Case Closed RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 50 Paylines

Stakes Range: 10p to £200

Max Win: 2,640 x stake per spin

RTP: 96.02% | 93.22% | 95.18% | 91.07%

The Case Closed slot is played over 5 reels, 4 rows and 50 paylines. To create a win, you must simply land 3 or more matching symbols on adjacent reels, from left to right, along a payline. The exception to this is the 2 highest value symbols, which only require a minimum of 2 matching symbols.

You can play the Case Closed slot for as little as 10p, up to £200 per spin. This is a wide betting range, though this isn’t unusual for Red Tiger Gaming slots. To adjust your stake, use the + and – buttons below the reels. Here you’ll also find Autoplay and Turbo options, if you’re playing from outside of the UK.

Case Closed has an RTP rate of 96.02%, which is slightly higher than average. That said, the RTP rate can drop as low as 91.07% depending on the version. For the most rewarding experience, make sure you only play at trusted UK casinos.

The slot also boasts an extremely high volatility (5/5) and a high hit frequency rate too. Red Tiger haven’t shared the actual percentage for the hit frequency rate, but they also judge it as 5/5.

Finally, Case Closed boasts max wins of 2,640 x your stake. Bigger wins come via the Case feature, which in turn leads to boosted Interrogation multipliers. We’ll dive into this later in this review,

Theme – noir detective crime caper

Theme: Detective

High Value Symbol: Detective

Compatibility: Mobile, Tablet, Desktop


As the name suggests, Case Closed has a detective theme. The reels hang against a dim lit, and slightly shabby office, giving it a film noir vibe. It’s similar in look to Brooklyn Bootleggers by Quickspin, though all of the action takes place at the detective’s desk.

On the reels, low paying symbols include 10 to Ace royals. Higher value symbols include a badge, a car and a gun. The detective is the highest paying symbol, rewarding you with 400 x your stake for a 5-of-a-kind combination.

Case Case closed does not feature a wild symbol. Instead, there are two scatters, Evidence and Clue, which can be collected to trigger bonus features.

Case Closed mobile


Like all Red Tiger Gaming slots, Case Closed is optimized for desktop, mobile, and tablet play. The simple 5×4 layout translates well to smaller screens, and HTML5 technology ensures flawless gameplay on both iOS and Android smartphones.

Case Closed Bonus Features

The Case Closed slot comes with 2 bonus features. This includes an Interrogation feature which comes with multipliers, and a Case feature which boosts your chances at winning big in the Interrogation feature.

Cases Feature

When you load the Case Closed slot, you’ll see there are 3 case folders to the right of the reels. To unlock these, you need to collect Evidence symbols, which can land on the middle reel only. You need 10 Evidence symbols to solve each case.

Each case you solve boosts your Interrogation feature:

  • Case 1: Guarantees Suspect 1 interrogation is successful
  • Case 2: Reduces Clues needed to trigger Interrogation from 7 to 5
  • Case 3: Unlocks Suspect 4 who awards a huge 2000x win if successfully interrogated

Naturally, then, solving all 3 Cases gives you the best chance at bigger wins during the Interrogation bonus. Let’s see how that works…

Interrogation Feature

To the left of the reels, you’ll see 3 suspects. To start the Interrogation feature, you need to collect 7 Clue symbols, which can land on reels 2, 3, and 4. When triggered, you’ll interrogate 3 Suspects that have random instant cash prizes attached to them, based on the following multipliers:

  • Suspect 1: 5x, 10x or 15x
  • Suspect 2: 25x, 30x, 40x, 50x or 75x
  • Suspect 3: 100x, 150x, 250x, 350x or 500x

Each interrogation’s result (successful or unsuccessful) is random. On a successful interrogation, you win that Suspect’s prize and move to the next Suspect. The feature ends on the first unsuccessful interrogation or when all Suspects are successfully interrogated.

RTP (96.02%)

Max Win (2,640 x)


A dectective-noir themed slot is nothing new, but we think Red Tiger Gaming have pulled it off nicely in terms of appearance. The design is good, and the features push the narrative. However, they can be a little underwhelming.

The Case Closed slot is easy to follow and there’s some innovation in the way the bonus features work. However, given the high volatility of the slot and the fact you need to collect several scatters to trigger anything, you can spin for a while without any action.

The highest prizes are locked away behind 30 Evidence scatters. Land these, and you’ll then need at least 7 more Clue scatters to unlock the high multipliers. As this is your chance at reaching those 2,640 x bet max wins, it can feel like a lot of effort for not much to begin with.

Overall, we enjoyed the story of the Case Closed slot. We wish it was a little more fast-paced, however. Another feature such as free spins or cascades would be useful, allowing you to rack up clues in fewer spins.

If you’re a fan of the crime movie genre, try Narcos Mexico, also by Red Tiger Gaming. Based on the TV series of the same name, this slot boasts fantastic graphics, 243 ways to win, and 10,486 x stake max payouts.
