Pots of Power: Mummy's Treasure Slot Review – Demo, RTP & Features

Ancient Egypt has no shortage of hidden riches, but finding them usually involves disturbing something that would rather be left alone.

Pots of Power: Mummy’s Treasure, developed by AvatarUX, takes players into a mysterious Egyptian tomb filled with golden artefacts, scarabs and a rather cheerful mummy who accompanies the action.

The game is the second instalment in the Pots of Power series, following Pots of Power Zeus. While the original explored Greek mythology, Mummy’s Treasure exchanges Mount Olympus for the burial chambers of the pharaohs.

The setting is familiar territory for online slots, although the colourful cartoon presentation gives the ancient tomb a lighter atmosphere than its surroundings might suggest.

Played on a 5×3 grid with 25 fixed paylines, Pots of Power: Mummy’s Treasure keeps its regular gameplay relatively simple. The main attraction is a randomly triggered Hold & Win bonus, where a three-part Bonus Wheel determines the size of the playing area, the number of starting spins and how many Power Frames enter the feature.

These moving Power Frames provide the game’s most interesting mechanic. They travel across the bonus grid, increase the values of Coins and combine their own values when connected, creating opportunities for larger accumulated prizes.

With medium volatility, a maximum win of 10,000x the stake and a highest stated RTP of 96.10%, Mummy’s Treasure offers a substantial payout ceiling without adopting the highest volatility classification.

Bets range from €0.10 to €500, while an Ante Bet and two bonus purchase options provide alternative ways to access the main feature.

Game Features

Pots of Power: Mummy’s Treasure revolves around collecting Bonus symbols and unlocking a configurable Hold & Win round. Although the base game follows a traditional payline format, the bonus introduces moving Power Frames, different grid sizes and additional multipliers for completely filling the playing area.

Base Game and Bonus Collection

The main game uses five reels, three rows and 25 fixed paylines. Its Egyptian-inspired symbols include traditional playing card ranks alongside a collection of themed objects such as scarabs, pyramids, scrolls and ceremonial artefacts.

A Pharaoh’s pot positioned above the reels plays an important role in activating the main feature. Whenever special Bonus symbols appear, they are collected into the pot. Each collected symbol provides a chance of randomly triggering the Hold & Win bonus.

Unlike slots that require a fixed number of Scatters to activate their features, Mummy’s Treasure uses this collection-based system to determine when the bonus begins. This creates a degree of anticipation during ordinary spins, although most of the game’s more elaborate mechanics are reserved for the bonus round itself.

Bonus Wheel

When Hold & Win activates, a three-part Bonus Wheel determines the starting configuration of the feature.

Each section of the wheel controls a different element:

• Grid Size: 5×4, 5×5 or 5×6
• Starting Spins: 3, 4 or 5
• Power Frames: 2, 3 or 4

With three possible outcomes for each category, the wheel can generate 27 different starting configurations. The resulting combination has a considerable influence on the feature.

A larger grid provides more positions for Coins and Power Frames, while additional starting spins create more opportunities to develop the accumulated prizes.

The number of Power Frames also matters, as these symbols are responsible for increasing Coin values and interacting with one another. Once the wheel has selected the configuration, the playing area and initial setup remain fixed for the duration of the bonus.

Hold & Win Bonus

The Hold & Win feature moves the action away from conventional payline combinations and focuses on accumulating Coin values across the expanded playing area.

Depending on the Bonus Wheel result, the grid contains between 20 and 30 positions. Coins carry prize values that contribute to the total accumulated reward, while Power Frames move around the board and interact with those Coins.

The feature’s starting spin count is determined by the Bonus Wheel, making each activation potentially different from the last.

The central objective is to build the value of the collected prizes, with additional rewards available if every position on the grid becomes occupied.

Power Frames

Power Frames are the defining mechanic of Pots of Power: Mummy’s Treasure. Each Power Frame begins with its own value and can move around the grid between spins. Whenever a Power Frame lands on a position occupied by a Coin, the Frame’s value is added to that Coin.

This allows existing prizes to grow through repeated interactions rather than relying exclusively on new high-value Coins appearing.

The moving Frames introduce an element of progression, as their positions can influence which Coins receive additional value during the feature.

The number of Power Frames available is determined before the bonus begins, with the Bonus Wheel awarding two, three or four Frames.

Connected Power Frames

Power Frames become even more valuable when they connect with one another. If two or more Power Frames become adjacent horizontally or vertically, their values are combined.

The resulting total is then applied to every Power Frame involved in the connection. For example, if a Frame worth 5x connects with another worth 10x, their combined value becomes 15x, which is applied to both connected Frames. This allows multiple Power Frames to increase their values simultaneously. As these enhanced Frames continue moving around the grid, they can potentially transfer their larger values to Coins.

The mechanic adds an interactive element to the Hold & Win format, since the positioning and connection of Power Frames can become just as important as the Coins themselves.

Full Grid Multipliers

Completely filling the Hold & Win grid awards an additional multiplier applied to the total accumulated prize. The multiplier depends on the playing area’s size, as determined by the Bonus Wheel.

The largest grid offers the strongest full-board multiplier, although filling all 30 positions also requires more symbols than completing the smaller configurations. These rewards give players an additional objective beyond simply increasing individual Coin values.

A fully occupied board can substantially improve the final payout, particularly when Power Frames have already increased several Coin prizes.

Ante Bet

Pots of Power: Mummy’s Treasure includes an optional Ante Bet for players who want to increase their chances of triggering Hold & Win through regular gameplay.

Activating the Ante Bet raises the normal stake to 1.5x its standard value. In exchange, the probability of triggering the bonus is doubled. This option does not guarantee a bonus activation, but it provides an alternative to waiting for the standard collection mechanic or purchasing the feature directly.

Bonus Buy

Two feature purchase options are available where permitted.

The Standard Bonus Buy preserves the uncertainty of the Bonus Wheel, meaning players can receive any of the 27 possible configurations.

Bonus Max removes that uncertainty by providing the strongest available starting setup. With 30 positions, five starting spins and four Power Frames, Bonus Max offers more room and opportunities to develop the feature’s prize values. However, the 500x purchase price represents a substantial investment, and even the strongest starting configuration does not guarantee a profitable result.

Bonus purchases may be unavailable in certain markets or at casinos that restrict feature-buy mechanics.
