Book of Inferno Bonus Features

Book of Inferno incorporates tried and tested features inspired by its hugely popular predecessors. As such, if you’ve ever played a ‘Book of’ slot before, you’ll be familiar with what’s on offer. Book symbols act as both Wilds and Scatters, while special expanding symbols are introduced whenever you trigger the free spins bonus. However, Quickspin has decided to freshen things up somewhat by also including Marked symbols to spice up the base game.

Scatter Wild Symbol

Wilds and Scatters appear as the same symbol in Book of Inferno, a demonic tome. If they land as part of a winning combination, they will substitute for all regular paytable symbols to complete the win. Additionally, 3 or more Books landing during a single spin will trigger the free spins on Book of Inferno.

Marked Symbols

Randomly during the base game, the Marked symbol feature can trigger to give you a taste of what the free spins bonus has to offer. This marks an individual symbol, which will then expand and pay in any position if the required number of symbols land. Furthermore, if a Book symbol lands together with a Marked symbol it will upgrade the Marked symbol by one step, potentially creating more Marked symbols and expansions.

Free Spins

To trigger the free spins bonus you’ll need to land 3 or more Book symbols during a single spin – the more that land, the more free spins you’ll receive, as follows:

  • 3 Book symbols: 10 free spins and x2 bet win
  • 4 Book symbols: 15 free spins and x20 bet win
  • 5 Book symbols: 25 free spins and x200 bet win

Upon activating the bonus, a random symbol will be selected as Marked. Whenever enough Marked symbols land, they will expand to cover the entire reel and then award the respective payout, irrespective of their reel positions.

You can also retrigger the feature by landing 3 or more Books. This will award the same number of free spins as the initial trigger.

Buy Feature

If you’d rather skip the base game entirely, you can use the Feature Buy function to head directly to the free spins bonus for the cost of 125x your current stake. Note that this option is only available in certain jurisdictions and is unavailable to UK players.

Book of Inferno Jackpot

Although Book of Inferno hasn’t got a dedicated jackpot prize, you can still land a phenomenal payout due to the game’s 5,846x maximum win.

RTP and Volatility

‘Book of’ games tend to come with a high volatility rating, and Book of Inferno isn’t any different – you’ll want to be cautious if you’re playing with a limited bankroll. That doesn’t mean you can’t walk away with a decent prize though. This slot’s 96.15% RTP falls comfortably in line with the industry average so, hopefully, you’ll see some decent returns as you play.
