Step into the comic-book noir world of Criminal Circles by 7Rings Gaming. This 5-reel, 20-payline slot ditches free spins for “Guaranteed Wins” and introduces a unique “Field Extension” mechanic.

Criminal Circles Slot: Key Features Overview
The Criminal Circles game operates on a 5-reel, 20-payline structure, but its gameplay is defined by its special features. The main attractions are the Field Extension mechanic, which expands high-value symbols, and a bonus game that replaces “free spins” with “Guaranteed Wins,” ensuring you get value from the feature.
Summary of Bonus Features
| Feature Name | Description | Trigger / How it Works |
|---|---|---|
| Field Extension | Expands a high-value symbol to cover its entire reel. | Land a high-value symbol in a winning combo that matches the symbol in the Activator Cell above its reel. |
| Arrest Symbol | A special symbol that acts as a Wild. | Lands on any reel and replaces the symbol in the Activator Cell, then acts as a Wild, taking the form of that cell's symbol. |
| Guaranteed Wins | Bonus round where spins are not counted unless they result in a win. | Land 3 Scatter symbols (Revolver Chamber) on reels 2, 3, and 4. |
| Buy Bonus | Two options to purchase direct entry or modified triggers. | FS BOOSTER 5x: 5x odds of Scatters. RANDOM LUCK: Guarantees random Bonus symbols. |
What is the Field Extension Mechanic in Criminal Circles?
The Field Extension mechanic is the core engine of the base game. It provides a multi-stage win calculation: wins are first calculated before any expansion, and then calculated again after the expansion, potentially creating new or improved winning lines.
This mechanic centers on the Activator Cells positioned above each of the five reels. In every spin, these cells display one of the high-value character symbols.
How Activator Cells and Symbol Expansion Work
To trigger the Symbol Expansion, two conditions must be met simultaneously:
- A high-value symbol (one of the five characters) must land on the reel.
- This symbol must be part of a winning combination.
- The symbol on the reel must match the character symbol in the Activator Cell directly above it.
When all three conditions are met, the mechanism activates. The high-value symbol expands to cover the entire reel, and this expanded reel is counted as 3 of the same kind during the win count. This can be triggered on multiple reels in a single spin, leading to complex and high-payout scenarios.
The Arrest Symbol: A Crooked Cop or a Wild Card?
The Arrest Symbol is a clever twist on a standard Wild. When this symbol (a silhouette in a mugshot) lands on a reel, it immediately replaces the symbol in the Activator Cell above it.
After replacing the symbol in the cell, the Arrest Symbol on the reel transforms. It takes the form of the symbol it just placed in the Activator Cell and now acts as a Wild Symbol for that spin. This dual-function makes it a powerful tool for both triggering the Field Extension (by forcing a match in the Activator Cell) and completing standard paylines.
How Does the Guaranteed Wins Bonus Game Work?
The bonus game in Criminal Circles does away with the concept of “free spins.” Instead, it provides a set number of Guaranteed Wins, which is a significant and welcome change. This feature is the primary objective for any player testing the Criminal Circles demo.
This design choice directly targets the main frustration of many bonus rounds: landing 10-15 spins that result in zero or minimal payouts. Here, the number of spins is irrelevant; only the number of winning spins matters.
Loading the Chamber: Scatters and Bullets
To trigger the bonus, you must land 3 Scatter symbols (which look like a revolver chamber) on reels 2, 3, and 4. This is the only place they appear.
Once triggered, an animation plays where the 3 Scatter symbols “start to spin bullets.” The total number of bullets from all three Scatters is summed up, and this number becomes your starting counter for Guaranteed Wins.
Why “Guaranteed Wins” Beats “Free Spins”
The rule is simple and powerful: the Guaranteed Win counter is reduced by 1 only if the spin results in a win.
If a spin occurs and there are no winning combinations, nothing happens. The reels spin again, and your Guaranteed Win counter remains unchanged. This continues until a winning combination lands. This completely alters the “rhythm” of the bonus, turning it from a gamble on spins into a countdown of confirmed payouts.
Vlad's Expert Tip: “Don't be fooled by a low number of Guaranteed Wins, say 5 or 6. That's 5 guaranteed winning spins. In a high-volatility game, a traditional '10 free spins' bonus can easily give you only 2-3 small wins. I'd take 5 guaranteed outcomes over 10 empty promises any day. This is where you should focus your testing in the demo.”
The Mathematical Paradox of Guaranteed Wins
Here’s the thing… this “Guaranteed Wins” system sounds fantastic, right? And it is, for the player experience. But it creates a paradox. You are guaranteed a win, not a big win. The game could, theoretically, discharge its obligation by giving you a 0.1x bet win, and it would count.
I suspect the volatility during this feature is dialed way up. The game knows it has to pay. The question is whether it will pay the minimum or if it will trigger the Field Extension feature, which is also active during the bonus. The entire round becomes a high-tension wait for that one spin where a low “guaranteed win” becomes a massive “Field Extension” cascade. It’s a brilliant piece of design, honestly… making you feel secure and terrified at the same time.
How Do You Play the Criminal Circles Demo?
The best way to understand these interconnected mechanics is by playing the Criminal Circles slot demo. The free play version gives you a full balance of “FUN” credits, allowing you to test everything without risk.
Playing the free Criminal Circles game is essential. You can learn the rhythm of the Activator Cells, see how often the Arrest Symbol lands, and, most importantly, try to trigger the Guaranteed Wins bonus to feel how it works. The Criminal Circles free play version includes all features, including the Buy Bonus options.
Testing the Buy Bonus Features Safely
The Criminal Circles game offers two Buy Bonus features, which you can test in the demo.
- FS BOOSTER 5x: This isn't a straight bonus buy. It modifies your bet to fivefold the odds of landing 3 Scatters. This is for players who want to accelerate the base game hunt.
- RANDOM LUCK: This guarantees a random number of Bonus (Scatter) symbols on the next spin, making it much more likely to trigger the feature.
Using the demo to test these is smart. You can see if the FS BOOSTER 5x feels like it provides value or if the RANDOM LUCK feature is a more direct path to the bonus.
Understanding the Paytable and Symbols
The paytable is split between high-value characters and low-value contraband. All wins pay left to right on the 20 fixed paylines.
- High-Value Symbols: The five characters. The Mafia Boss (red) is the highest, paying 25.00 for a 5-of-a-kind line (on a 2.00 bet, implying a 12.5x payout). He is followed by the Femme Fatale (20.00 / 10x), the Bouncer (15.00 / 7.5x), the Gunman (10.00 / 5x), and the Detective (6.00 / 3x).
- Low-Value Symbols: These are the tools of the trade: a BAR sign, a briefcase full of money, a crate of whiskey, and a getaway car.
Theme, Story, and Game Feel
This slot excels in atmosphere. It leans heavily into a Crime-noir aesthetic, looking like a page from a modern graphic novel. The Mafia and Heist elements are clear, but the comic-book art style sets it apart from more realistic gangster slots.
The dark city background and detailed character portraits create a strong narrative feel. You're not just spinning reels; you're inside a turf war. This game would also appeal to fans of Mystery slots or even Wild West themes, which often share this gritty, character-driven approach.
The Criminal Cast: Symbol Legend
| Symbol | Character |
|---|---|
| Boss (Red) | The Don. His appearance on the reels demands respect—and pays the most. |
| Femme Fatale (Purple) | The Dame. She's the second-in-command, holding secrets and high value. |
| Bouncer (Yellow) | The Muscle. A tough guy who guards the operation. |
| Gunman (Blue) | The Hitman. This trigger-happy character brings in the mid-level payouts. |
| Detective (Green) | The Fed. He's on the case, but he's the lowest-paying of the high-value crew… maybe he's crooked? |
Missing Intel: Criminal Circles RTP and Volatility
Here is the main issue with this slot: 7Rings Gaming has not provided public data on the Criminal Circles RTP (Return to Player), volatility, or Max Win.
This is a significant information gap. Based on the complex mechanics, the “all or nothing” feel of the Field Extension, and the high-potential Guaranteed Wins bonus, the game feels like it operates on a high volatility model. The payouts in the bonus round would need to be substantial to offset the base game. The 25x payout for the top symbol is low, which further suggests the game is entirely dependent on its features.
Vlad's Expert Tip: “When a developer doesn't release RTP or volatility, you must treat the game as high volatility by default. In the demo, manage your ‘FUN' balance as if it's real. See how many spins it really takes to trigger the bonus. Does your balance drain quickly between features? This will give you the answer that the paytable omits.”
The Problem with New Providers and Data
This lack of transparency is common with new or smaller studios like 7Rings Gaming. While it's understandable, it puts the player at a disadvantage. Without knowing the Criminal Circles RTP, you can't assess its long-term fairness compared to industry standards (which hover around 96%).
This is the strongest argument against playing the game with real funds until more data is available. It makes the Criminal Circles slot demo not just a good idea, but an absolute necessity.
Detective's Notes: Hidden Details
Beyond the main features, a few other details are worth noting:
- Leaderboard: The game includes a built-in Leaderboard with tabs for stats on wins, popularity, and performance. This is a social feature that lets you see how you stack up against other players over time ranges from 10 minutes to 7 days.
- Auto Play Conditions: The Auto Play function is robust. You can configure it to stop not just on a number of spins, but also if a Bonus Game is won, if losses hit a certain threshold, or if a single win exceeds a set amount.
- Win Display: The “WIN” display clearly shows any wins, which is important given the multi-stage calculation of the Field Extension.
Alternative Heists: Slots Like Criminal Circles
If you enjoy the theme and mechanics of the Criminal Circles slot, there are several other titles available on Respinix that hit similar notes.
- For the Gritty Crime Theme: Le Bandit by Hacksaw Gaming shares a similar character-driven, comic-book style, though its mechanics are centered on “Golden Framed” symbols and a “Rainbow” mechanic.
- For High-Stakes Bonus Rounds: The Money Train 3 slot from Relax Gaming is the king of high-potential bonuses. While its theme is more sci-fi, the “hold-and-win” bonus is a benchmark for high-volatility excitement.
- For Expanding Symbols: The concept of an expanding symbol transforming a spin is the heart of the “Book of” mechanic. The original Book of Dead from Play'n GO is a classic example. Criminal Circles takes this idea but makes the trigger (Activator Cells) much more active in the base game.
- For Themed Bonus Features: Wild West Duels by Pragmatic Play, while a Wild West slot, offers different types of bonus rounds, similar to how Criminal Circles separates its features.

Final Verdict on the Criminal Circles Slot
So, what's the final word?
I'm genuinely impressed with the core ideas from 7Rings Gaming. The Field Extension is an engaging and multi-layered base game mechanic. But the Guaranteed Wins feature is the real star. It's an innovative, player-friendly solution to the “dud bonus” problem. The art style is strong, the theme is coherent, and the whole package feels polished.
The problem is the complete lack of data. I can't recommend a slot without knowing its RTP or volatility. Therefore, my recommendation is strong but specific: You should play the Criminal Circles demo. Play it extensively. See if you can tame its volatility, understand its payout rhythm, and decide for yourself if this crew is one you want to run with. It's a fantastic design Caged by a mystery.
