Case Closed (Red Tiger Gaming) Slot Review

Case Closed: Slot Overview 

Crime-solving meets reel-spinning in Case Closed, a highly original online slot game developed by Red Tiger. Released on September 19, 2023, Case Closed ditches high-speed chases and blazing guns for something more methodical — an old-school, noir-tinged detective experience where clue collection, interrogations, and solving cold cases take center stage. 

Set in a detective’s office, this 5-reel, 4-row slot with 50 paylines runs on a high volatility model, with a solid RTP of 96.02% and a generous hit frequency of 5/5. Instead of a typical bonus round, Case Closed builds tension through its interrogation and evidence mechanics, allowing players to progressively unlock higher rewards as they “solve” criminal cases. While the maximum win of 2,640.2x the stake may not reach astronomical heights, it fits well with the game’s grounded, procedural format.

Design and Graphics 

Case Closed delivers a cozy, characterful setting for its sleuthing action — a dimly lit investigator’s office filled with papers, phones, case files, and a slightly worn-down aesthetic that perfectly suits its theme. The reels are housed in a tan corkboard-style background, flanked by silhouettes of suspects on the left and unsolved case folders on the right. It’s a quiet but effective presentation that evokes vintage police dramas without veering into parody or cliché.The symbols reinforce this investigative vibe, featuring everything from old-school detective badges and pistols to getaway cars and suspects in shadow. While the color palette leans muted, it’s consistent with the setting, and the symbol artwork has a charming, almost comic-book feel. There’s no high-gloss polish here — it’s all about atmosphere, and Case Closed delivers just the right balance of grit and clarity.

Gameplay Mechanics 

Unlike many modern slots packed with feature overload, Case Closed favors a simpler, more linear gameplay structure. The game plays out across 5 reels with 4 rows, offering 50 fixed paylines. Wins pay from left to right, starting from the first reel, and most symbols require at least three of a kind, though two of the top-tier symbols only need two to score a win. 

Bets range from 10 p/c to £/€20 per spin, making it accessible to a wide audience. A hit frequency of 54.01% means wins come frequently, even if the base payouts aren’t massive — a key trait that helps maintain engagement over longer sessions. The symbols are divided into low-paying 10–A royals and four high-paying icons: a badge, pistol, car, and a male suspect. The top payout from standard symbols reaches 6x the bet for a five-symbol combo, though special feature symbols (and suspect interrogations) are where the big wins lie. 

Interestingly, there are no wild symbols in Case Closed, which is unusual in a modern slot, but this absence reinforces the thematic choice to rely on clue gathering and case solving rather than conventional mechanics.

Sound and Music 

Audio design in Case Closed is low-key but purposeful. There’s no constant musical backdrop; instead, atmosphere is built through ambient noises and occasional, gruff detective voiceovers that channel your inner hard-boiled sleuth. The absence of persistent soundtrack music actually works in the game’s favor, allowing the player to focus on the gameplay and creating a slow-burn, immersive mood that echoes the pacing of a real investigation. 

Sound effects are clean and thematic — pages flipping, phones ringing, and case files thudding shut. These minor details help maintain the illusion that you’re solving mysteries rather than just spinning reels.

Bonus Features 

Rather than a conventional bonus round, Case Closed introduces two clever interlinked features: Interrogation and Case Solving, both of which unfold within the base game for seamless integration.Clue Symbols and the Interrogation Feature 

The Clue symbol — marked by a magnifying glass — is central to the Interrogation feature. It lands on reels 2, 3, and 4, and is collected when it appears. Once 7 Clues are gathered, the Interrogation feature triggers. 

To the left of the reels are three suspects, each displaying a cash prize amount (which can change per spin): 

Suspect 1: 5x, 10x, or 15x the bet 

Suspect 2: 25x, 30x, 40x, 50x, or 75x 

Suspect 3: 100x, 150x, 250x, 350x, or 500x 

The interrogation begins with the first suspect. Outcomes are randomly successful or unsuccessful. If successful, you win the prize and move to the next suspect. If you fail, the feature ends. This layered approach adds risk and anticipation, creating one of the more innovative reward systems in Red Tiger’s portfolio. 

Evidence Symbols and the Case Feature 

On the right side of the screen sit three unsolved case folders. These are completed by collecting Evidence scatter symbols, which appear only on the center reel and at most one per spin. Each time one lands, it’s added to your tally. Collecting 10 solves a case and provides permanent benefits: 

Solving the 1st case: Guarantees the first interrogation is always successful 

Solving the 2nd case: Reduces Clue requirement from 7 to 5 Clues 

Solving the 3rd case: Unlocks a fourth suspect, worth 2,000x the bet, but only interrogated if the first three are successfully questioned 

These progression-based rewards add long-term goals to the gameplay, allowing players to build toward more lucrative outcomes over multiple sessions.

Betting Options and Payouts 

With a minimum bet of £0.10 and a maximum of £20, Case Closed is welcoming to most players, though the max stake may be too conservative for high rollers. What it lacks in high betting flexibility, it makes up for with its frequent hits and progression-based mechanics. 

While the maximum win is 2,640.2x the stake, this is relatively modest compared to many Red Tiger titles. However, the game’s consistent payout structure and feature engagement make this total feel both achievable and worthwhile. Crucially, the RTP of 96.02% is slightly above average for Red Tiger slots, making it appealing to strategy-focused players looking for value in long play sessions.

Conclusion 

Case Closed may not be the flashiest game on Red Tiger’s roster, but it stands out for its thematic cohesion, clever design, and emphasis on progression over spectacle. It swaps high-octane thrills for a more methodical, narrative-driven experience, where rewards are earned by solving cases and interrogating suspects — not just spinning blindly in search of scatters. 

While the absence of a traditional bonus round or wild symbols might turn away some players looking for explosive features, Case Closed makes up for it with a compelling feature set, constant engagement via clue and evidence collection, and a relaxed, noir-detective aesthetic that’s both immersive and distinctive. 

For fans of crime-themed slots like Cash Noire or The Great Stick-Up, Case Closed offers something a little different: a slower-paced, story-driven experience with solid payout mechanics. Its low-stress presentation and high hit frequency make it a strong option for casual players and Red Tiger fans looking for something fresh. 

In short, if you’re ready to put your sleuthing skills to the test and interrogate your way to some decent wins, Case Closed is one mystery worth investigating.
