Book of Slingo game review

Last Update: 10.10.2022. Author: SlotCatalog.

Given the popularity of the Book of … genre, it’s a bit strange that Slingo Originals have waited so long before they finally launched their slot/bingo hybrid take on the favored mechanic. Needless to say, they went with the classic ancient egypt style visual presentation, and they’ve not taken any innovative chances with the bonus round either.

As usual, you move up the slingo bonus ladder by completing lines in all directions, and anything below 8 slingos will only award smaller cash prizes. The bonus round comes with a higher tier expanding symbol the more slingos you get, but you can also trigger the feature directly by landing scatters on the regular 5x1 slingo reel.

Book of Slingo Features

The slingo game comes with a pretty standard set of special symbol features. Regular wilds allows you to mark off any position on the above column, while the Super Wild allows you to mark off any position on the whole grid.

The best strategy is to always mark off positions that either give you a slingo directly, get you closer to a slingo, or positions that can generate more than one slingo down the line (corners and the center position). Indefinite extra spins can be purchased for an individually calculated price, after your initial 11 spins are finished.

You can also land free spins symbols on the 5x1 reels, and this gives you +1 extra spin on top of the 11 you get by default. The ‘X’ is a blocker symbol, and it does nothing but take up valuable space on the reel. Finally, you have the Book scatter symbol, and at least 3 of these on the same spin trigger the bonus round as follows:

  • 3 book scatters award 10 free spins where any symbol can be chosen as the special expanding symbol.
  • 4 book scatters award 10 free spins where only the premium symbols can be chosen to become the expanding symbol.
  • 5 book scatters award 10 free spins where you get the top paying Eye of Horus as the chosen expanding symbol.

The other way to get to the bonus round is to get at least 8 slingos. All bonus round tiers come with 10 free spins, but the special expanding symbol increases in value the higher you go. 8 slingos gives you the lowest value premium symbol as the expanding symbol, while a full house awards the top paying Eye of Horus symbol as the expanding symbol.

The bonus round plays out with the classic ‘Book of’ mechanic. The chosen symbol will thus expand after the regular win calculation, if you land enough instances anywhere to generate a win. This gives you an extra expanded symbols payout, and a full screen of the top-tier Eye of Horus symbol awards 500x your stake. You also get 10, 15 or 20 extra spins when you land 3, 4 or 5 book scatters, respectively.

The 200 Spins Book of Slingo Experience

We paid our way to a full house with rather costly extra spins, and this gave us the top tier bonus round. The feature plays out from 2:17 into the almost 4 minutes highlights video, and you can check it all out for yourself by hitting the play button below.

Review Summary

We almost wonder what took them so long, as a ‘Book of’ mechanic slot/bingo hybrid was bound to happen sooner or later. Unlike most slingo games, you can actually trigger the bonus round directly from the main game here, without even getting a single slingo first. However, you will need at least 8 slingos to get the lowest tier bonus round, which is pretty hard with no paid extra spins.

The question is, will players prefer this to a regular ‘Book slot’, not least since the top single spin payout is 10x less than the usual 5,000x your stake. Most of the time you will hardly get a slingo or 2 before you need to pay for extra spins. Granted, these are not too costly at first, but when you close in on the 8 slingo bonus round trigger, you will pay around 10-14 times your original stake per spin. Not exactly cheap, only to get a bonus round with a low to medium paying expanding symbol.

Pros

  • Slingo w/ ‘Book of’ mechanic bonus round
  • Trigger bonus round directly from main game
  • Climb ladder to get a higher value expanding symbol

Cons

  • Single spin max win is only 500x your stake
  • Hard to get enough slingos without plenty of paid extra spins

If you enjoy Book of Slingo you should also try:

Pay of the Dead - the title might sound familiar, but this is no ‘Book of’ slingo game. You can look forward to a bonus round with wild multipliers, as well as a pick’em multiplier game. Celebrate the macabre day of the dead carnival with style, and win up to 10,000x your stake.

Book of Dead - is the Play’n Go title that started the whole ‘Book slot’ frenzy, and it’s yet to be dethroned by the countless clones that have followed in its wake. It’s all about the bonus round where a random symbol is chosen to be the expanding scatter win symbol, and payouts up to 5,000x can be landed on a single spin.

Slingo Rainbow Riches - is another classic slot that’s been converted into the slot/bingo hybrid concept. It comes jam packed with different irish luck bonus features, and the bonus ladder awards 7 unique feature triggers. This can lead to payouts up to 1,000x your stake.
