Rock Vegas slot Big Win January 2022

On the next day after its wide release, on January 25, the new Rock Vegas slot from Reel Kingdom paid a massive 6,692x prize to a British gambler. All that happened in the flashy bonus game, which dragged for over 6 minutes.


With a bet of £1, the player landed 3 bonus symbols and activated the Mega Hold and Spin feature.


The grid started to fill rapidly, so it didn't take long for the player to fill the trail and unlock a 6x mystery multiplier.


As the grid filled entirely, he proceeded to the next one. By that time, the total cash prize was £85.20.


The second grid filled pretty fast as well, and the total win was increased to £135.40.


Once a key dropped and unlocked the chest, it awarded 7 more keys that led to another mystery multiplier, which became 12x.


The player didn't manage to fill the third grid, though, he didn't leave disappointed for sure, as the feature ended up paying a total prize of £6,692.40.

Rock Vegas Review

Evidence of gambling activity has been dated all the way back to the prehistoric Paleolithic period, also known as the Old Stone Age, so the premise of Reel Kingdom’s Rock Vegas Mega Hold & Spin isn’t too far fetched. We doubt they had big, flashy stone age casinos though, but playing around with sticks, bones and rocks was probably not unheard of. Rocks play a central part in this Pragmatic Play powered release as well, but only in the bonus round.

The base game is a barebones experience with zero extras, not even wilds, so 750x your stake is the most you can hope for if you’re lucky enough to fill the screen with the top-tier caveman. The Mega Hold & Spin feature plays out on an unusually large 10x10 grid, and it comes with multi-colored cash stones that merge to award larger prizes. Overlay keys are collected to move you along the mystery modifier trail, and this is how you close in on the 10,000x potential.

Rock Vegas Slot Features

You win between 12.5 and 37.5 x your stake when you land 5 premium symbols on a payline, and the caveman is the top-tier symbol followed by a white sabertooth tiger, a dinosaur and a mammuth. There is no wild symbol in this game, as mentioned above, and everything revolves around the Mega Hold & Spin feature.

The Mega Hold & Spin bonus game is triggered when you land 3 scatters anywhere on the same spin, and the feature plays out on a brand new 10x10 grid. Only different color rock symbols or blanks will land, and the blue, green, yellow, pink and red rocks are worth 0.1x, 0.2x, 0.4x, 0.6x or 1x your stake, respectively.

The feature is upgraded by landing more than 3 triggering scatters however, as 4 triggering scatters remove the lowest value blue rock, while 5 triggering scatters remove both blue and green rocks for the duration of the bonus round.

You start with 3 respins, and all rocks that land becomes sticky on the 10x10 grid. You only need to lock 1 single rock in place to reset the respins tally to 3 again, and the feature goes on until you either fill the grid completely or run out of respins.

Larger 2x2 or 3x3 rocks are generated if you land clusters of matching 1x1 rocks, and these larger rocks come with a random prize. The 2x2 sized rocks come with prizes between 5x and 10x, while the 3x3 sized rocks award prizes of 35x to 500x. In addition, some rocks may land with keys attached, and these keys are collected in the mystery modifier trail to the left.

Mystery Chests are unlocked as you move along the trail, and these award the following extras:

  • A random rock is boosted by a random multiplier between x0.5 and x500.
  • An instant cash prize between 10x and 500x your stake is paid immediately.
  • Between 4 and 10 keys are added to the trail immediately.
  • A random multiplier between x2 and x100 will boost your total win from the bonus round.
  • A retrigger of the feature gives you a fresh start once the current feature is finished.

The chests open when you’ve collected first 3, then 4, keys, and you need 11 keys to reach the end of the trial Mystery Multiplier (the trail then resets and starts anew). The latter reveals a multiplier between x2 and x100, and it will boost the total stake multiplier prize you’ve currently racked up. If you fill the grid with sticky stones, the Hold & Spin feature retriggers with everything reset.

The 200 Spins Rock Vegas Slot Experience

had plenty of bonus teasers in the base game, and you get to see a few of them. You can safely skip to the 0:50-mark however, as that’s when the Mega Hold & Spin feature finally triggers. We managed to fill the whole grid and reach the end of the trail, and we thus got a second chance as the feature retriggered. See it all for yourself by hitting the play button below.

Review Summary

There is something dated about the visual presentation that we didn’t really like all that much, but you could stretch it to say that it combines okay with the prehistoric theme. We guess the ‘Rock Vegas’ title refers to the ‘stone age casino’ you’re taken into as the bonus round triggers, but the base game is a tedious dead-spin and top-up-win grind. All the bonus teasers get a bit annoying after a while too, but the feature itself was quite refreshing and fun.

First of all, the 10x10 grid makes it stick out from the run-of-the-mill Hold & Spin features, and so does the merging multi-colored stone cash symbols. We also like the key collecting system, awarding very useful extras like retriggers, extra keys and multipliers. The 10,000x potential is also solid enough, not least considering the decent 1 in 2,578,648 max win probability. We would hardly play Rock Vegas for the base game, but the bonus round might hit home with a certain crowd.


  • 10x10 grid Hold & Spin w/ key collect modifiers
  • Mystery total win multiplier up to x100
  • 10,000x potential (w/ 1 in ~2.57m probability)


  • Base game is a barebones grind
  • Beware of customizable RTP ranges

1 Million Megaways BC - is a popular caveman release from Iron Dog, and tumbling wins can lead to up to x8 multiplier boosts in the base game. The expanded grid bonus round comes with sticky wilds and a progressive multiplier, and this can lead to payouts up to 45,000x your stake.
