Book of Ruby Features and How They Work 

Book of Ruby Features

Book of Ruby comes with some special symbols and features that will take your gameplay to another new level. Here let’s review each of them in detail.

Retro Bet Feature 

Activating the Retro Bet feature will help you unlock the Multiplier Box feature, which can multiply your earnings by 1x – 5x. This feature remains active until you decide to turn it off. Retro Bet costs an amount equal to your total stake. Moreover, while active, winnings are paid according to the original total stake (without the cost of the Retro Bet feature).

Free Spins – Expanding Symbol

During the Free Spins feature, after the game result has already been determined, the expanding symbol will enter the play to form new paylines in addition to the fixed paylines. However, this symbol will expand only if the expansion will lead to a win. The expanding symbol will pay according to the slot paytable and in all active lines, no matter whether the symbols of the winning pattern are consecutive or not. Expanded symbols generally count separately from the original slot result. 

Special Features – Scatter Wild Symbol

The Wild symbol that appears during the gameplay is also a Scatter and will count as any symbol. Three or more scattered Wilds anywhere on the reels will trigger 10 free spins and pay according to the following paytable:

  • 5 – 250x
  • 4 – 25x
  • 3 – 2x

Bet per line is the same as the game that activated the free spins feature.

Special Features – Free Spins

After the Free Spins feature is triggered, you will be presented with a newly-opened screen. There you need to click the Start button to determine which symbol will be the expanding symbol for the free spins round. Also, Free Spins can also re-trigger and award an additional ten free spins. If you trigger Free Spins while Retro Bet is still active, it will trigger the Free Spins with the Multiplier Box feature multiplying your winnings by 1x – 5x. 

Book of Ruby Mobile Slot

Book of Ruby slot machine is fully optimized for users to enjoy playing it on Apple and  Android devices. All the game features, along with captivating graphics and full-packed functions, are fully preserved when loading it on your mobile gadget or tablet.

Players who prefer the game’s mobile version have two main options: playing via the mobile application or a mobile browser. 

Although both app and browser versions give you a similar gaming experience, you can still consider slight differences when making your final pick. 

The mobile app is the best choice for regular players who can access the slot and its functions with several clicks anytime and anywhere. On the other hand, the browser option doesn’t require any file downloads or installation process, enabling players to enjoy the game straight on their browser.
