Mystery Mice

Theme and Design

What do you get if you cross Stuart Little with Sherlock Holmes? Pragmatic Play believes you get Mystery Mouse. The cute character stands to the side of the reels in a very dapper suit and cap, with a magnifying glass in hand. 

The background for the base game is a quiet London street at night time, illuminated by a buzzing streetlight. For the free spins round we move inside Mystery Mouse’s office that’s lined with books and paperwork. It’s definitely taken great inspiration from Sherlock Holmes, but the fact that all of the characters are mice makes this almost unbearably cute.

RTP and Variance

Like many Pragmatic Play slots Mystery Mice has a variable RTP. The default rate is 96.49% but operators can choose to use lower rates of 95.55% or 94.48%. It’s well worth taking a moment to check what the RTP is at your chosen casino before making your bets as while the default RTP is great, the other two aren’t so good. This is combined with high volatility, so consider your bankroll and whether it can weather a dry spell!

Maximum Win

The top payout of 5,000x your stake is pretty average for an online slot these days. Would we be excited if we hit the top payout? Absolutely. But if you want to aim for bigger wins you should check out our list of Pragmatic Play's biggest paying games.

Symbols and Paytable

Mystery Mice is played on 6 reels and 6 rows and features a cluster pays system where winning combinations are formed when at least five identical symbols connect vertically or horizontally. 

The game has eight pay symbols in total, plus a wild and a scatter symbol. The low-value symbols are Q, K, and A, awarding between 0.2 and 1 times the bet for clusters of five, and between 20 and 30 times the bet for clusters of 15 or more. The premium symbols, which include a pipe, hat, police mouse, criminal mouse, and detective mouse, pay between 0.4 and 1.5 times the bet for clusters of five, and between 40 and 150 times the bet for clusters of 15 or more.

Features and Gameplay

Mystery Mice uses an interesting 'Power Wilds' mechanic to help you make more wins. There’s also a free spins to look into as well, let’s see how they all work.

Tumbles After Every Win

Whenever a win is created the tumble feature begins. The winning symbols are removed from the reels and new symbols tumble into their place. Any new wins that are created are awarded and the tumble starts again until no new wins are made. 

Power Wilds Stick On The Reels

If a poster symbol pops up then this is a wild. Every wild has a clearance level attached to it, which ranges from 1 up to 10. Each time a wild makes a win its clearance level drops by 1. The good news is that as long as a wild has a clearance number, it stays on the grid for subsequent tumbles, dropping down to fill any spaces left by winning symbols. Once a wild's number gets to zero it is removed in the next tumble.

Free Spins With Persistent Wilds

If you land 3 or more scatter symbols then the free spins round begins with 8 free spins. As well as this, each of the scatters that triggers the free spins round also pays 1x the bet. If you land 2 or more scatters in the round then you get an additional free spin.

During this round wild symbols stay in place between spins. You can also land power up symbols which add 1, 2, or 3 clearance levels to the wilds currently on the reels.
