Overall Score


One of the weirdest takes on the Book of ... series of slots that is hard to love but does offer a unique free spins round format that has big potential.

About Book of Time

Hacksaw Gaming’s oddball mascot, Canny The Can, is back in their interpretation of the ‘Book of …’ game format. This slot was released in November 2022 and in typical Hacksaw and ‘Book of’ style operates at a high volatility. This was the second time-themed slot released by the studio in 2022, following their eerie Time Spinners game from the summer. But where that game had a dark and ghoulish side, Book of Time is an eccentric mix of styles and gameplay with the volatility dialled up to the max, of course.

  • Unique What Time Is It? bonus round

  • Has potential for big wins

What We Didn't like

Theme, Artwork & Design 7/10

Games featuring ‘Canny the Can’ are something of an acquired taste. The style is like a Disney cartoon from the 70s, though quite why it features a can, who knows?! In this case the setting is a countryside scene though the symbols and free spins round suggest a witchcraft element with witches hats, snakes heads and wands. All the while … a relentlessly plinky-plonk piano loop soundtracks your play.

It’s quite a jarring collection of ideas and certainly nothing like the classic Ancient Egyptian iconography of the Book of Dead or the horror fest that is Nolimit City’s Book of Shadows. But then, this is Hacksaw and they like to do things differently.

You will either love it or hate it!

RTP and Variance 7/10

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

There are four variable RTP settings for Book of Time: 96.13%, 94.34%, 92.33% or 88.25%. Which you play at is at the discretion of your casino operator. We checked the RTP at four UK slot sites. This is what we found:

  • Dream Vegas (White Hat Gaming): 94.34%
  • MrPlay (Aspire Global): 92.33%
  • MrQ (independent): 96.13%
  • Casumo (independent): 94.34%
  • BacanaPlay (Skill on Net): 92.33%

The best value gameplay you can get from those is MrQ who are running Book of Time at its optimum RTP level.

Book of Time is a high variance slot so it will be a tough play with some frustrating sessions. That puts it in the same category as slots like Time Spinners and Hand of Anubis.

Maximum Win 8/10

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

Book of Time has a maximum win of 10,000x. That is average for high risk Hacksaw Gaming slots. They rarely exceed this threshold. If you want bigger max wins you should look at games from suppliers like Big Time Gaming and Nolimit City.

Paytable 9/10

Book of Time plays out on a 5×4 reel set with 20 fixed paylines active at all times. Wins are tiggered by landing three or more identical symbols on the reels from left to right along a payline starting with the left most reel.

This game is notable for high symbol values.

Low payers are the cards 10 through to Ace. They are valued at between 5x and 15x for five on a payline. The high value symbols are the wand, the hat, the knife, the snake and the mouse. These are valued at between 50x and 250x for five on a payline.

In keeping with the traditions of Book of slots, the Book symbols is both scatter and wild. It subs in for all other symbols to complete win lines AND triggers the bonus round. However, importantly it does NOT act as a wild during those bonus rounds.

There is also a Clock Man scatter which can trigger the What Time Is It? Bonus round where the game diverges from tradition in all kinds of fun ways. More on that in a moment.

Gameplay & Features 8/10

It’s a Classic – The ‘Classic’ Book of Bonus Round 

Hacksaw bow to convention with the first bonus round in Book of Time. Land 3 or more Book scatters and you’ll earn yourself 10, 15 or 20 free spins as follows:

  • 3 Book Scatters: 10 free spins and ONE special symbol
  • 4 Book Scatters: 15 free spins and TWO special symbols
  • 5 Book Scatters: 20 free spins and THREE special symbols

The special symbol is chosen at random and may be any of the standard symbols but not the Book itself. To activate special symbols, which now appear with a frame around them, you will need to land one on each of at least THREE reels.

When activated, after payouts are completed for a spin, the special symbols expand to full reel height, and trigger more pays if they complete win lines. They can also connect to create wins even when other symbols fall between them.

What Time Is It? – Crazy Alternative Bonus Round

Ok, so this is Hacksaw and it was never going to be straight forward! Landing 3 Clock Man scatters triggers another bonus round called What Time Is It?

Now you get 10 free spins with clocks appearing above reels 2, 3 and 4, indicating a different time on every spin. You are now looking for Clock Activator symbols to land anywhere on reels 2, 3 or 4. When they do, Multiplier Clock Wilds expand downwards from the top positions until they reach the row with the Activator on. The value of the multiplier is the same as the time on the clock … from 2x right up to 12x! Of course!

Finally, Multiplier Wilds are added together then more than one forms part of a winline.

More Games Like Book of Time Slot

Book of Shadows by Nolimit CityBy far our favourite Book of game and one that in my opinion outclasses Book of Time is Book of Shadows. NLC have given the series a ghoulish twist with this version that has elements of The Ring or Blair Witch about it as it features an undead girl. It has a higher variance and a bigger top win of 30,388x.

Time Spinners by Hacksaw GamingBefore Book of Time, Hacksaw were confounding us with Time Spinners, an equally volatile beast and one with an eerie dungeon setting. The name of the game is landing multipliers and the Dusk til Dawn Bonus round gives you the chance to land sticky multipliers of up to 12x that can push payouts as high as 10,000x.

You can easily search for your favourites using the game provider filter or by game name. Dream Vegas currently offer a 100% match up to £300 and 150 spins on Aloha!

Boom or Bust? What Happened When We Played Book of Time

I played Book of Time over 60 minutes on Dream Vegas at 10p a spin. Here is what happened.

  • Session Time: 60 minutes
  • Bet Size: 10p
  • Start Balance: £21.02
  • End Balance: £0
  • Net Win / Loss: –£21.02
  • Biggest Single Win (excl. Free Spins): £8.50 (85x)
  • Free Spins Round Feature Triggers: Two
  • Biggest Free Spins Round Wins: £2.66

This was a tough session with only two free spins rounds triggered – both Classic mode – and NO What Time Is It? Bonus Round. Wins felt quite irregular and maxed at 85x in the base game.

It’s hard to write positively about a game that offered so little for so long. But those are the breaks. Like all Book of slots, if things aren’t going your way they can feel very monotonous and frustrating. And with Canny doing his dance and the plinky backing track it felt like a weird low budget Saturday night gameshow at times.

When I did break the bonus round the spins go by quickly and first time I won just 13p. Second time, I landed three more Books and opened up a second special symbol. But even then, the payout was just 26x.

In all, this is a strange game. Canny looks like he doesn’t belong in this setting and whilst bad runs happen sometimes, there just wasn’t enough to keep me entertained in this one to take the edge of the losing streak.

It will be a while before I come back to Book of Time.

Our Verdict 7.6/10

Book of Time is an eccentric slot that will split opinion like marmite. For me, the odd mix of styles and gameplay and the oddity that is Canny the Can just jarred with my expectations of what a Book of slot might be. I’m all for experimentation, but in this case, it hasn’t worked. But it’s for you to decided, and die hard Hacksaw fans, and those with peculiar tastes, might just find Book of Time to be worth a spin.
