Rock Vegas Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 20 paylines

Stakes Range: 20p to £240 per spin

RTP: 96.64%

Max Win: 10,000 x stake per spin

The Rock Vegas slot is played on 5 reels, 3 rows, and 20 fixed paylines. Winning combinations are formed by matching 3 or more symbols in combination from left to right, starting from reel 1.

Stakes range from 20p up to £240 per spin. You can adjust your bet but hitting the – or the + icon on either side of the spin button below the reels. There’s also an Autoplay button in this area too in some territories. You can use this to set up to 1,000 autospins as well as a turbo or quick spin option.

The Rock Vegas RTP is 96.64%, which is higher than many slots on the market and well above average. But with the variance here being extremely high at 5 out of 5, don’t expect big wins regularly. However, the chance to hit bigger wins in a shorter space of time is higher than slots with lower volatility.

The maximum win is 10,000 x your total stake. This is best achieved during the bonus feature due to the 500x multipliers in place. If you happened to hit a big win that could be higher than 10,000x, the round will end when it hits the maximum win limit.

Theme – Audio and Design Features – a prehistoric adventure

Theme: Jungle

High Value Symbol: Caveman

Compatibility: Mobile, Tablet, Desktop


The theme is a prehistoric one, with animals from the ice age and cavemen dominating the screen. The reels are set in a jungle, with a soundtrack giving a Jungle Book type feel to the gameplay. It also gives off a fun but mysterious vibe, with things getting more intense once the bonus feature lands.

The Rock Vegas slot game is certainly a game of 2 reels. The base game is your standard slot view that you see with many games. The bonus feature is completely different, with a 10×10 grid appear to the right, and a trail of keys and treasure chests on the left. The audio changes to a Rhythm and Blues nature, which makes for a pleasant experience.

On the reels in the base game, you’ve got your usual A-10 royals as your low paying symbols. These are accompanied by a mammoth, a raptor, a tiger, and a caveman. The caveman is the most rewarding symbol, paying 0.75, 7.5, 15 or 37.5 x your stake for 2, 3, 4 or 5 on a payline respectively.

The bonus symbol is a rock. It can hit naturally or appear randomly at the end of a spin. 3 or more of them will trigger the Megaw Hold and Spin feature in this Rock Vegas slot.

Rock Vegas Mobile


Created using the best HTML5 technology, you can play in the jungle on desktop, mobile and tablet devices. The 10×10 bonus feature setup makes for an enjoyable experience on smartphones and smaller devices.

Rock Vegas Bonus Features

There’s 1 bonus feature in the Rock Vegas slot game and it’s a great one. Let’s explain every aspect of it for you so that you know exactly what’s going on when you manage to trigger it playing yourself.

Mega Hold and Spin feature


Land 3 or more bonus symbols to trigger the Megaw Hold and Spin feature. A new 10×10 grid will appear, with the normal reels replaced by ones that contain just rocks and empty spaces. The rocks have fixed values as follows:

Symbol Value
Blue Rock 0.1x
Green Rock 0.2x
Golden Rock 0.4x
Pink Rock 0.6x
Red Rock 1x

Depending on how many bonus symbols trigger the feature, this will determine whether the lowest paying rock symbols are present or not.

  • 5 bonus symbols = only the orange, pink, and golden rocks are present
  • 4 bonus symbols = only the orange, pink, golden, and green rocks are present
  • 3 bonus symbols = all rocks are present

All rocks that land will stay in place until the end of the feature. Additionally, any that land will reset the respins to the original 3 that you get to begin with.

If you get a 2×2 or a 3×3 cluster of the same rock symbol, it will transform into a big rock and be given a random multiplier.

  • 2×2 cluster = between 5x and 10x multiplier
  • 3×3 cluster = between 35x and 500x multiplier

After each respin, there’s a chance for rock symbols to be randomly added to the screen with a fire animation.

To the left of the 10×10 grid, you’ll see a key collection mini-game. Rock symbols can land with a key symbol on them. These are then added to the collection. You can be awarded one of the following once you reach a chest:

  • A random rock symbol will be multiplied by between 0.5x and 500x.
  • A random direct money awarded from 10x  to 500x.
  • Receive between 4 and 10 keys randomly to add to the trail.
  • A multiplier between 2x and 100x will apply to the total win of the round.
  • A bonus feature retrigger.

If you manage to reach the Mystery Multiplier at the end of the trail between 2x and 100x is collected and multiplies the general multiplier you’ve got so far.

What’s great about this feature is that it can be retriggered from either a chest or by filling the whole grid with rock symbols.

RTP (96.64%)

Max Win (10,000 x)


The Rock Vegas Mega Hold and Spin slot is pretty basic in terms of gameplay during the base game. But once you land the bonus feature it’s a completely different story, with a new 10×10 grid appearing as well as a mini-game of collecting keys. It really does enhance the appeal of the slot overall as it’s a great bonus feature.

The audio is fun and should appeal to many. It’s not one of those that you’re quick to find the mute button for. Overall, we love the slot once the features kick in. Why not give our free demo a go first to see if you like it?

One slot that also has a caveman at the forefront of everything that’s happening is Playtech’s Jackpot Giant slot. This is well worth considering if you fancy average jackpot payouts of over £4 million. If you’re a fan of respins, give Jurassic Park: Gold by Microgaming a try. This Link & Win slot comes with an exciting respin feature with 4 jackpots up for grabs.

  • 10,000 x stake max wins
  • Higher than average RTP (96.64%)
  • Great bonus feature
  • Highly volatile (5/5)
