Introduction to The Lost Book of Mummy’s Curse
The Lost Book of Mummy’s Curse is a casino slot from Trusty Gaming with an attempt to appeal with familiar gameplay and a cartoonish vibe. Trusty Gaming is a newcomer in the slot market, using Hacksaw Gaming’s platform. Here, they’ve added another edition to the well-known “Book of” series, known for its Expanding Symbol mechanic. The studio has previously released Book of Whispers, and this time, they’ve included Big Symbols and decent visuals. However, it feels like we’ve seen it all before, and combined with weak payout potential, it didn’t meet our expectations. Let’s continue with the stats.

Theme, Gameplay, & Payouts
The Lost Book of Mummy’s Curse is a video slot by Trusy Gaming that features 5 reels, 3 rows, and 9 paylines. You can select bet sizes ranging from 0.1 to 300, with a default RTP of 96.32%, which is regarded as slightly above industry average. However, operators can choose the lower option of 94.38% as well. This game has medium volatility, a hit frequency of 32.1%, and offers potential wins of up to 3,000X your bet.
The game’s design is cartoonish, with an Ancient Egyptian theme featuring cute cats and scary-looking mummies. The 5x3 game grid is set inside a temple, and if you want to boost the gaming experience for a cost, activate the Feature Buy button on the left side. All other buttons, including the Spin and Bet Size, can be found below the reels. You can play The Lost Book of Mummy’s Curse on all mobile devices, desktops, and notepads. You create a winning combination by landing 3 or more of the same symbol types on adjacent reels starting at the leftmost reel.
The lower-paying symbols are golden staff, pyramid, scarab, crook & flail, and Ankh. Landing 5 of the same symbol type pays between 5X and 10X. The higher-paying symbols are a baby Cleopatra, a bird, a crocodile, and a cat. Landing 5 of the same symbol type pays between 75X and 200X. Landing 2 of the higher-paying symbol pays between 1X and 1.5X the bet.
The game’s Wild Symbol has the design of a mummy, and creating a win with 5 Wild Symbols pays 1,000X the bet. The Scatter Symbol is a book, and landing 3 or more will trigger the Bonus Game. Depending on whether you land 3, 4, or 5 Scatter Symbols award a direct payout of 5X, 10X, or 15X the bet, respectively. Let’s find out what kind of features this game has to offer.
Special Features & Slot Mechanics

The max win is 3,000X the bet.
What features are available in the slot of The Lost Book of Mummy’s Curse?
The features of this slot game are Wild Symbol, Expanding Feature, Free Spins, and Feature Buy.

Wild Symbol
The Wild Symbol substitutes all symbols except the Scatter and Special Expanding Symbols and helps you create winning combinations. If 3 Wild Symbols land on reels 2, 3, and 4 simultaneously, these Wild Symbols transform into a 3x3 Wild Symbol.
Creating a win with 5 Wild Symbols pays 1,000X the bet.
Expanding Feature
On any Base Game spin, a random regular paying symbol type can become a Special Expanding Symbol for that spin. This expanded symbol covers the entire reel if it creates a win.
Free Spins
This feature can be triggered by landing 3 or more Scatter Symbols, awarding 12 Free Spins. Depending on whether you land 3, 4, or 5 Scatter Symbols award a direct payout of 5X, 10X, or 15X the bet, respectively. You can retrigger the feature by landing 3 Scatter Symbols, granting 6+ additional Free Spins.
Before the feature starts, a random paying symbol type is selected as the Expanded Symbol. If the selected symbol type creates a win during the feature, it will expand and cover the entire reel. However, the chosen symbols don’t need to land on reels next to each other. As long as enough of them appear to form a winning combination, they will expand.
Feature Buy
If you want to advance directly to the Bonus Game for a cost, you can use the Feature Buy option:
100X = Activates the Free Spins with an RTP of 96.35%.
Final Thoughts on The Lost Book of Mummy’s Curse
The Lost Book of Mummy’s Curse invites us to a temple in Ancient Egypt, among cute animals and familiar gameplay. Visually, it has a modern vibe and a pleasant soundtrack, making it easy to spin the reels at first.
As the Introduction mentions, it follows the familiar “Book of “ mechanic, popularized by hits like Book of Dead by Play’n GO, released in 2016. So what makes this game stand out? Well, not much to be honest. The studio provides a classic take on the familiar mechanic, with added Big Symbols that can grow to 3x3. Otherwise, it’s business as usual, which can appeal to fans of the series who want a modern look. But in terms of innovation and gameplay, we expected a more unique gaming experience.
Overall, with decent visuals and a fun soundtrack, it might attract fans of the “Book of” series, but it will have a tough time sustaining long-term interest due to repetitive, too-familiar gameplay.
The Lost Book of Mummy’s Curse is a slot with familiar gameplay and decent visuals, but it fails to create a memorable experience.
