Mystery Mice (Pragmatic Play) – Review & Demo Play

The Mystery Mice Slot Game

Mystery Mice drops you into a dusky street scene with a grinning mouse detective beside a 6x6 grid. It’s a cluster pays setup, so wins land when 5+ matching symbols connect horizontally or vertically. Tumbles remove wins and drop fresh symbols for chained hits. The base game ticks along, but the tone shifts once the bonus lands and the office scene takes over. Bets range from €0.20 to €240, and the flow suits mobile or desktop without fuss.

Symbols and Payouts in Mystery Mice

There are eight regulars. Low pays are Q, K, and A, returning 0.2x to 20x, 0.25x to 25x, and 0.3x to 30x for clusters from 5 up to 15+. The Smoking Pipe and Cap step things up at 0.4x to 40x and 0.45x to 50x. Values scale with bet size, so the paytable tracks your stake in real time. Cluster size matters more than position, as there are no lines in play.

Premiums carry the case. The Police Officer pays 0.5x to 60x, the Suspect 0.75x to 100x, and the Detective tops the sheet at 1x to 150x for 15+. The Poster is a Power Wild that substitutes all pay symbols, and the Magnifying Lens is the scatter. Three or more scatters trigger the free spins. It’s a clean set of symbols that fits the theme and makes cluster counting straightforward during tumbles.

Mystery Mice Slot Bonus Features

Tumble removes all winning symbols, then drops remaining icons to the bottom while new ones fall from above. This repeats until no new cluster forms. The mechanic is simple and sets the rhythm for streaky rounds, especially when wilds chain several wins together. In my sessions, base game tumbles gave steady extras, but the heavy lifting came when wilds lined up during the feature.

Power Wilds land with a clearance level from 1 to 10. Each time a wild is part of a win, that number drops by one. If it’s still above 1, the wild won’t explode on the tumble. It slides to the lowest position and waits for the next connection. When a wild with clearance 1 helps a win, it’s removed. This behaviour sets up stacks near the bottom during hot runs.

Three or more scatters award eight free spins, and each triggering scatter pays 1x the stake upfront. In free spins, Power Wilds persist between spins, which is where the game opens up. Power Up symbols can land and add +1, +2, or +3 clearance to every wild in view. Land 2+ scatters to retrigger, adding spins equal to scatter count plus one. There’s a bonus buy at 100x bet where permitted.

How to Win at Mystery Mice Slot

It’s a 6x6 cluster engine, so aim for boards with space for cascades and keep stakes sensible through dry spells. I favour steady spins in the base and let the Power Wilds do the work when they drop early in a round. If you have access to fast play, Turbo helps you read the tumble flow. Check you’re on the top RTP setting before you start, and treat the bonus as the main route to sizeable outcomes.

Mystery Mice Slot RTP & Volatility

Default RTP sits at 96.49%, though some operators use 95.55% or 94.48%. That range matters over time, so I always check the info panel in real money mode. Volatility is high, marked 5/5, and it plays that way. The win cap is 5,000x bet. Free spins arrive off 3+ scatters and can stretch when retriggers and Power Ups land in tandem. Expect patches of quiet followed by bursts when the grid aligns.

The maths shines in the feature. Sticky Power Wilds between spins, plus clearance top-ups, let the lower rows fill with posters that keep combing clusters. The cap has a hit rate in the millions of spins, so treat anything four figures as a strong result. Bet range runs from €0.20 to €240, which suits low stakes testing and higher stakes chases, but the variance punishes overextension quickly.

Mystery Mice: Slot Verdict

Base play is tidy, with occasional Power Wild links, but it’s the bonus that sold it for me. Holding wilds between spins and dropping them to the bottom creates chunky blocks that churn through clusters. Add a timely Power Up and the grid can go on a tear. The adjustable RTP is the main caveat. Outside of that, it’s a sharp cluster slot with a fair 5,000x cap and a theme that stays entertaining across sessions.
