Onlyplay’s 3×3 Mummy Coins slot offers a dual-feature punch. This medium-volatility game has a 95.05% RTP, a Coin Respin game, and a 10,000x Jackpot Game.

Mummy Coins Feature Summary
| Feature Name | Description | Trigger / How it Works |
|---|---|---|
| Wild Symbol | The Pyramid symbol substitutes for all paying symbols except the Scatter. It is also the highest-paying symbol. | Lands on any reel. 3 on a payline award 100x the bet. |
| Coin Respin Game | A hold-and-win style feature where coin symbols fill the grid. | Triggered by landing 3 Scatter symbols (the smiling Mummy). |
| Jackpot Game | A “pick-me” bonus game where players match gems to win one of five fixed jackpots. | Triggered by landing 1, 2, or 3 Coin symbols (the Pharaoh mask). |
| Jackpot Multiplier | A win multiplier applied to the jackpot won in the Jackpot Game. | 1, 2, or 3 triggering Coin symbols award a x1, x2, or x3 multiplier, respectively. |
Understanding the Mummy Coins Demo Gameplay
This game operates on a compact 3-reel, 3-row grid, but it utilizes 5 fixed paylines to calculate wins. These lines cover the three horizontal rows as well as the two main diagonals, meaning wins can form from corner to corner. All wins are calculated for three identical symbols on one of these lines.
The best way to understand its rhythm is to play the Mummy Coins demo. On Respinix, you can use the free demo game to see exactly how the two bonus features trigger and pay out without any risk.
Symbols and Payouts
The paytable is straightforward. All payouts are for landing 3-of-a-kind on a payline:
- Wild (Pyramid): 100x the bet
- Sphinx: 50x the bet
- Scarab: 20x the bet
- Vase: 10x the bet
- A, K, Q, J (Royals): 5x the bet
The Wild Symbol is the most valuable symbol in the game, paying double the next highest symbol, the Sphinx. It substitutes for all symbols mentioned above, but not the Scatter (Mummy) or the Bonus (Coin).
Legend of the Symbols: The Mummy's Hoard
| Symbol | Its Meaning in the Game |
|---|---|
| Sphinx | The highest-value standard symbol. Represents guarding the great treasures, paying 50x for a line of three. |
| Scarab | A mid-tier symbol. In ancient Egypt, it was a symbol of rebirth, and here it fittingly pays 20x. |
| Mummy (Scatter) | This cheerful-looking mummy is your key to the Coin Respin Game. It doesn't pay directly but unlocks the tomb's riches. |
| Pharaoh Coin (Bonus) | This Coin symbol is the trigger for the Jackpot Game, leading you to the pharaoh's ultimate Treasure. |
Core Game Features and Special Mechanics
The gameplay in Mummy Coins is defined by its two special symbols: the Scatter and the Coin. They do not interact but instead trigger their own unique, high-potential bonus rounds.
What Triggers the Coin Respin Game?
The Coin Respin Game is triggered by landing 3 Scatter symbols—the smiling Mummy—anywhere on the 3×3 grid in a single spin.
How Does the “Coin Game” Mechanic Work?
This feature is the game's version of a hold-and-win round. When triggered by the 3 Scatters, the game transitions to a new grid. The unique rule here is that “empty nearest cells are filled with coin symbols vertically and horizontally.” This means the coin symbols spread from the initial triggers, potentially filling the entire 9-position grid with cash values.
This “spreading” mechanic is a fantastic visual and offers a different feel from the typical ‘Hold & Spin' where you're waiting for new symbols to land. Here, the action is immediate and explosive as the coins fill the screen, after which their values are summed up and awarded.
The Jackpot Game: Your Path to the Grand Prize
The second, and arguably more potent, feature is the Jackpot Game. This is triggered by landing 1, 2, or 3 of the golden Pharaoh Coin symbols. These are separate from the Scatters.
Once triggered, you are taken to a 4×3 grid of 12 mystery stones. You click stones to reveal gems corresponding to one of the five jackpots: Mini, Minor, Major, Mega, and Grand. The first jackpot you match three gems for is the one you win.
Vlad Hvalov here. Don't confuse the two main features. The smiling Mummy (Scatter) starts the ‘Coin Respin Game' for instant cash. The golden Pharaoh Coin (Bonus) is your ticket to the ‘Jackpot Game'. They are two separate, powerful features. Focus on which one you're chasing.
How Do Multipliers Work in the Jackpot Game?
This is the most critical detail of the Jackpot Game. The number of Coin symbols that triggered the feature determines your jackpot multiplier:
- 1 Coin Symbol: x1 Multiplier on your jackpot win.
- 2 Coin Symbols: x2 Multiplier on your jackpot win.
- 3 Coin Symbols: x3 Multiplier on your jackpot win.
This multiplier is applied after you win the jackpot. Winning the 1,000x Mega Jackpot is great. Winning it from a 3-Coin trigger turns it into a 3,000x win. This makes landing 3 Coins the most desirable event in the entire game.
Mathematical Model: Volatility, RTP, and Win Potential
Mummy Coins is built on a mathematical model that creates a specific, tension-filled experience.
What is the Mummy Coins RTP?
The Return to Player (RTP) for Mummy Coins is 95.05%. This theoretical metric is slightly below the 96% industry average, suggesting the house edge is a bit higher.
Understanding Mummy Coins Volatility and Hit Rate
This slot has Medium Volatility. This means it's designed to provide a balance between the frequency of wins and the size of those wins. However, published data indicates a very low Hit Frequency of 7.25%.
This combination is unusual and defines the game. It means you will not get small, frequent line wins. The base game is quiet. The entire mathematical weight and excitement are loaded into the two bonus features. This slot is not for players who need constant small rewards. It's for players who are willing to wait for one of the two big bonus events to trigger.
Jackpot Values and Max Win Explained
The jackpots are fixed multipliers of your total bet, which is a key difference from progressive jackpots. The Max Win is 10,000x your bet, which is achieved by winning the Grand Jackpot.
- Mini: 5x bet
- Minor: 20x bet
- Major: 100x bet
- Mega: 1,000x bet
- Grand: 10,000x bet
Achieving the 10,000x Grand Jackpot is the game's ultimate prize. Remember, if you trigger this with 3 coins, the x3 multiplier would apply, but the 10,000x is the capped maximum win.
A tip from me, Vlad Hvalov: That 10,000x Grand Jackpot is the real prize. The key isn't just entering the Jackpot Game; it's entering it with 3 Coin symbols. That x3 multiplier is what turns a 1,000x Mega win into a 3,000x win. The number of triggering coins is critical.
One more thing on those Jackpots. It's tempting to chase them, I get it. In the demo, try setting a ‘jackpot hunt' limit. For example, ‘I'll play 100 spins only to see if I can trigger the Jackpot Game.' This teaches you patience and bankroll management for this specific goal, without getting lost in the spin.
Audiovisuals and Thematic Immersion
Visually, Mummy Coins is clean and bright. It's set against a backdrop of pyramids in a golden Desert, with a small oasis. The symbols are large, colorful, and easy to read. This isn't a dark and gritty tomb-raiding game like Book of Dead. The Onlyplay design gives it a more playful, modern, and accessible feel. The animations for the Coin Game (with spreading coins) and the Jackpot Game are smooth and build excitement effectively. It fits well within the broad category of Gold and Mythology themed slots, which you can browse on our full themes page.
Special Insights into Mummy Coins
Streamer's Verdict: Is Mummy Coins Watchable?
Here's the breakdown for content creators:
- Visual Appeal: It's bright and clear. The grid is simple, so viewers can easily follow the action. The “Coin Game” with spreading symbols is a great visual payoff.
- Hype Potential: High. The entire game is built for “pop-off” moments. The Jackpot Game, in particular, is high-drama. The moment you land 3 Coin symbols (for the x3 multiplier), the chat will light up. The 10,000x max win is a massive, stream-worthy prize.
- Dynamics: This is the only drawback. The base game can be slow due to the low hit rate. A streamer will need to be entertaining during the quiet spins while building anticipation for one of the two features. It's not a rapid-fire game like Wanted Dead or a Wild.
Final Verdict: Good for streaming, but best saved for high-energy sessions where you're actively “hunting” the features.
Secrets of the Sarcophagus
- It's a 5-Line Game: Don't be fooled by the 3×3 grid. The game pays on two diagonals and a ‘V' shape, not just the three horizontal lines.
- Wild is King: The Wild symbol (Pyramid) isn't just a substitute; at 100x, it's the single highest-paying symbol in the game, paying double the Sphinx.
- The x3 Multiplier is Everything: The difference between a 1-Coin and 3-Coin trigger for the Jackpot Game is massive. That x3 multiplier is the key to the game's biggest non-Grand Jackpot wins.

Final Thoughts on Mummy Coins
Mummy Coins is a strong, focused title from Onlyplay. It knows exactly what it wants to be. It avoids the complexity of modern multi-way slots and instead doubles down on two high-potential, easy-to-understand bonus features. This is its signature.
The low hit rate of the base game is a deliberate choice, designed to make the triggers for the Coin Game and Jackpot Game feel even more explosive. It’s not a game for a casual, low-intensity session. It’s a game for a player who wants a clear-cut hunt for a massive 10,000x prize. I respect its design. It's a solid and entertaining slot, especially for a demo session where you can really push to see those big features land.
