807 ways across five reels and seven rows. The game caps out at 10,000x the bet, with stakes from 20p to £50. I’ve found the maths pairs steady base play with bursts when the multiplier climbs through chained avalanches.

Gem Rush Slot Features

Every win triggers an avalanche and feeds a block into the Gem Crusher to the right of the reels. That block might be empty or carry a Power-Up. I’ve seen Multiplier Increases of +1 to +5, Wild Conversion on a chosen symbol, Gem Conversion to turn a symbol into gems, Random Wilds adding three to seven, Column Wilds filling a reel, and Dynamite removing five blockers to open fresh ways. Extra Spin appears only during the bonus.

Land three, four, or five scatters anywhere to trigger five, seven, or ten free spins. Free spins play on the full grid with no blockers, so all 16,807 ways are active from the first spin. The progressive win multiplier and the Gem Crusher progression do not reset during the round, which is where the slot comes alive. Scatters do not show up in free spins, yet the Extra Spin block from the Crusher can tack on more.

If I fancy cutting the wait, Fast Track offers four buys. Expand costs 10x for a spin without blockers, Expand+ costs 40x and starts at x3, Bonus costs 100x for free spins, and Bonus+ costs 400x with a starting x10. The published RTPs are 96.35%, 96.46%, 96.59%, and 96.8% respectively. Where available, Burst Mode lets me set a stake and number of spins and rip through results quickly, pausing if a bonus lands.

Gem Rush Slot Conclusion

Slotmill has kept the theatrics light and the gameplay sharp, which suits me. The Gem Crusher feeds the grid with timely twists, and the dynamite is brilliant at clearing the clutter so avalanches can flow. Free spins on the full set-up feel like the sweet spot, especially with a multiplier that holds between spins. Bonus+ is pricey yet tempting for an x10 head start. With high volatility and a 10,000x ceiling, Gem Rush gives me enough bite to keep coming back.
