Toro and Matador Head to Egypt in ELK Studios Take on the Classic Book Style Slot!

ELK Studios are celebrating five years of the popular Wild Toro slot series. Last month saw the release of the highly anticipated sequel Wild Toro II, and this month we are set to receive their intriguing take of a "Book-style" slot featuring Toro once again in the Book of Toro slot.

The scheduled release date for the Book of Toro is the 2nd of November 2021, so you will find this playable already in great casinos such as Mr Green, who has a full range of ELK studio slots!

The backstory sees the intrepid duo Toro and the Matador head over to Egypt on a quest to prevent Matador Diaz Jr's ancestor, the evil Captain Diaz, from finding the Book of Toro.

If there was ever a tentative plot setting for an Ancient Egyptian book themed slot, it might just be this machine, but there does seem to be enough tweaks and novel additions to the gameplay to explore this machine further!

Book of Toro Slot - Base Gameplay

On first inspection of Book of Toro, you have a very true to an original "Book Style" of slot. A 5x3 reel layout, ten fixed paylines that are numbered next to the reels, similar to the classic Novomatic Book of Ra Deluxe. The usual Book (Scatter/Wild) symbol and a randomly chosen Expanding Symbol during the free spins that can produce some massive hits.

Pretty much all of what you should expect in a Book slot has been incorporated here, with several additions that make this slot worth investigating.

The first noticeable difference is the addition of semi-stacked symbols on all the reels, with a hit frequency of 23% means that this slot doesn't feel as brutal as some of the higher variance book machines. It's still volatile, but our playtests indicate it is not as severe as some of the new book slots.

However, the most significant difference to this machine is the introduction of the Wild Toro symbol and the Mummy symbols. The combination of both of these symbols triggers the Toro Goes Wild feature, triggering a walking wild feature capable of several wild reels in the base game and even acting as an expanding symbol during the bonus round.

This provides some excellent base game hit potential along with a really novel twist if this feature triggers whilst in the free spins.

Other nice touches include sticky wilds that are held on the reels while this feature plays out. Since these symbols are Scatters and Wilds, this gives you an added tease of an easier to trigger bonus feature.

To truly appreciate how the addition of the Toro Goes Wild feature affects gameplay, you probably have to see it in action. The base game version is excellent and keeps the slot full of anticipation, but triggering this feature in the bonus round completely transforms the bonus round into a different beast!

Book of Toro Special Features

The general playstyle of the Book of Toro plays out as you would expect a typical Book slot, with expanding symbols during the free spins, decent 5 of kind payline wins, and full bonus re-triggers a possibility, with the addition of extra symbols also being awarded when this occurs.

The key differentials on this machine are the Mummy Respins and the Toro Goes Wild feature and the way this can be activated during the main free spins bonus round.

Book Symbol

The Toro Book Symbol acts as not only a Wild but also a Scatter symbol, just like all other Book slots.

Landing 3 of these anywhere on the reel triggers the main free spins bonus round or will re-trigger the bonus round during the free spins.

Mummy Respin Feature

The Mummy Respin feature triggers when two or more of the Mummy symbols land in view during a spin, a respin of the reels occur and if any new Mummy symbols land in sight, the respin process continues.

Ideally, though, once the Mummy Respin feature activates, you are looking for the Toro Wild symbol to land in view, which then triggers the Toro Goes Wild feature.

Mummy Symbol

Mummy Symbol

Toro Goes Wild

The Toro Wild symbol is the key symbol required to land during the Mummy Respins. This triggers the Toro Goes Wild feature, a walking wild with respins that converts all mummy symbols into wilds.

Once this feature is activated, the wild symbol walks across the reels one reel at a time, giving you several re-spins until it is removed off the first reel.

Toro will charge to the position of any Mummy symbols and convert all symbols in his path into wilds. During this re-spin feature, any regular wilds are held sticky on the reels too!

The sticky wilds are the ones that are required to trigger the main bonus feature, so this novel interaction can really help boost your chances of a bonus trigger.

Free Spins

The free spins round plays out like a regular book slot. Once triggered, you are randomly awarded a unique Expanding Symbol, highlighted in Gold for the bonus round.

  • 3 Book Symbols - 10 Free Spins
  • 4 Book Symbols - 15 Free Spins
  • 3 Book Symbols - 20 Free Spins

When these golden symbols land in view during the bonus, they will expand and pay in a scatter like fashion across all ten paylines.

The key addition to this slot is that the Toro Goes Wild feature can activate during this bonus as well, and this makes the Toro Wilds act as expanding symbols as well (see earlier screenshots) with a mix of regular expanding and wild expanding symbols, making it much easier to land several in view.

The free spins counter is also paused while the Toro Goes Wild feature plays out, in essence, these re-spins do not count toward the free spins used.

Full bonus retriggers are also possible, and this not only awards ten more free spins but further expanding symbols into the bonus round (Max of 3 Symbols).

X-iter Feature

The X-iter features are in essence ELK Studios take on the Bonus Buy features, as such limited to specific countries where allowed.

These options are stake based options to bypass the base gameplay and skip straight into the various feature.

These can range from a 5x Bet spin for a guaranteed Mummy Respin to a whopping 500x stake super bonus with sticky expansion symbols.

  • Mummy Respins - one spin with a guaranteed Mummy Respin -  Cost  5x
  • Toro - one spin with a guaranteed Toro Goes Wild - Cost 25x
  • Mini Bonus - 3 spins with a randomly selected gold expansion symbol -  Cost 50x
  • Bonus  - Free Spins Bonus Trigger  - Cost 100x
  • Super Bonus - Free spins bonus with all book symbols acting as sticky wilds. Expanding symbols are also kept sticky if additional symbols land, Progressive Multiplier - Cost 500x


The paytable displayed below shows the symbol win payouts based on a €4 stake size. Compared to regular Book slots, these values seem to be a little lower, especially for the highest paying premium symbols, which generally pay 500x for 5 of a kind. In this slot, however, it is 250x stake.

With the addition of the Toro Goes Wild feature and the base game hit potential, as well as the enhanced bonus round and ease of getting matching symbols, this seems to be a fair trade-off.

Book of Toro Slot Final Opinions

The Book of Toro is a fantastic take on the classic Book style slot from ELK Studios. Whilst the core gameplay and “Book Style” has been retained, the introduction of more heavily stacked symbols and the Mummy Re-Spins and Toro Goes Wild feature really help break up the gameplay.

The Toro Goes Wild feature is the highlight. Not only does it allow some excellent base game hits, but with the wild symbols acting sticky during this feature, it can tease with a potentially easy bonus trigger afterwards. This walking wild feature truly shines in the free spins round by giving extra spins as Toro progresses over the reels and activating wilds as expanding symbols in addition to the chosen book symbol.

The combination of these clever interactions is just a great touch that makes this slot engaging to play. Whilst the winning potential of this slot can be achieved with a completely regular Book bonus round and premium symbol, the true excitement and anticipation occur when a good symbol has been chosen, and you manage to activate the Toro Goes wild during the bonus round!

Full screens of symbols and re-triggers seem harder to get than a regular book slot such as Book of Ra Deluxe or Book of Dead. Still, on the flip side, the Toro Goes Wild and Mummy Re-Spin offer great base game hit potential and something genuinely different during the bonus round.

If you are lucky enough to be able to play with the bonus buy options (X-iter Features), be sure to check out these modes in demo play first. The Super Bonus Buy transforms the bonus round to a crazy level of excitement and potential with rising multipliers and semi-sticky symbols, but at the cost of 500x, it’s one option you need to test first!

If you are a fan of Book Slot, definitely take this one for a spin as the balance of core book gameplay and new features is just about spot on!
