Mystery Mice Slot Overview

Mystery Mice is a slot from Pragmatic Play. Detective theme, cute mice – yeah, yeah. Sherlock Holmes with rodents. Big deal, right? Except this one’s packing high volatility and a 5000x max win on a 6×6 grid with cluster pays. Forget the Cumberbatch fluff, let’s see if these mice can actually find some wins.

Mouse detective standing to the right of the reels — Base Game

Mystery Mice is a video slot. Pragmatic Play. 6 reels, 6 rows. Cluster pays – ditch the paylines. 5+ matching symbols anywhere is a win. Bets from 0.20 to 240. RTP? They give you choices. Base is 96.49%, but casinos can screw you with 95.55% or 94.48%. Free spins hit about 1 in 251 spins. Base game hit frequency? 32%. High volatility. 5000x max win. Don’t hold your breath though – max win hits once in almost 8 million spins. 1000x+ wins? Closer to 1 in 109k spins.

Features? Yeah, it’s got some. Tumbles, Wilds, Free Spins, Feature Buy. Standard stuff, let’s dig in.

Mystery Mice Slot Information

Detective theme. Mice. Duh. Reels in the middle, night city backdrop. Bonus buy button to the left – tempting, right? Spin and bet controls at the bottom. Mobile, desktop, tablet – works everywhere. Clusters of 5+ symbols trigger tumbles. You know the drill.

Low pays: Q, K, A. Hit 15 of those, you’re looking at 20x to 30x your bet. High pays: pipe, hat, cop mouse, crook mouse, detective mouse. 15 premiums? 40x to 150x bet. Not bad, but not life-changing.

Wild symbol is a document with a “W”. Got a “Clearance Level” 1 to 10. More on that later. Scatter is a magnifying glass with “Scatter” on it. 3+ of those triggers free spins. Let’s see what these features actually do.

Mystery Mice Slot Features

What’s the max win on Mystery Mice?

5000x your stake. Good luck hitting it.

What features are in Mystery Mice?

Tumbles, Wilds, Free Spins, and Bonus Buy. Keep up.

Free Spins

Tumble

Winning cluster? Symbols vanish. New symbols drop in. More wins? Tumbles keep going. Until no more wins. Basic cascading reels stuff.

Wild Symbol

Wild substitutes for everything but the Scatter. Helps make wins. No brainer.

Wilds land with a Clearance Level from 1 to 10. Each win a Wild’s part of, the level drops by 1. Level stays above 1? Wild sticks around, tumbles down, doesn’t disappear. Level hits 1 and it’s part of a win? Poof, gone. Wild not in a win? Vanishes instantly. Tricky little bastards.

Free Spins

3+ Scatters anywhere triggers 8 free spins. Each Scatter that triggers it pays 1x bet straight up. Re-trigger? 2+ Scatters gives you more spins – 1 extra spin per Scatter past the first two. So, 3 Scatters on re-trigger = 4 extra spins. Got it?

Free spins? Wilds stick for the whole feature. Upgrade symbol shows up. Each time it does, it boosts all Wilds on screen by 1, 2, or 3 Clearance Levels. Keeps those Wilds hanging around longer.

Feature Buy

Bonus Buy

Want free spins now? Hit the Bonus Buy. 100x your bet. RTP stays at 96.49%. Your call if it’s worth it.

F.A.Q.

What is Mystery Mice slot about?

Mystery Mice is a detective-themed online slot game developed by Pragmatic Play. It features a 6x6 grid and uses a cluster pays system instead of traditional paylines, meaning wins are formed by landing five or more matching symbols in a cluster anywhere on the reels. The game has a charming cartoonish style with mice characters acting as detectives and criminals, set against a backdrop of a nighttime city. Despite its cute appearance, Mystery Mice is a high volatility slot, offering a maximum win of 5000 times your stake. The game includes features like tumbles, wild symbols with clearance levels, free spins with sticky wilds and upgrade symbols, and a bonus buy option for instant access to free spins. It’s designed to be playable across various devices including desktops, tablets, and mobile phones.

What is the Return to Player (RTP) of Mystery Mice and are there different versions?

The base Return to Player (RTP) for Mystery Mice is set at 96.49%. However, it's important to be aware that Pragmatic Play offers flexible RTP settings, which means casinos can choose to operate the game at lower RTP percentages. You might encounter Mystery Mice with RTPs of 95.55% or even 94.48%. These lower RTP versions will decrease your expected returns over time. Therefore, it's always recommended to check the specific RTP of Mystery Mice at the online casino you are playing at, as it can significantly affect your gaming experience and potential winnings in the long run. Look for this information in the game details or casino information sections.

How do Wild symbols work in Mystery Mice and what is a Clearance Level?

In Mystery Mice, the Wild symbol is represented by a document marked with a "W". Wild symbols serve their typical function of substituting for any other symbol except for the Scatter, helping you to complete winning clusters. What makes the Wilds in Mystery Mice unique is their "Clearance Level," which ranges from 1 to 10. When a Wild symbol is part of a winning cluster, its Clearance Level decreases by 1. If the Clearance Level remains above 1 after a win, the Wild symbol will remain on the reels and tumble down with the new symbols, increasing your chances of forming more wins. However, if a Wild's Clearance Level reaches 1 and it's involved in a win, it disappears after the tumble. If a Wild is on the grid but not part of a winning cluster in a tumble sequence, it will vanish immediately.

How are Free Spins triggered in Mystery Mice and what happens during them?

Free Spins in Mystery Mice are triggered when you land 3 or more Scatter symbols anywhere on the 6x6 grid during the base game. The Scatter symbol is represented by a magnifying glass with the word "Scatter" on it. Landing 3 or more Scatters not only triggers 8 free spins but also awards you an instant payout of 1x your total bet for each Scatter that triggered the feature. During the Free Spins round, Wild symbols become sticky and remain on the reels for the entire duration of the feature. Additionally, an "Upgrade" symbol can appear during free spins. Each time an Upgrade symbol lands, it increases the Clearance Level of all Wild symbols currently on the screen by 1, 2, or 3 levels. This effectively prolongs the presence of Wilds on the reels, potentially leading to more substantial and prolonged winning combinations throughout the free spins bonus round.

Is there a Bonus Buy feature in Mystery Mice and is it worth it?

Yes, Mystery Mice offers a Bonus Buy feature, allowing players to instantly purchase access to the Free Spins bonus round. Activating the Bonus Buy will cost you 100 times your current total bet. By using the Bonus Buy, you will immediately trigger the Free Spins feature instead of waiting for 3 or more Scatter symbols to land naturally in the base game. Whether it is "worth it" is subjective and depends on your playing style and risk tolerance. The game information states that the RTP remains at 96.49% even when using the Bonus Buy feature, which is the same as the base game RTP. While it provides immediate access to the potentially more rewarding free spins, it comes at a significant upfront cost. Consider your budget and playing preferences before deciding to utilize the Bonus Buy option.

What is the volatility of Mystery Mice and how often can I expect to hit big wins?

Mystery Mice is classified as a high volatility slot game. This means that wins may not occur very frequently compared to low or medium volatility slots, but when they do occur, they have the potential to be significantly larger. While the maximum win is stated as 5000 times your stake, the probability of hitting this maximum win is extremely low, occurring approximately once in almost 8 million spins. Similarly, achieving wins of 1000 times your stake or greater is also relatively rare, estimated to happen around once in every 109,000 spins. Therefore, while Mystery Mice offers the excitement of potentially large payouts, players should be prepared for periods of smaller wins or even losses, and manage their bankroll accordingly. High volatility games are best suited for players who are comfortable with higher risk in pursuit of larger rewards, rather than frequent smaller wins.
