Mystery Mice is a high-volatility 6×6 cluster slot from Pragmatic Play where Power Wilds enter at levels from 1 to 10, remain through tumbles and lose one level after joining wins.
Our review examines whether level-based Wild persistence creates controllable grid progress or remains dependent on random placement.

How Power Wild levels work
The detective grid pays when five identical symbols connect horizontally or vertically across the 6×6 board. Winning icons disappear, replacements tumble into position, and play continues on the same stake while another group forms.
Power Wilds can land with levels from 1 to 10 and substitute within clusters. Each time one contributes to a win, its level decreases by one, allowing it to remain through later tumbles until the counter reaches one and the Wild explodes.
Spyglass Scatters start free spins when three or more land. Power Wilds remain sticky between bonus spins, Power Up symbols add one to three levels, and two further Scatters add another spin.
How level decay affects clusters
- Clusters: Five connected symbols begin each tumble sequence.
- Power Wild: Random starting levels range from one to ten.
- Level decay: Each qualifying win removes one Wild level.
- Power Up: Special symbols add one to three levels.
- Sticky bonus: Power Wilds remain between awarded free spins.
- Retrigger: Two bonus Scatters add one extra spin.
Wild lifespan and payout limits
Base-game value depends on whether a Power Wild lands near symbols that can form repeated clusters. A high starting level increases its possible lifespan, but placement still determines whether later tumbles use that remaining counter.
Free spins retain Power Wilds between spins and can restore levels through Power Ups. The persistent state creates more opportunities than base play, while unused Wilds can still occupy positions without joining a paid cluster.
Reaching the listed x5,000 cap depends on several levelled Wilds supporting valuable connected groups across an extended feature. Level increases alone do not create payouts, and counters can expire before premium symbols settle nearby.
Player fit and limitations
- May suit: Players who track visible Wild lifespan counters.
- May suit: Players preferring persistent cluster modifiers in bonuses.
- May not: Players wanting Wild value fixed without level decay.
- May not: Players who dislike position-dependent feature progress.
Power Wild counters decrease whenever they contribute to wins.
