For us, Double Ruby is an Everi at its most stripped-back and deliberate. This is a 3-reel, 9-line real-money slot built around 1 symbol that actually matters: the Double Ruby logo, which can substitute, multiply, and carry the table’s standout prize on line 1 when the reels line up properly.

Game Overview
We’d call Double Ruby a classic Everi slot with 1 useful mechanical twist and enough value in that twist to carry the whole game. The layout is simple: 3 reels, 3 rows, and 9 fixed paylines. Wins come from BAR combinations, 7 combinations, or the Double Ruby logo itself. What changes the feel is the logo’s double role. It is the game’s top symbol, but it also substitutes for BARs and 7s and multiplies qualifying line wins to 2x with 1 logo or 4x with 2. Everi lists volatility at 3 (medium), which fits the structure: regular line action, no side systems, and 1 headline payout tied to payline 1. There are no free spins, no bonus round, no ante bet, and no bonus buy.
Game Features & Mechanics
-
Multiplier Wild
The Double Ruby logo substitutes for BARs and 7s in winning combinations. With 1 logo, the line pays 2x. With 2 logos, it pays 4x.
-
Top-Line Hit
The standout result is reserved for the centre row. Land 3 Double Ruby symbols on payline 1 and the game delivers its highest listed award.
-
Any BAR Rule
The lower symbol family is less rigid than it looks. Any 3 BAR symbols form a paying line, even when the BAR types are mixed.
-
Any Seven Rule
The 7 side uses the same logic. Any 3 sevens pay, while matching silver, gold, or ruby sets increase the value of the line further.
Technical Specifications
-
Volatility Level
Everi rates Double Ruby at volatility 3 (medium). That points to a steadier 3-reel session than most modern feature slots, with the sharpest spike tied to line 1.
-
RTP Explained
There is no official RTP information provided by the game developer. Across online casinos, it typically ranges between 93% and 96%.
-
Bet Range
This game runs on a $0.90 to $450 stake range, with coin values from $0.10 to $10 and bet multipliers going up to 5.
Paytable & Symbol Values
All wins in Double Ruby are shown in credits, so the actual return depends on both the denomination and the bet multiplier. At the lowest denomination of $0.10 with a 1x multiplier, any 3 BAR symbols pay 5 credits, which equals $0.50. A full line of single BARs pays 10 credits ($1), while 3 Double BARs return 20 credits ($2). The 7 side starts noticeably higher: any 3 sevens pay 30 credits ($3), 3 silver sevens pay 60 credits ($6), 3 gold sevens pay 100 credits ($10), and 3 ruby triple sevens pay 200 credits ($20). The top line win is 3 Double Ruby symbols, worth 10,000 credits on line 1 or 2,000 on lines 2 to 9. Overall, the BAR symbols cover the lower end, while most of the real value comes from the 7s and the Double Ruby wild.
Special Symbols
Double Ruby Symbol
The Double Ruby logo is the only special symbol in the game. It substitutes for BARs and 7s, multiplies qualifying line wins to 2x or 4x, and unlocks the slot’s top listed award when 3 land on payline 1.
Graphics, Animations & Sound Design
-
Graphics
Double Ruby looks exactly like the game it is trying to be: metallic reels, a deep red backdrop, bright BAR and 7 symbols, and a logo placed cleanly above the grid. We like that it does not crowd the screen with ornamental junk or fake feature markers.
-
Animations
Animation is kept on a short leash. Reels spin, line wins flash, and the logo multiplier effect registers without turning a basic hit into a miniature cutscene. That restraint suits the slot because its appeal comes from speed, readability, and a very clear relationship between symbol result and payout change.
-
Sound Design
The sound design stays in the traditional lane, with bell-style cues and a casino-floor feel rather than a cinematic backing track. That matches the rest of the slot. Everi is not trying to dress Double Ruby up as an adventure game when the whole structure is built around simple reel outcomes.
-
Visual Feel & Interactivity
We find the interface one of the game’s better qualities. The reels sit clear of the control bar, the key numbers stay visible, and the payline structure is easy to read at a glance. That matters in a 3-reel slot where the value is in quick recognition, not prolonged feature tracking.

Double Ruby on Mobile Devices and Other Platforms
Double Ruby translates cleanly to online real-money play because there is so little interface drag in the first place. We are looking at 3 reels, 9 fixed lines, a small symbol set, and a bottom bar with the core controls rather than layers of side features. Public operator guidance lists support across PC, iOS, Windows, and Android mobile, with autoplay settings for 10, 25, 50, or 100 spins. That makes the slot easy to navigate on smaller screens because you are not monitoring bonus meters, expanding menus, or reel modifiers scattered around the layout. We still think wider screens do it more justice, not because the game becomes complicated there, but because the payline map and payout information sit more comfortably when nothing is compressed.
-
Android
Android play makes sense here because the controls are sparse and the reel area stays readable. There is very little UI clutter competing with the symbols.
-
iOS
iOS suits Double Ruby for the same reason: the slot does not ask much from the screen. The main actions are bet adjustment, spin, autoplay, and paytable access.
-
Tablet
Tablet is probably the nicest middle ground. You keep the quick-touch ease of mobile play, but the payline layout and symbol spacing breathe more naturally.
-
Desktop
Desktop gives the clearest overall view, especially when you want the full paytable and controls visible without any compression. For a fixed-line classic, that cleaner spacing still helps.
Optimal Gameplay Tips
-
Use Stable Connection
EssentialThere is no long bonus round to protect here, but a stable connection still matters if you are using autoplay or switching stakes during a real-money session.
-
Landscape Mode Recommended
RecommendedLandscape is the better fit on mobile because the 9-line layout, control bar, and paytable access all sit more naturally across the width of the screen.
-
Audio Settings
OptionalThe sound is straightforward and old-school, so the only real decision is comfort. Set the volume where you can follow wins without turning a long session into background irritation.
-
Full Screen Mode
RecommendedFull screen helps mainly with clarity. You are not revealing hidden features, but you do get a cleaner read on the reels, paylines, and current stake.

About Everi — The Developer Behind the Game
On the company’s official pages, Everi positions its online business around bringing land-based hits online through Spark, its proprietary Remote Game Server. The same pages stress operator configurability, technical stability, and speed to market, which lines up with what Double Ruby actually feels like in practice: a traditional casino-floor game moved online without being loaded up with unnecessary side systems. A 2024 company release says Everi Digital’s online catalogue now consists of more than 100 distinct titles across North America and Europe, which helps explain why the studio can keep supporting both classic formats and newer concepts at the same time.

Spark Delivery
Everi’s Spark Remote Game Server is the platform used to deliver its online content, with an emphasis on configurability, technical stability, and fast operator rollout.
-
Land-Based Roots
The company explicitly frames its digital catalogue as land-based hits brought online, and Double Ruby plays exactly like that kind of transition.

Final Verdict
Why It’s Worth Playing
- The Double Ruby logo is more than decoration, as it can boost qualifying line wins to 2x or 4x
- The paytable is broader than the 3-reel layout suggests because both mixed BAR combinations and mixed 7 combinations already return money
- The $0.90 to $450 stake range gives the slot enough room for small sessions and much more aggressive real-money play
- The interface stays tidy on all devices, with no meters, panels, or trackers taking up space
- Everi rates Double Ruby volatility 3, placing it in the medium range rather than aggressive feature-heavy online slots
Things to Consider
- There are no free spins, no bonus round, no bonus buy, and no ante bet, so feature-driven players will run out of interest quickly
- The biggest listed payout is tied to 1 exact event: 3 Double Ruby symbols on payline 1, not simply anywhere on the reels
- There is no official info about its RTP, so you need to check the exact version in the casino you open
Overall Rating
6.6
Bottom Line
We would not call Double Ruby expansive, but we would call it precise. The game gives you 3 reels, 9 fixed lines, a clear symbol ladder, and 1 logo wild that can turn an ordinary line into something worth noticing. That is enough when the rest of the design stays disciplined. The slot knows it is a classic, and it does not waste time pretending otherwise. We would point it at players who still like BAR-and-7 structure, quick sessions, and a paytable they can understand without a tutorial. We would not point it at readers looking for free spins, feature chains, or a long list of moving parts.

Frequently Asked Questions
Is Double Ruby a real-money pokie?
Yes. Its stake range starts at $0.90 and runs up to $450 per spin. Availability still depends on the casino and jurisdiction.
Does Double Ruby have free spins or a bonus buy?
No. The official game page describes a 3-reel, 9-line slot built around multiplier wilds and a top line payout, with no mention of free spins, bonus buys, or ante bets.
What does the Double Ruby symbol do?
It works as both the top symbol and the game’s special symbol. It substitutes for 7s and BARs in winning lines, paying 2x with 1 logo and 4x with 2.
Is Double Ruby a medium-volatility slot?
Everi lists Double Ruby at volatility 3. In practical terms, that puts it in the medium range rather than alongside the more aggressive high-volatility online slots built around heavy bonus features.
How many paylines does Double Ruby have?
Double Ruby runs on 9 fixed paylines across a 3-reel, 3-row layout. You cannot switch lines on or off, so every spin plays the full line setup the game is built around.
