Mystery Mice gives sticky wilds a finite level rather than a permanent fixed value. Power Wilds arrive from level one to ten, lose one level when used in a winning tumble and can gain one to three levels from upgrade symbols. Free spins preserve them between results. The saved 6×6 version lists 96.49% RTP and a 5,000x maximum.

Power Wilds spend a level when useful
The board settles through cluster pays on six reels and six rows. A Power Wild can land at any level from one to ten and remains sticky through winning tumbles. Each time it contributes, it loses one level, connecting its lifespan to actual use rather than simply to the number of cascades.
Upgrade symbols add one to three levels, counteracting some of that consumption. The provider reference records 96.49% RTP but no volatility, wager limits or minimum cluster size. Its 5,000x maximum is the whole-game ceiling; Power Wild levels represent durability or strength state, not direct 10x prize values.
Free spins carry the board state forward
Three or more spyglass scatters award between ten and eighteen free spins. During that round, Power Wilds persist between separate spins as well as through winning tumbles. This longer lifespan lets a developed position remain available until its levels are consumed or the feature ends.
Additional scatters add spins. Extra time may expose existing Power Wilds to more wins and more upgrade symbols, but it can also consume their remaining levels. The relationship is therefore balanced: extensions increase opportunities to use and improve positions without guaranteeing that a level-ten wild survives to the final result.
Useful wilds can be depleted
The limitation is resource loss through success. A wild that repeatedly contributes also moves closer to disappearing, and an isolated high-level position may see no matching cluster. The saved record does not map scatter counts to the 10–18 allocation or specify how many spins each later scatter adds.
Its strength is a transparent lifecycle. Landing level, consumption, upgrade and cross-spin persistence are all visible states with defined causes. The mechanic rewards attention to board location and remaining levels, giving the mouse-and-spyglass presentation a strategic identity without relying on an unsupported fantasy category.
Mystery Mice is a 6×6 cluster slot where Power Wilds behave like limited resources. They land at levels 1–10, stay through winning tumbles, lose one level when used and can gain 1–3 from upgrades. Three or more spyglasses provide 10–18 free spins, where those positions persist across attempts and later scatters extend the round. The design’s strength is a clear lifecycle that connects success with depletion; its risk is that valuable positions may be consumed or bypassed. The saved 96.49% RTP and 5,000x maximum frame the reference version, while volatility and exact scatter mappings remain unconfirmed and should not be inferred.
Strengths
Power Wilds have a visible lifecycle: they land with a level, persist through winning tumbles, lose one level when used and can regain levels through upgrades. That makes both board position and remaining strength meaningful during the 6×6 cluster game and its free-spin feature.
Weaknesses
The useful wild can be depleted by the very wins it helps create, while a high-level wild in an isolated position may contribute little. The source does not map scatter counts to the 10–18-spin allocation or state the exact extension for later scatters. A displayed level is a resource state, not a direct multiplier or guaranteed prize value.
Our Editor’s View
Mystery Mice makes a wild symbol feel like a limited resource rather than a permanent upgrade. I like how a useful position can persist across tumbles and bonus spins, yet successful participation also consumes a level; the player can see both progress and depletion. The 1–3-level upgrade offers a counterweight, not a promise that a strong position survives indefinitely. I would watch location and remaining level together, while checking the active paytable for the missing scatter allocation and cluster details.
