How Does the Double Ruby Slot Work?
Before starting, players can review the specific mechanics of the Double Ruby slot game by selecting the ‘Menu’ icon to access the help files. Within the ‘Pays/Help’ window, the interface provides details on symbol values, the orientation of the nine paylines, and the gameplay rules.
When ready to begin, the process involves a few simple steps:
- Setting the Bet: Select ‘Bet’ to adjust the stakes. This online slot game allows wagers of 10 to 450 credits per spin, catering to various play styles.
- Starting the Spin: Once the bet is selected, the ‘Spin’ button sets the reels in motion. The game uses a 3×3 grid where symbols must align to form a win.
- Finding a Win: Players achieve wins by landing three matching symbols on any of the nine fixed paylines. These combinations must appear on adjacent reels, starting from the leftmost reel.
- Calculating Payouts: Since all nine paylines are active during every spin, any wins that occur for players on different lines are added together for the total payout of that round.
Double Ruby Game Features
The features in this slot review focus on the utility of the wild symbols rather than secondary mini-games or complex animations.
Double Ruby Wild Multiplier Feature
The Double Ruby slot game symbol acts as a Wild within qualifying combinations. When a Double Ruby symbol appears as part of a winning Sevens or Bars combination, the payout is 2x the listed paytable value. When two Double Ruby symbols appear in a winning Sevens or Bars combination, the payout increases to 4x the paytable value.
Double Ruby Active Payline Feature
Wins in this online slot game must form on active paylines and begin with the leftmost reel. Symbols must land on adjacent reels to create a valid combination, and when more than one active payline produces a win in the same round, those winnings are added together. If multiple winning combinations appear on a single payline, only the highest-value result is paid.
Double Ruby Information and Recall Feature
The interface also includes access to the game’s paytable, rules, settings, and recall history. These options allow players to review symbol values, line rules, and previous game information without leaving the main screen.
Double Ruby Slot Bonuses and Jackpots
While the Double Ruby slot game does not feature a progressive jackpot, it includes high-value fixed rewards tied to the Double Ruby symbols.
The “Top Award” of 10,000 credits is awarded when three Double Ruby symbols land specifically on payline 1. If three Double Ruby symbols land on any other payline (2 through 9), a fixed reward of 2,000 credits is issued. These values are based on the base credit amount and are influenced by the selected bet multiplier. Players can track their potential winnings through the paytable, which displays all values clearly based on current bet settings.

The visual design of Double Ruby emphasizes a retro aesthetic often found in physical MGM-owned casinos. The silver reels are set against a rich, red patterned background, with the game logo prominently displayed at the top. The animations are smooth and functional, mimicking the rotation of mechanical reels. The audio features traditional electronic chimes and mechanical clicks that occur as the symbols lock into place.
