Forget about Pirots and other characters, as here we meet a new set of builders and HR Karen, introducing some new features while using the popular CollectR mechanic.
Lengthy win sequences that sometimes don’t lead to much
Concrete Cowboys Slot Overview
The CollectR mechanic is one of the reasons why the Pirots slots have become so hugely popular. Game developer ELK Studios has also used this in other slots, for example, Huff N’ Puff CollectR and Spark of Creation.
Concrete Cowboys follows in the footsteps of those games as the four builders collect the gems in their matching colours, and there are a bunch of extra features and shenanigans to explore.
The max win in Concrete Cowboys is 10,000x the bet, and the game is scheduled to be released in the UK on September 24, 2026.

The builders and HR Karen are set on top of a building where the game area is located.
It reminds me of the Pirots slots in some ways, but it is also a standalone slot.
The graphics are good and create a pleasant vibe. It’s quite spot on for the theme.
How to Play Concrete Cowboys
Concrete Cowboys plays on a 5×5 grid using the CollectR mechanic.
Builders collect gems that match their colours and are reachable. These symbols can be upgraded, and there are also plenty of extra features, mini-games, and free spins to explore.
You can play Concrete Cowboys with bets from 20p up to £5 when playing at UK online casinos.
Max bets per age group in the UK:
Aged 18-24: Maximum stake of £2 per spin.
Aged +25: Maximum stake of £5 per spin.
RTP, Volatility & Max Win
Concrete Cowboys might look all friendly, but this is actually a risky and highly volatile slot, so always play it responsibly. However, when luck strikes, you might win up to 10,000x the bet.
Concrete Cowboys is released in five RTP versions: 87%, 90%, 92%, 94%, or 96%.
Update: At the time of updating this review, our research shows that UK casinos, such as BetMGM and LeoVegas, offer Concrete Cowboys with an RTP of 94.00% in the United Kingdom.
However, other casinos offer a lower-RTP version of the game, with an average payout of 92.00% or lower.

Why RTP is important when playing slots
Whether we like it or not, the Return to Player, or RTP, of a slot significantly impacts a lot of crucial elements that come with playing slots.
The RTP is another term for the average percentage that a slot pays back for each stake. So, when a slot has a 96% RTP, it will pay back, on average, 96p for each pound staked. As you can imagine, the higher the RTP, the better it is for you, the player, as this will result in:
More spins before your money runs out
More spins = more chances to win
Increased playing time for the player
More value for money for the player
A lower profit margin for the casino
History of RTP and online slots
In the “old days”, all online slots had a default RTP, meaning the Return to Player was the same for each slot, no matter which online casino you played it in. However, since around 2020, due to regulations, increased Gambling Taxes and rising costs, online casinos started pressuring slot providers to release slots with different RTP configurations.
In effect, the online casino now had a choice: it was now able to offer its players a lower-paying RTP version. You could be playing a specific slot with a 96% RTP at casino A, and play the same slot with a 94% RTP at casino B, without even knowing it. The slot may look and feel the same, but the maths model underneath, which is the heart and soul of a slot, may be different, with all the negative consequences that come with it.
An example in real numbers
To illustrate the difference between playing a high-RTP slot versus playing the same slot but with a lower RTP, we have done some calculations.
Let’s take, as an example, one of the most popular online slots ever made: Book of Dead by Play’n GO. It has five possible RTP configurations: 84.18%, 87.25%, 91.25%, 94.25%, and 96.21%. Of course, other slots have different payout percentages, so results will vary.
We have calculated for Book of Dead, per RTP configuration, how many spins it takes to run out of money, based on theoretical losses (house edge) per spin, a starting balance of £100 and a stake of £1 per spin.
Book of Dead RTP
Theoretical Playtime
House Edge
96.21%
2,612 spins
3.79%
94.25%
1,721 spins
5.75%
91.25%
1,131 spins
8,75%
87.25%
776 spins
12.75%
84.18%
625 spins
15.82%
As you can see in our calculations, there are huge differences in the number of spins when you compare the different RTP configurations. The difference between the 96.21% RTP and the 94.25% RTP version is over 900 spins!
Conclusion
Playing with a higher Return to Player increases your chances of winning and playing time. So, when you want to play an online slot, always try to find a casino that offers it at the highest payout setting.

Slot Features & Bonus Rounds
Concrete Cowboys offers plenty to explore between its sometimes longer win sequences.
Progress Bar
Collected gems and wild symbols fill the progress bar, and once filled, it releases a wrecking ball that removes symbols from the grid and might kill characters.
The meter fills by collecting 20, 30, or 40 symbols, but it resets once the spin ends.
Special Features
Collecting these special symbols triggers the various features.
Upgrade: Collecting the upgrade symbols increases the levels/values of the gems.
Dynamite: Dynamite explodes all symbols in a random direction and can even kill collectors.
Transform: Changes an adjacent symbol cluster to the active collector’s colour.
Coin: Instantly pays the amount shown times the current bet.
Tunnel: Allows a collector to travel to another symbol cluster of their own colour.
Walkie Talkie: When collected, calls HR Karen to replace a random collector on the grid.
Wild: Substitutes for any colour paying symbol.
Level Up: Expands the grid by 1 row and 1 column and triggers a redrop.
Mini Games
Employee of the Month: Triggers when all paying symbols have been collected. Ladder symbols then allow collectors to climb up one level of the building to reach wins.
Building Time: Triggers when the Building Time symbol is collected. Reach higher rows to get higher multipliers.
Heaven Game: A maxed 8×8 grid with all paying symbols at level 7 is triggered when all 4 collectors are killed.
Free Spins
Collecting 3 bonus symbols trigger the bonus game with 5 free spins.
Symbols & Payouts
Concrete Cowboys features 4 regular pay symbols.
These symbols can reach up to 7 levels.
The lowest-level paying symbols can pay up to 0.10x the bet for each collected gem.
The highest-level paying symbols can pay up to 12.50x the bet for each collected red gem.
CasinoWizard’s verdict: Concrete Cowboys might become ELK Studios’ new franchise (7.5 out of 10)
When you play a slot like Concrete Cowboys, it’s hard not to compare it to the Pirots slots.
It does manage to capture some of that charm seen in those popular slots, and there is an adventure vibe happening here too. The game feels feature-rich, with various things to explore, including the different game modes “Employee of the Month”, “Building Time”, and the “Heaven Game”.
You also get all the extra features commonly used in CollectR slots.
I doubt Concrete Cowboys will reach the popularity of the Pirots slots, but it could still become its own series, as it has that potential. It also makes sense that ELK Studios is trying different ways to use the CollectR mechanic instead of diluting the Pirots brand with too many new releases.
The main concept is brilliant, and Concrete Cowboys is likeable while trying some new angles and features, so I don’t see why this won’t succeed as well. It’s really fun to play.
Final verdict: 7.5 out of 10.
Concrete Cowboys is officially released on September 24, 2026.
