It’s a Mystery by Real Time Gaming is a captivating video slot that pulls players into a world full of secrets, suspense, and classic detective vibes. With its thrilling theme, clever bonus elements, and a clean visual presentation, this slot delivers an exciting experience that has made it a long-running favorite in many RTG casinos. Below is a detailed description of It’s a Mystery, including gameplay structure, symbols, features, jackpots, RTP, and why so many slot fans keep coming back.

A strong theme and the chance for solid wins have made It’s a Mystery one of the true evergreen titles in RTG casinos online. Since the game’s release in February 2011, slot fans have played this machine by the hundreds and thousands—every day. Popular features such as Scatter, Wild, and Free Spins are certainly part of the reason for its popularity, because these extras are often responsible for the kind of “brutally good” wins players hope for.

Mystery / detective theme, released in February 2011, up to 25 paylines, flexible bets from €0.01 to €125, plus random progressive jackpots.

Is It All About the Graphics?

Even though the newest slot releases today might technically outperform It’s a Mystery in terms of modern animation and graphical effects, it’s actually difficult to call the visuals here “weak” or “average.” In fact, the graphics are subtle, clean, and pleasant—especially during longer sessions.

Many modern slots throw countless animations, flashes, and effects at the player. That can look impressive for 20 spins, but after 100 rounds it often becomes exhausting. It’s a Mystery, on the other hand, can be played for hours without the feeling that annoying effects are pushing your nerves. The design stays focused and calm, which is exactly what many players appreciate about classic RTG titles.

Overall, the game feels organized and easy to understand, so even new players can quickly find their way around. At the top of the interface, the jackpot displays are always visible—meaning players can keep an eye on the potential mega prize at all times.

A major strength of the slot is its clean, non-stressful design: easy to read, comfortable for long sessions, and the jackpot amounts are always visible on screen.

Paylines and Betting

Betting in It’s a Mystery is fully flexible and can be adjusted depending on your bankroll. The slot can be played with 1 to 25 paylines, and each line can be set with a value from €0.01 up to €5. That creates a total bet range from €0.01 per spin all the way up to a massive €125 per spin.

This makes It’s a Mystery not only a classic penny slot (a slot that can be played with one cent per spin), but also a true high-roller machine. According to provider information, the average stake in this game is roughly €1.75 per round, which places it in a very approachable “everyday slot” range for most players.

• Paylines: 1–25 selectable
• Line bet: €0.01 to €5
• Total bet range: €0.01 to €125 per spin
• Average bet (provider-stated): ~€1.75 per spin

Game Mechanics and Features

It’s a Mystery includes several classic RTG features that keep the gameplay exciting and give the slot its long-term appeal. The key mechanics revolve around Wild substitution, Scatter-triggered benefits, Free Spins, and an interactive Mystery Bonus Game.

Basic Rules

The core rules are straightforward, which is part of why the game remains beginner-friendly:

• Set your stake: choose paylines (1–25) and your line bet.
• Spin: match identical symbols on active paylines to score wins.
• Trigger features: land special symbols to activate multipliers, free spins, or bonus events.

Wild Symbol

The Wild symbol is described as a detective-style symbol in the general rules section, while the symbol list highlights the green Question Mark as the Wild. Either way, the function remains the same: it acts as a joker and substitutes for most regular symbols (except Scatter) to complete winning lines and increase payout frequency.

• Wild: green Question Mark (as described)
• Function: substitutes for all regular symbols except Scatter
• Purpose: completes winning combinations and boosts consistency of line wins

Wild feature: the Question Mark acts as a joker, replacing regular symbols (except Scatter) to complete paylines and increase win frequency.

Scatter Symbol, Multipliers, and Free Spins

The slot description includes Scatter behavior in multiple places: the symbol section describes a Magnifying Glass Scatter that can multiply wins by 2x, 10x, or 200x, while the feature overview also mentions Scatter symbols triggering Free Spins when three or more appear.

In practical terms, the key takeaway is that the Scatter is one of the most important symbols in the game: it can be tied to major multipliers and it can also be linked to bonus activation such as Free Spins, depending on how the specific RTG casino version is configured.

• Scatter: Magnifying Glass (as described)
• Multiplier potential: 2x / 10x / 200x (as described)
• Free Spins: triggered by 3+ Scatter appearances (as described)
• Free Spins boost: additional Wilds and/or multipliers can appear during free spins (as described)

Big moment symbol: the Magnifying Glass Scatter can deliver extreme value through multipliers up to 200x and can also be tied to Free Spins triggers (version-dependent as described).

Bonus Feature: Mystery Bonus Game

It’s a Mystery contains an interactive bonus feature called the Mystery Bonus Game. This bonus is described as being triggered by certain bonus symbols and then places the player into a selection-style mini-game where they pick from different “secret clues” to reveal prizes.

The idea fits perfectly with the theme: instead of only spinning reels, you also get moments where you actively “investigate” and uncover rewards, making the gameplay feel more varied and story-like.

• Bonus feature: Mystery Bonus Game
• How it works: choose between secret clues to uncover rewards
• Rewards: instant prizes and potentially additional features (as described)

Interactive highlight: the Mystery Bonus Game lets you pick clues to reveal rewards—adding variety beyond standard reel spinning.

Winning Progressive Jackpots

One of the most exciting parts of It’s a Mystery is the inclusion of progressive jackpots. According to the description, these jackpots can be won at any time and on any spin, because they are triggered randomly. The stake size can influence which jackpots a player qualifies for, meaning the potential jackpot tier may depend on how much you bet.

This jackpot element is a major reason the game has remained popular for so long: every spin carries the feeling that something big could happen—without needing a specific symbol line-up.

Progressive jackpots: described as random and potentially winnable on any spin, with eligibility/tier influenced by bet size.

Paylines and Combinations

With up to 25 paylines, the slot offers plenty of ways to win. The best-paying icons are the premium “mystery” symbols—items and character-style figures tied to detective work—while the Wild and Scatter are the main drivers behind feature-based spikes in payout.

• Premium win symbols: detective tools, secret files, keys (as described)
• Wild: completes lines and increases hit rate
• Scatter: key feature trigger + multiplier power

It’s a Mystery is described as having medium volatility. That means the slot aims for a balanced experience: smaller wins appear with some regularity, while larger payouts happen occasionally—often driven by features such as Scatter multipliers, Free Spins, and the Mystery Bonus Game.

Volatility: medium — a balanced mix of steady smaller wins and occasional larger spikes through features and bonus triggers.
