The Crime File (NowNow Gaming) Slot Review

The Crime File: Slot Overview

Anthropomorphised dogs running a crime-riddled city is exactly the kind of left-field concept that earns a second look. NowNow Gaming released this noir detective slot in June 2026, building a 5×4 reel format around a multiplier-stacking system that does the heavy lifting throughout both the base game and the bonus. Detective Rex is your guide, the canine criminals are your quarry, and wins up to 10,000x are the prize at the end of the chase.

This one sits squarely in medium-volatility territory. Players who want regular feedback without the grinding drought of high-variance machines will feel at home here. High-roller bonus hunters get a feature buy option too, so the slot covers more ground than its modest payline count might suggest.

Design and Graphics

NowNow Gaming sets the scene with a dark urban backdrop — concrete walls washed in reddish ambient light, a smoking pipe resting on a round table, and a gun-toting dog thug lurking on the right side of the screen. It reads noir immediately. The atmosphere lands. But it doesn’t go much further than that first impression.

The background stays static throughout. When the Interrogation Bonus triggers, the lighting shifts slightly, and that’s about as dramatic as the visual transformation gets. For a theme built on investigation and criminal pursuit, that’s a missed opportunity.

Where the design earns its keep is on the premium symbols. The four character portraits — three canine criminals and a police officer — are rendered with real detail and personality. Each one has a distinct look and feel. You can tell the studio spent time here. The low-pay symbols, by contrast, are just card suit emblems and a pentagon shape. Generic filler, no other way to describe them.

The Wild — a circular open jaw — looks appropriately menacing when it expands up the reel. The animation is clean and purposeful. Sound design runs a tense, atmospheric track that suits the mood well for the first session. Give it a few hours and it starts blending into the background.

Gameplay Mechanics

You need three matching symbols starting from the leftmost reel on one of the 14 paylines to register a win. The grid runs five reels across four rows, and the base game flows cleanly with no friction. Spin, watch the reels, see if anything connects.

Low-pay symbols return between 1x and 1.5x your bet for a five-of-a-kind. That’s minimal. High-pay portrait symbols jump to a much healthier 5x to 10x for five across a payline, and the Wild pays 50x for a full five-symbol line by itself. The gap between the low and high end of the paytable is sharp — this game really does want you chasing the premiums.

Two base game mechanics run alongside the standard spin cycle. The Hunt triggers whenever a Wild lands and has a chance to form part of a winning combination — it expands upward and picks up a multiplier based on how far it stretches. The Capture activates when any high-value symbol fills an entire reel as a stack, handing out a 2x to 10x multiplier on the round’s total win even if that stacked symbol isn’t part of a paying combination.

Both multipliers feed into a Total Multiplier meter that sits outside the grid. When multiple multipliers trigger in one spin, they combine and apply to the entire payout from that round — not just to individual winning lines. That design choice makes a genuine difference when things stack up.

The hit frequency sits at 27.3%, meaning roughly one in four spins returns something. For medium volatility, that feels about right. You won’t feel completely abandoned between features.

Bonus Features

Land 3, 4, or 5 Scatter symbols — represented by a red retro car — anywhere on the reels in a single spin, and you trigger the Interrogation Bonus with 10, 15, or 20 free spins respectively. The bonus inherits both The Hunt and The Capture mechanics. The key difference is that every Wild in the free spins round expands to cover its entire reel automatically. That locks in the highest possible multiplier range for every Wild that appears — up to 100x from a single fully expanded Wild.

There’s one gap that stands out: no retrigger. Once you’re in the bonus, those scatter symbols disappear from the reels. You play out your spins and that’s that. Given the whole game runs on multiplier accumulation without a persistent carry-over value, the bonus can deliver big when Wilds appear frequently, but it can also feel flat when they don’t.

No persistent multiplier builds across the free spins. That feels like a deliberate design choice, but it means the bonus relies entirely on variance within those 10-20 spins to reach its ceiling.

Three Feature Buy options let you skip the wait if you prefer direct access.

Betting Options and Payouts

Bets run from €0.10 to €100, which covers casual players and serious mid-stakes action without pushing into ultra-high territory. At RTP 96.33%, the default version is solid — right in line with what you’d expect from a quality release. A second variant at 94.22% RTP also exists, and that gap is significant over volume. Always confirm which version your casino runs before you commit sessions to it.

Medium volatility at 27.3% hit frequency means the game plays patiently but not punishingly. You’ll see returns regularly enough to stay engaged. The real question is whether the multiplier system fires when it matters. A fully expanded Wild with a 100x multiplier on top of a Capture multiplier during free spins is where the 10,000x max win starts making theoretical sense — but getting there requires both mechanics to align in a single bonus round, which isn’t guaranteed.

For casual players, the medium volatility profile makes €0.10–€0.50 stakes a comfortable session range. Bonus hunters using the 100x Feature Buy need to factor that cost against the bonus’s inability to retrigger — the risk-reward calculation is tighter than it first appears.

Conclusion

NowNow Gaming built something coherent here. The multiplier system is the real product — two distinct delivery mechanisms that combine cleanly and scale well when both fire together. The Hunt’s expanding Wilds do most of the damage, while The Capture adds a stacking layer that doesn’t require winning combinations to activate. That combination is genuinely interesting design.

What holds the game back is the surface level. The noir dog-detective concept has room to go much deeper, and it doesn’t. A shifting light filter for the bonus round is the extent of the visual evolution. The low-pay symbols are placeholder quality. No retrigger in the bonus is a genuine limitation for players chasing that 10,000x ceiling.

The 96.33% RTP is worth protecting — always verify the version you’re playing before locking in a session. And the 100x Feature Buy into a non-retriggering bonus needs careful consideration at higher stakes.

Players who want a clean, functional medium-volatility game with real multiplier potential and no gimmicks will find this rewarding. Players who need strong visual storytelling or progressive bonus complexity to stay engaged will find it thin. Players can test the slot risk-free using the built-in demo available on this page.
