Book of Time slot Guide: Canny’s Clockwork Bonus Test

I tested the Book of Time slot at $2.00 a spin to see whether Hacksaw’s cartoon book game had more behind it than just a familiar free-spins format.

Book of Time is a very-high volatility slot from Hacksaw Gaming with 96.13% RTP and 10,000x max win potential. The game features a 5×4 grid, 20 fixed paylines, and two bonus rounds. Aimed at patient bonus hunters who can tolerate long quiet patches while waiting for feature upside.

Key takeaways

Best bonus: It’s a Classic! gave my strongest organic hit, paying $573.40 from a $2.00 stake after two retriggers.
Best play: Standard spins looked safer than cold bonus buys in my test, even though the base game felt thin.
RTP / volatility: The math snapshot is 96.13% RTP, very-high volatility, and a 10,000x maximum win.
Risk note: The base game bled steadily across my 500-spin session, so bonus rounds carry most of the action.
Bankroll note: Even a $2.00 stake produced long dead patches, so sizing down helps you wait for features.

Warning: Very-high volatility means the game can look quiet for long stretches, even when the RTP is competitive.

Final Verdict

Book of Time slot Theme & First Impressions

Book of Time gives the familiar book-slot setup more personality through Hacksaw’s creepy rubber-hose cartoon style. You still get the classic scatter-book idea, but Canny the Can makes it feel stranger than another explorer-temple grid.

Visual style

Hacksaw Gaming turns the theme into a time-travel cartoon, with Canny as the yellow tin-can lead. The reels sit inside a wooden frame against a sunlit forest, and the art has a scratchy vintage tone. You see a one-eyed black mouse, a limp green snake, and a knife left in a fallen animal.

Wooden reel frame with wands and card ranks — The base grid sat settled at a $2 stake.

That mix won’t shock experienced book-slot fans, but it gives the game bite. Time Spinners may catch your eye if you like time motifs, while this one leans harder into weird cartoon horror. You notice that contrast fast when the cheerful forest starts hiding darker symbols.

Insight: Canny the Can is part of Hacksaw’s recurring character world, which helps the slot feel less like a standard book clone.

Bonus settings

The two bonus rounds shift the scene rather than just changing the pay rules. It’s a Classic! moves you into a dark library, where selected symbols can spread across whole reels. What Time Is It? sends you into a marble hall with statues and clocks above the middle reels.

Those scene changes matter because the base setup could feel familiar without them. You get a clearer sense of progression when each feature has its own room, tone, and rhythm. The theme won’t carry a cold session alone, but it gives you something more memorable to watch.

How Book of Time Works

Book of Time is a 5-reel, 4-row slot with 20 fixed paylines, and wins pay left to right from the leftmost reel. You shouldn’t call it a ways game, because the paytable uses fixed lines.

Magic wands line up for a $12 win — The wand line paid $12 on the spin.

The same grid, buy panel, and paytable details stay readable on desktop and mobile screens. Bet levels run from $0.10 to $100.00, while feature buys can exceed the normal bet ceiling. The demo opened on $5,000.00 at a $2.00 stake, which gave me enough room to feel the variance.

Symbol values

At my $2.00 stake, the low card symbols pay modestly. The 10 and J return $10.00 for five, Q and K return $25.00, and A pays $30.00. Those values explain why the base game can feel thin when bonus symbols stay away.

Card rank symbols show low pay values — The low ranks showed their five-symbol payouts.

The higher symbols create the real line-hit interest. Magic wand and wizard hat pay $100.00 for five, while hunting knife and green snake pay $150.00. The black mouse tops the regular symbols at $500.00 for five, which gives you a clear symbol ladder.

Mouse snake knife hat and wand pay board — The mouse topped the regular symbol ladder.

Key Stat: The Book is both wild and scatter, but the Clock Man is a separate scatter for the clock bonus.

Wilds and scatters

The Book substitutes for paying symbols and pays $500.00 for five on its own. It also acts as the scatter for It’s a Classic!, so you care about it more than any regular high symbol. That dual role gives every Book landing a small jolt.

Clock Man works differently. He appears as the base-game scatter for What Time Is It?, while the Clock Activator appears inside that round on reels 2, 3, and 4. You need to separate those roles, because the clock feature runs on its own symbol logic.

It’s a Classic!

It’s a Classic! is the main book-style free-spins round, and it produced my biggest win in the 500-spin test. Three, four, or five Book symbols award 10, 15, or 20 free spins with one, two, or three special symbols.

Book Clock Man and Clock Activator symbols — The feature symbols showed their separate roles.

The game draws those special symbols from the low and high paying symbols. It never selects the Book itself, which keeps the round focused on spreading regular symbols. I like that choice, because it preserves the old book-slot tension without making wilds do everything.

Open book shows ten spins and selected symbol — The round opened with ten spins showing.

Special symbols

Selected symbols receive a golden frame and a colour change. If one lands anywhere on at least three reels, it spreads across those whole reels after normal wins pay. After spreading, it pays anywhere across the grid and can connect through other symbols.

Golden framed symbols mark special selections — The selected symbols changed colour and frame.

That rule gives the round most of its upside. Multiple qualifying special symbols spread and pay one at a time, which can create a layered result. The Book doesn’t act as a wild during that spreading stage, so you still need the selected symbols to do the work.

Strategy Insight: Don’t judge the Classic round too early. One spread can be small, but retriggers and extra selected symbols give it real upside.

Test result

My strongest organic Classic round drew the wizard hat as the special symbol. It retriggered twice, added a second and third special symbol, and ran 15 free spins in total. The final payout reached $573.40, equal to 286.7x my $2.00 bet.

That round changed the whole session. Temple of Torment carries a similar high-volatility lesson, because one feature can rescue a rough base game. If you don’t have patience for that structure, this bonus style may feel punishing.

Bonus Buy Results

The tested bonus buys returned badly, so the buy menu should feel risky rather than like a shortcut. At $2.00, I bought two features on fresh $5,000.00 balances and both landed cold.

Buy menu

It’s a Classic! costs $200.00, which is 100x the bet, and buys 10 free spins with one special symbol. Even More Classic! costs $400.00 for 15 free spins with two special symbols. The Most Classic! costs $800.00 for 20 free spins with three special symbols.

Bonus buy panel lists four feature prices — The buy panel showed four feature prices.

What Time Is It? costs $400.00 and buys the clock round. The Most Classic! is the only card labelled medium volatility rather than high, while What Time Is It? shows very-high volatility. You press BUY, confirm the named round and cost, then the game subtracts the amount.

Bought outcomes

My bought It’s a Classic! round cost $200.00 and selected the magic wand. It spread across the first reel several times, but it never connected strongly across three reels. The round closed on $6.60 after 10 free spins, which is 3.3x bet against a 100x cost.

Golden magic wand lands during free spins — The wand spread sat at $6.20 mid-round.

I then bought What Time Is It? for $400.00. Two Multiplier Clocks spread down reel 3 early, and one spin paid $4.00. Low values kept appearing above the reels, so the round finished at $12.00, or 6x bet.

Total win screen shows $6.60 collected — The Classic buy returned $6.60 total.

Warning: A bonus buy isn’t a shortcut to the good part. In this test, $600.00 in buys returned $18.60 total.

Two cold buy samples don’t prove the menu is bad. They do show how harsh very-high volatility can feel when you pay straight into a feature. I’d treat the buy cards as lottery-ticket options, not a smoother route through the game.

What Time Is It?

What Time Is It? is the clock bonus, where reel-specific wild multipliers can spread from the top of reels 2, 3, and 4. Three Clock Man scatters in the base game award 10 free spins in the marble hall.

Clock round entry screen explains reel multipliers — The clock rules appeared before the round began.

The setting has statues, pale stone, and clocks above the three middle reels. Each clock shows a new time on every spin. That constant reset keeps the round tense, because the same activator position can carry very different value.

Clock activators

Clock Activators can land on reels 2, 3, and 4. When one lands, wild Multiplier Clocks spread from the top of that reel down to the activator. They replace every symbol between the top position and the activator.

Multiplier clocks spread down the third reel — The clock spread paid $4 with seven spins left.

That means vertical position matters a lot. A low activator can fill more of the reel, while a shallow one gives you less coverage. You can feel the round asking for both depth and strong clock values at the same time.

Multiplier values

The possible values are WILD, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 11x, and 12x. More than one Multiplier Clock on the same winning line gets added together first. The total then multiplies the line win.

Insight: Clock multipliers add together before multiplying the line win, so several clocks on one line matter more than one isolated high value.

The Book doesn’t appear in this round, so the clock feature feels separate from the Classic round. Time Spinners also speaks to time-theme fans, but this bonus focuses on reel-specific wild multipliers rather than broad clock dressing. My bought round paid only $12.00, so the concept needs decent values to wake up.

Total win screen shows $12 collected — The clock buy closed at $12 total.

Bonushunt FeatureSpins

Bonushunt FeatureSpins are higher-priced spins with better bonus odds, not guaranteed bonus purchases. At my $2.00 base stake, they cost $6.00 each, which is three times the base stake.

Higher-priced spins

Each FeatureSpin runs at the higher price and is more than four times likelier to trigger a bonus round. The mode stays active until you disable it, so the cost increase can stack quickly. You need to view it as a bankroll-speed choice, not a safety tool.

Key Stat: FeatureSpins are paid spins with higher bonus odds, not a guaranteed feature.

FeatureSpins change the pressure more than the structure. You still spin the same grid and wait for the same bonus triggers. The difference is that your balance moves faster while the bonus odds improve.

Test setting

I left FeatureSpins off for the full 500-spin session. That means my main test ran at the plain $2.00 stake without the boosted spin mode. I wanted the base experience first, because that shows how the Book of Time slot behaves without paid acceleration.

That choice felt right after seeing the buy results. Faster bonus hunting can help if you accept the cost, but it can also turn a slow bleed into a faster one. For this game, I’d rather size the stake down before turning FeatureSpins on.

How It Played

The 500-spin test ended only $99.60 down, but the balance path felt much rougher than the final number suggests. I played 500 spins at $2.00, started with $5,000.00, and finished with $4,900.40.

Session swing

The first 250 spins bled steadily to $4,541.00. Then three Books landed and dropped me into It’s a Classic!, with the wizard hat selected. That round retriggered twice and paid $573.40, pushing my balance above the start to $5,114.40.

That high point didn’t last. The final 200 spins ground the balance back down, and a second Classic round landed late. It looked hopeful with $42.00 showing and two free spins left, but it never became a major save.

Base-game feel

The base game didn’t hold the balance up on its own. You need patience and stake control here, because the regular line hits rarely create much cushion. Strength of Hercules shares that rough high-volatility pressure, where the base game mainly buys time until a stronger feature arrives.

My honest read is simple. One good bonus kept the loss manageable, while the plain spins kept asking for more bankroll. Test pages and game figures are checked regularly, but the lesson from my session doesn’t need a date stamp.

RTP, Volatility & Our Test

Book of Time has 96.13% RTP, very-high volatility, and a 10,000x maximum win, so the math supports big swings rather than steady base-game returns. The in-game meter shows five bolts, and both bonus rounds can reach the cap.

If the 10,000x cap hits, the round ends immediately and any remaining free spins are discarded. That rule matters because it limits the top-end outcome, even when multipliers or spreading symbols still have spins left. The ceiling is strong, but it doesn’t make the base game gentle.

Simulator projection

The SatoshiHero Slot Simulator modelled 1,000 spins at $2.00 on 96.13% RTP and very-high volatility. The median session finished $210.80 down. The 5th to 95th percentile band ran from $873.50 down to $1,345.70 up.

Blue curve models one thousand spin outcomes — The simulator curve showed the wider spread.

About 14% of spins returned something. A bonus-tier round appeared about once every 54 spins, while a 100x+ win appeared about once every 812 spins. That spread describes outcome shape, not a prediction for your next session.

Warning: Very-high volatility means a result near break-even can still feel rough if the balance bleeds for hundreds of spins before one bonus lands.

Our 500-spin session

My 500-spin session started at $5,000.00 and ended at $4,900.40. The result was a $99.60 loss, with two organic bonus rounds across the test. The biggest hit was $573.40, or 286.7x bet, from It’s a Classic!

Gold balance line ends at $4,900.40 — My balance finished $99.60 below the start.

Two organic bonuses in 500 spins sat close to the simulator’s expected bonus frequency. Wings of Horus may draw fantasy-slot fans comparing RTP and volatility choices on SatoshiHero, but this game’s sharper edge comes from its split bonus design. The math suggests you should expect long dry runs and sudden feature-led swings.

The theoretical RTP is the operator’s published figure, while a single 500-spin session doesn’t change or prove that return. Bonus-buy RTPs differ slightly from the base game by design, but all sit close to the 96.13% base figure.

Frequently Asked Questions About Book of Time

What is the RTP of Book of Time slot?

The Book of Time slot has 96.13% theoretical RTP on the in-game rules page, calculated over ten billion simulated rounds. The bonus-buy RTPs sit close to it: It’s a Classic! 96.39%, Even More Classic! 96.35%, The Most Classic! 96.37%, What Time Is It? 96.25%, and Bonushunt FeatureSpins 96.27%.

How does the Book of Time slot It’s a Classic! bonus work?

Three, four, or five Books award 10, 15, or 20 free spins with one, two, or three special symbols. The selected symbols get golden frames, can spread across full reels when landing on at least three reels, and then pay anywhere. Three more Books add five spins and another special symbol.

What do the clocks do in the Book of Time slot What Time Is It? round?

Clocks sit above reels 2, 3, and 4, then set the value of wild Multiplier Clocks when an activator lands. Values run from WILD through 12x. If several Multiplier Clocks land on the same winning line, the game adds them first, then multiplies the win.

What did the Book of Time slot 1000 spin simulation show?

The 1,000-spin simulation at $2.00 showed a median result of $210.80 down. The 5th to 95th percentile band ran from $873.50 down to $1,345.70 up. About 14% of spins returned something, bonuses appeared around once in 54 spins, and 100x+ wins appeared around once in 812 spins.

How did the real 500-spin Book of Time slot session go?

I started with $5,000.00, played 500 spins at $2.00, and finished with $4,900.40. That left me $99.60 down. My biggest hit was $573.40 from It’s a Classic!, equal to 286.7x my bet.

Are the Book of Time slot bonus buys worth the money?

My two tested buys came back cold, so I’d treat them as high-risk samples. The $200.00 It’s a Classic! buy returned $6.60, while the $400.00 What Time Is It? buy returned $12.00. The menu also offers Even More Classic! at $400.00 and The Most Classic! at $800.00.

What is the maximum win in Book of Time slot and how is it reached?

The maximum win is 10,000x the bet. Both bonus rounds can reach it through spreading special symbols in It’s a Classic! or stacked Multiplier Clocks in What Time Is It? When the cap hits, the round ends immediately.

What is the Book of Time slot about?

The Book of Time slot is about Canny the Can inside a twisted time-travel book setup. The base game uses a forest scene, It’s a Classic! moves into a dark library, and What Time Is It? shifts into a marble clock hall. It’s not about reading order or novels.

Final Verdict

Book of Time stands out because it mixes a classic book-slot format with Hacksaw’s stranger cartoon world. The main drawback is clear: the base game can feel weak until a bonus round lands. Book of Time gives you numbers worth respecting, but it asks for discipline.

My Take

I’d play this with a smaller stake than my $2.00 test if I wanted a longer session. The bonuses have real upside, but the base game doesn’t soften the waiting. Patient bankroll managers get the clearest value from the structure.

I like the Classic round because one retrigger chain changed my full test. I don’t like how the buy menu treated me, with $600.00 spent and only $18.60 returned. That felt harsh, but not unrealistic for this volatility level.

The Book of Time slot is a strong pick when you want feature tension, exact math, and a weird visual identity in one package. My figures and feature notes are updated periodically, and the central warning remains the same: don’t chase the bonus at a stake your bankroll can’t support.

Pros:

Strong Feature Ceiling: The 10,000x cap gives bonus rounds serious upside.
Clear Math: The 96.13% RTP keeps expectations easy to compare.
Distinct Art: Canny’s creepy cartoon style avoids plain book-slot sameness.
Useful Test Data: My 500-spin result shows real balance pressure.

Cons:

Thin Base Game: Regular spins struggled to protect my balance.
Cold Buy Risk: My $600.00 in buys returned only $18.60.
Harsh Variance: Very-high volatility can punish oversized stakes quickly.

Best For: High-volatility hunters, feature chasers, and patient players get the most from this slot. You need comfort with long quiet runs, because the biggest swings come from It’s a Classic! and What Time Is It? Theme fans also get more personality here than in a plain temple book game.
