Double Cash Mummy Slot Review
Thomas “Mummy” Pettigrew (his actual nickname) made a living by hosting public un-bandaging of mummies in 19th-century London for wealthy patrons who paid money to have him unwrap an Egyptian corpse in their presence while they drank wine and clapped. 🍷
The fact that people thought it was a good way to spend a Saturday night, and what's even crazier about this whole thing is that apparently no one ever questioned why or how he came up with this idea. 🤔
This is Double Cash Mummy slot from Iron Dog. 🧟
Gameplay
Using warm colors and a hieroglyph-covered wall as a backdrop seems like a good fit. At the top of the reels are two guardian mummies: a chubby character on the left and a skinnier, more conventional mummy on the right. It's a strange pairing, but highly entertaining.
The game runs on a 6-reel, 4-row grid with 4,096 ways to win. Low-paying symbols are the card royals (9, 10, J, Q, K, A), all paying 0.20x to 0.80x for 3 to 6-of-a-kind.
Mid-range symbols include an Eye of Horus (up to 1.20x for 6), an Ankh (up to 1.50x), Horus (up to 1.80x), and a Scarab (up to 2.00x). The Pharaoh is the top base-game symbol and pays from as few as two matching symbols, topping out at 5x for 6-of-a-kind.
The Wild can appear on reels 2 through 6, and substitutes for all non-special symbols.
The three Jackpots (25x Mini, 250x Minor, and 2,500x Major) are displayed across the top.
The stats are: 95.16% RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.
RTP needs to be considered in conjunction with a game’s volatility rate., high volatility, 10,000x max multiplier, and a $250,000 max win. Fiat currency only (no JPY).
Features
SPECIAL COLLECTOR SYMBOL
The Treasure Chest is the Special Collector symbol and lands exclusively on reels 1 and 6 (once per reel each). When it does, it immediately sweeps the grid and collects the values of all Cash Symbols on the reels:
- Cash Coins - Values ranging from 0.5x to 20x
- Jackpot Coins - Mini (25x), Minor (250x), and Major (2,500x)
Note that Collector Symbols will not collect from each other.
BONUS COLLECT FEATURE
Landing 3, 4, 5, or 6 Scatters triggers the Bonus Collect feature and 2, 3, 5, or 8 re-spins, respectively. During the feature, Win Ways are disabled, and you’re guaranteed to land one Collector Symbol on every single spin.

BUY BONUS
Clicking the Buy Bonus in the top-right corner, gives you the following options:
- 3 Scatters (50x) - Triggers the Bonus round with 2 re-spins
- Random Number of Scatters (75x) - Get anywhere from 3 to 6 Scatters (up to 8 re-spins)
Performance
Everything was clean from start to finish. No issues to report.
Max Win
Bets run from $0.20 to $25. The $250,000 max win requires the 10,000x max multiplier on a $25 bet.
Conclusion
The Collector sweeping a grid full of high-value Cash Symbols is the most important part of the game. In the base game that happens occasionally and somewhat randomly. In the Bonus Game, it happens on every single spin, which feels like a nice bonus.
More re-spins during the Bonus Game give the grid more time to load up with high-value Cash Symbols before each sweep, so a 6-Scatter trigger at 8 re-spins genuinely plays like a different feature compared to a minimum 3-Scatter entry at 2.
The 50x buy is the straightforward call, you know exactly what you're getting. The 75x option is a coin flip on Scatter count, which is great, but there's always a chance you're paying 25x more for the same 2 re-spins.
Patient players are better off keeping bets sensible and letting Scatters land naturally. Chasing 10,000x means you need a long run with Major Jackpot Coins showing up across multiple Collector sweeps.
The 75x buy at least gives you the re-spin runway to make that a realistic conversation rather than a pipe dream.
