Book of Time Is a Patience Test Disguised as a Slot

If you’re playing this on a £20 deposit, close this tab. I’m serious. Book of Time by Hacksaw Gaming is a 5×3, 10-payline game that will eat through a small bankroll like it’s nothing, then hand someone else a 340x bonus while you watch your balance flatline. That’s the deal. You accept it or you don’t.

The time-travel theme is window dressing — ancient symbols, a mystical book, historical imagery that looks good but doesn’t change what this actually is: a brutally volatile scatter-chaser. If you’ve played Bloodthirst, you know the feeling — long stretches of nothing punctuated by moments that justify the entire session. Or think of Book of Dead by Play’n GO, which has similar bones but honestly feels tame by comparison. Book of Time swings harder in both directions. The highs are higher. The lows are lower. The middle ground doesn’t really exist.

A user on CasinoGrounds put it perfectly: “either a coffin or a rocket — there’s no middle ground.” That’s the most honest review of this game I’ve seen.

How It Actually Plays (Not What the Paytable Tells You)

Spin to spin, here’s what actually happens: you’re playing 10 fixed paylines on a classic 5×3 grid. No Megaways, no cascades, no cluster mechanics. This is old-school structure with modern volatility math layered on top. The base game is functionally useless. You’re here for the bonus and nothing else.

The variance math here is interesting. Let me break down what the numbers actually mean for your session:

• RTP: 96.35% — Decent on paper. But with very high volatility, that return is concentrated in rare events. Most spins return less than you’d expect from a 96% game.
• Hit frequency in base game: You’ll get small wins regularly enough to slow the bleed, but they’re almost never meaningful. Think 0.5x to 3x stake, scattered across dead zones.
• Dead spin runs: In my 250 spins of testing, I had a cold streak of 65 consecutive spins with no feature trigger. That’s not unusual. Runs of 60-80 dead spins between features are completely normal.
• Max win: 10,000x — Achievable but statistically rare. Think about what that means for your session: you’re grinding for a low-probability event that could pay life-changing money relative to stake, or nothing at all.

A typical session feels like slow suffocation. Your balance drains at maybe 60-70% of starting stack before a feature hits, and then you’re either back in the game or you’re dead. There’s no gentle recovery arc. The game doesn’t do gentle.

The Bonus Round: The Book Feature That Defines Everything

Three scatter symbols trigger the free spins feature. Before the round starts, a special expanding symbol is chosen — it can expand to cover entire reels during the free spins, which is where the big money lives. This is the entire game. Every spin you take in the base game is just a ticket purchase for this moment.

Here’s my actual data from 250 demo spins. I triggered the bonus 3 times. The distribution:

• Bonus 1: 28x stake. Low-value expanding symbol, never filled more than two reels. Disappointing.
• Bonus 2: 47x stake. Mid-tier symbol, got a decent three-reel expansion on spin 6 of the feature. Reasonable.
• Bonus 3: 340x stake. Premium symbol selected, full screen hit on the final spin. This is the one you screenshot.

Three bonuses across 250 spins means roughly 1 trigger every 83 spins. That’s consistent with what I’d expect for this volatility class. Players on forums have reported bonus pays anywhere from 8x to 900x, which tells you everything about how brutal the variance is. The expanding symbol selection is the first coin flip — get a low-pay symbol and your ceiling drops immediately.

What 100 Spins Actually Looks Like

I ran a tracked 100-spin session at £1 stake, starting balance £100. Here’s the reality:

• Spins 1-25: Scattered small wins. Balance: £82. Nothing interesting happening.
• Spins 26-50: Complete wasteland. One win of 2x stake at spin 34. Balance: £61. Starting to feel it.
• Spins 51-70: Two small hits, both under 1.5x. Balance: £44. This is the grind people don’t post about.
• Spin 71: Three scatters land. Bonus triggered. Expanding symbol: second-tier. Feature pays 47x. Balance: £91.
• Spins 72-100: Back to the grind. A couple of minor wins. Final balance: £74.

Without that bonus? We’d have ended at roughly £27. One feature hit was the difference between a manageable loss and a wipeout. That’s Book of Time in a single data point. The game’s entire economy runs through the bonus round — the base game just determines how slowly you die before you get there.

Should You Actually Play Book of Time?

Play Book of Time if:

• You understand volatility math: This is a game for players who know that 10,000x max win comes with sessions of absolute nothing. You’re comfortable with that tradeoff.
• You have the bankroll: Budget minimum 150x your stake. At £0.20 spins, that’s £30. At £1 spins, that’s £150. Non-negotiable.
• You like Book-style mechanics: If you’ve played Book of Dead, Book of Ra, or any expanding-symbol-in-free-spins game and enjoyed it, this is a sharper, more volatile version of that formula.
• You want high-ceiling sessions: The 340x I pulled is nowhere near the ceiling. For UK players who want that potential, this delivers more than something like Benny the Beer which caps out lower.

Skip this slot if:

• You’re on a tight budget: Anything under 150x stake and you’re gambling on getting the bonus before your money disappears. That’s not strategy, that’s prayer.
• You want a bonus buy option: There isn’t one. Scatter trigger only. If you need that shortcut, look elsewhere.
• You’re clearing wagering requirements: Very high volatility and wagering requirements do not mix. You’ll either bust your bonus or hit a win you can’t withdraw yet. Read about common casino bonus mistakes before attempting this.
• You prefer session consistency: Something like Booze Bash gives you more regular engagement. Book of Time gives you nothing and then everything.

How It Compares to Similar Slots

Book of Time sits at the aggressive end of the Book-style spectrum. Book of Dead is the safe choice — lower max win, similar structure, more predictable sessions. Book of Ra is the nostalgia pick. Tome of Madness is for people who want the theme without the punishment. Book of Time is for people who looked at all of those and thought “not enough variance.” Most people miss this: the absence of a bonus buy on Book of Time actually changes the maths of your session planning entirely. You can’t shortcut to the feature, so bankroll management becomes everything.

Strategy Tips

1. Set a 150x minimum session budget: This is non-negotiable for very high volatility. If you’re playing £0.50 stakes, bring at least £75. Anything less and you’re likely dead before the first bonus.
2. Play for the bonus, ignore the base game: Base game wins are life support. They slow the bleed. Don’t get excited about a 3x hit — it means nothing in the context of this game’s economy.
3. Don’t chase after a dry run: 80 spins without a bonus is normal. It’s not “due.” The next 80 spins have the same probability as the last 80. Walk away or reduce stake if you’re tilting.
4. No bonus buy means patience is the mechanic: You can’t buy your way in. That actually makes proper session planning more important than on games with feature purchases. Plan your exit before you start.
5. Avoid this for wagering clearance: I’ll say it again — very high volatility and bonus wagering are a terrible combination. If you’re sitting on a no deposit bonus with 40x wagering, play something with lower variance. Read about casino bonus mistakes before you learn this the expensive way.

The Bottom Line

Book of Time is a 10,000x ceiling attached to 80 dead spins of nothing.

That’s not a criticism. That’s the design. Hacksaw built this for players who understand what very high volatility actually means in practice — not the marketing version, the spreadsheet version. If you have the bankroll, the patience, and the stomach for long dry runs, this is one of the sharper Book-style games available. If you want consistent entertainment, this will make you miserable. Simple as that.
