Rock Vegas (Pragmatic Play) – Review & Demo Play

Overview of Rock Vegas Slot

Rock Vegas takes the stone age theme and ties it to a two-part experience. The base game runs on a 5x3 setup with 20 paylines, while the real action sits in a Mega Hold & Spin bonus on a 10x10 grid. Stakes start at 0.20 and reach 240 per spin. No wilds appear at any time, so premium line hits carry the base. I found the base fairly barebones, but the feature can snowball fast once rocks and multipliers start stacking.

Rock Vegas Slot Review and Gameplay

The 5x3 game pays left to right with a friendly caveman on the left and beasts on the reels. It keeps things simple: nine regular pays, no wilds, and scatters as the only route to features. I rate the base game as a dead-spin and top-up-win grind, though premium five-of-a-kind hits can still land tidy returns. The look is slightly dated, yet it fits the prehistoric jungle vibe well enough.

This slot lives on its second reel set. Triggering the Mega Hold & Spin flips the board to a 10x10 grid where only coloured rock symbols or blanks appear. You start with three respins and every rock that lands sticks, resetting the counter to three. Clusters merge into larger rocks with attached prizes, and key symbols feed a trail that opens Mystery Chests. I’ve had stretches where that loop feels tense and rewarding in equal measure.

Rock Vegas Betting, RTP, and Win Potential

RTP is listed at 96.64% by default, though it is a variable setup, so operators may run lower profiles. Volatility is high, scored 5 out of 5, which matches how the base behaves. The headline figure is a 10,000x max win, gated behind the Mega Hold & Spin and its multipliers. The bet range of 0.20 to 240 covers both casual spins and higher stakes. I treat it as a bonus-driven slot with swingy balance curves.

Rock Vegas Symbols and Their Payouts

Low pays are 10 to A. A five-symbol line ranges from 3.75x to 6.25x. Premiums feature a caveman, a sabre-toothed tiger, a dinosaur, and a mammoth. Five of a kind pays 12.5x to 37.5x, with the caveman on top. The caveman also pays from two of a kind at 0.75x. There is no wild symbol in this game, so building lines and chasing scatters matters more than in many slots with substitute mechanics.

In the feature, base symbols vanish and you only see coloured rocks. Values are tied to colour: blue 0.1x, green 0.2x, yellow 0.4x, pink 0.6x, and red or gold 1x the bet. Land clusters to merge them into bigger rocks with stronger prizes. It’s a clean split between payline maths in the base and cash-on-reels values during the Mega Hold & Spin, and that contrast defines the flow from spin to spin.

Rock Vegas Bonuses and Special Features

Three or more scatters trigger the Mega Hold & Spin. The grid expands to 10x10, and only rocks or blanks can land. You begin with three respins. Any new rock that lands sticks and resets the counter to three. If you trigger with four scatters, blue rocks are removed. Trigger with five, and blue and green are removed, lifting the average value. Fill the grid or run out of respins to end the round.

Matching rocks that form 2x2 or 3x3 clusters merge into larger symbols. These carry a random prize: 2x2 formations award between 5x and 10x, while 3x3 formations award between 35x and 500x. Some rocks land with key icons. Keys climb a trail beside the grid, opening Mystery Chests at set points. Chests can add an instant cash prize up to 500x, apply a random multiplier to a rock, add 4 to 10 keys, grant a retrigger, or add a general multiplier for the end.

Reach the end of the trail to reveal a Mystery Multiplier of x2 to x100, which is applied to the total win from the feature. If you fill the grid, the Hold & Spin retriggers on a cleared board. I’ve had runs where keys stack in quick bursts, chests line up, and the total win multiplier climbs. The feature stands out thanks to the large grid, the merge mechanic, and that key-collect loop that can swing results sharply.
