Graphics, Music, and Sound Effects

What we have on the visual side of this game is not something you can see in any other slots. This time, we have unique illustrations in specific dark colors. Players will also find dark reel positions and a white frame. The urban area with tall buildings dominates the background. We also have animated electric sparks to spice up the atmosphere.

As expected from a game with a theme like this, users can listen to a piece of upbeat music with excellent guitar/rock music. We noticed the music was a bit louder, making sound effects unnoticeable.

Key Game Features

Our Rock Bottom slot review continues with the most critical aspects of this game – the key game features. This is also the most significant part of this review which makes sense because the crucial features will probably make you try or avoid this title.

The slot games we reviewed included various features, and Rock Bottom is no different. To get more precise info about these things, check the following paragraphs.

Theme – Urban/Dark

Once we loaded the Rock Bottom slot, we noticed the resemblance with the Joker movie. The slot's story involves a character going through the five stages of grief, and to go through this process, he has to fight his demons. As we said, there's a dark urban setting in this game that will make you feel uncomfortable yet attracted to it.

They say the best way to learn about the game's theme is to check the icons. This release has ten standard symbols, including five playing card icons with silhouettes. It also has five characters: a Stalker, a Hustler, a Pimp, a Prostitute, and a Joker/Clown. They represent the five stages of grief: denial, anger, bargaining, depression, and acceptance. Remember that the Joker is the icon with the highest value promising prizes worth 0.5 to 7.5 times the player's bet.


The reels of the Rock Bottom slot are not typical, but not because of the number of reels since it has standard 5 reels. The difference is in the format of rows. So, you can expect 3-4-4-4-3 rows starting from the leftmost reel


We also can't say that this game has a standard number of paylines because it doesn't have paylines at all. Instead, this slot features 576 ways to win, which is also not typical for releases with a ways-to-win mechanic. Players can expect to get paid when they land three, four, or five standard icons of the same type on adjacent reels.


As you might be aware, RTP stands for Return to Player percentage. This theoretical payout rate suggests the possible amount you can expect returned after a long period of spinning. The RTP of Rock Bottom is 96.04% which means that it's higher than most slots.

You can find online casinos where the RTP for this title is higher or lower. This is logical because online casinos are allowed to change these figures. Since there are dozens of sites where you can play Rock Bottom, we created a table where several excellent brands offer this title and its RTP values. 

Before signing up at any of these options, check the casino welcome bonuses and deals (including promo money, free spins, etc.), the selection of casino games, licenses, customer service, banking methods, and more. These things impact your experience as a real money player.

Also, the table above features the best gambling websites where users can try NetEnt's Rock Bottom. Of course, there are other slot sites we recommend for a memorable gambling experience.

Stake Range

With Rock Bottom, you get 25 betting values to choose from. We like how both low and high bets are available to users. We're talking about the lowest stake of £0.2 and the top bet of £100 per spin.

Max Win

The max win amount is another thing that makes this release a good choice. Namely, the max win amount is capped at 19,960x the stake.


The xSplit symbol (and feature) is found in many other Nolimit City slots and is one of the most exciting things in Rock Bottom. You can hit it only in the base game on the central three reels. Once it appears on any reel position, it will split itself, plus the character icons on that row in the central reels and the adjacent positions on the first and last rows. Remember that the xSplit icon will turn into two Wild icons capable of replacing missing standard symbols.

Also, the xSplit symbol can split characters up to 3 times, turning them into size 2, 4, or 8 icons.

Free Spin Modes/Scatters

The image of a bottle of Alcohol and Pills is a Scatter icon. Players will activate free spin modes when they land three or more of these symbols anywhere in view. Here's what you get: 

  • 3 or 4 Scatters – launch 5 Headshrinker Spins
  • 5 Scatters – launch 5 Insanity Spins

Users get one additional spin for every Scatter nudge to get to the bottom row. Let's not forget that the Scatter serves as a Wild.

As for the Headshrinker Spins, you can expect 5 stages with 5 characters linked to each stage. The related character expands to cover the reels during their stage. Characters that have not reached their stage yet appeared on the reels will increase their multipliers by one. You must gather five Scatters to reach the next level, providing two additional spins. Finally, every Scatter delivers one extra spin.

On the other hand, the Insanity Spins work similarly to the Headshrinker Spins. Still, instead of expanding character symbols, the characters become expanding Wilds. Furthermore, the multipliers of two or more characters can be added together and applied to the player's wins for extraordinary rewards.

xCap: Downfall

Players who get winning combinations worth 1,969 their total bet in a single turn will activate the xCap feature. They get an opportunity to unveil a random multiplier of 2x to 10x. After that, the revealed multiplier is applied to the win. So, you can expect to get between 3,938 and 19,690 times your total bet in the end. As mentioned earlier, the latter is the maximum win amount of this game.


Some games include a single winning combo that can help players win the highest possible reward in the slot. Rock Bottom is not among these releases, so you can't expect a direct jackpot prize here. Those who want to check the best jackpot slot games should open our page where such titles are listed.

Play Experience & First Impressions

This game's mood might make you depressed, but things will change once you press the play button. Honestly, we would like to see more frequent wins and higher winnings in the base game because they were not regular and rarely went above 1 time our bet. 

If it weren't for the xSplit feature, which occurred three times during our 100-spin test, the RTP would be much lower than 76.6%. Still, we must point out that the xSplit feature has great potential, promising big rewards in a matter of seconds.

As we said, the visuals and story are unusual and unique. We liked the animations after the bonus features were activated. We didn't launch any of the two free spin modes, which would certainly affect our gaming experience positively.

100 Spins Test

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Element Outcome
Session RTP 57.15%
Win Frequency Medium - High 33/100
Biggest Base Game Win 10x
Spins to Bonus n/a
Bonus Paid n/a
Time Taken for 100 Spins 8.10

If you have never played a NoLimit City slot before, what I am about to say may shock you, but that felt like a decent session on the slot.

The 33 winning spins in 100, is a higher percentage than is often achieved on Medium volatility slots, but where NoLimit comes into play here is the paltry 57% RTP with 'Winning' spins averaging only £1.73, and the biggest base game win being 10x.

Even then, I don't feel hard done by, as NLC can swipe you harder than 57% over 100 spins.

It' was fairly rapid too, taking just under 8 minutes to complete, and if I am perfectly honest, half the time I had no idea what was going on, but I do recall two bonus baits during the game. But, Alas, the bonus didn't land on this occasion.

I can tell you from previous experience that the bonus round is as confusing as you would expect from any NoLimit City slot game, and as such, it is like the proverbial rollercoaster where shut your eyes, hang on tight and see what the result is at the end is the way forward.

Expert Verdict

With the Rock Bottom slot, you will enter a mysterious urban world where danger and excitement hide around every corner. This game has a decent RTP of 96.04%. In addition, it's a high volatility title (we have witnessed that in our trial test).

With 5 reels and 576 ways to win, it's relatively unique, but what makes it special is the carefully designed bonus features that can help players win excellent prizes. We will also mention the memorable illustrations, music, and unique story. Rock Bottom might not be among the best paying slots, but it's a real treat for players who like eccentric games.
