A Familiar Tomb With a Fresh Glimmer
It seems no slot genre is quite as enduring as the “Book of…” formula, especially when draped in the golden glow of Ancient Egypt. The Lost Book by Redstone Gaming doesn’t try to rewrite the papyrus, but it does aim to honour the classics—with polished visuals, an enticing bonus round, and some seriously respectable win potential.
The concept? Another mystical tome hidden in a tomb of riches, ready to reveal its secrets to the worthy. It’s familiar territory, but like a well-loved relic, it still gleams under the right light.
Gameplay & Mechanics: Classic Structure, Clean Execution
The Lost Book features the tried-and-true setup fans have come to expect:
- A 5×3 reel layout with 10 paylines.
- The Book symbol serves as both Wild and Scatter.
- Land 3 Book symbols to unlock 10 Free Spins.
- One special expanding symbol is randomly selected for the bonus round.
- Expanding symbols pay even on non-adjacent lines—classic “Book of” mechanics.
Where The Lost Book really sets itself apart is in its Bonus Round animation—a superbly rendered sequence that feels more like a cinematic reward than a slot feature. It’s a visual payoff that makes hitting Free Spins not just profitable, but genuinely thrilling to watch.
Features & Bonuses
- Free Spins with Expanding Symbols: Core to the genre and executed beautifully here.
- Win Limit & Loss Limit Controls: Built-in safeguards allow players to set caps, perfect for those managing budgets.
- Autoplay with Stop Conditions: Configure the game to pause automatically when reaching win/loss thresholds.
- High Hit Rate in Bonus Rounds: Anecdotally delivers more frequent and substantial wins in Free Spins than many peers.
Player Experience
“The animations in the bonus round are proper class. I stayed in just to see it again.” – Jon C.
“Familiar gameplay but seriously rewarding. Free spins paid out big.” – Chloe D.
“Hit x15 my stake three games in a row. Don’t know if it was luck or design, but I’m not complaining.” – Lewis H.
Lost Book Pros & Cons
Pros:
- Beautiful bonus animations that genuinely elevate the experience.
- Free Spins are generous and hit with decent frequency.
- High win potential, especially in Super Bonus rounds.
- Safety features like loss/win limits support responsible play.
- Solid return for mid-stakes players—feels fair and rewarding.
Cons:
- Base game feels flat—little excitement outside the Bonus Round.
- No innovation in gameplay mechanics.
- Generic theme execution without much character beyond the bonus visuals.
What’s Missing?
For all its visual polish, The Lost Book could benefit from:
- A Buy Bonus feature for players who want direct access to the best part of the game.
- Multipliers or layered wild mechanics to spice up the base game.
- A deeper narrative layer—something to connect the “Lost Book” to a character, quest, or mystery.
Still, what’s here works—and for fans of the format, that might be more than enough.
Final Conclusion: A Familiar Formula Done Right
The Lost Book isn’t reinventing the genre—but it doesn’t need to. Redstone Gaming have taken the essential DNA of the “Book of” slot and refined it to near-perfection, with standout bonus visuals and a surprising knack for regular, satisfying payouts.
While the base game might play it safe, the Free Spins truly deliver, with expanding symbols and a cinematic flair that make each bonus round feel like a small win in itself. Add in responsible gaming tools and a surprisingly high hit frequency in Super Bonuses, and you’ve got a game that offers value and entertainment in equal measure.
Final Rating: 8.6 / 10 – A highly polished Book-style slot that shines brightest in the bonus round—solid, safe, and seriously rewarding when it wants to be.
