Book of Kings 2: High-Volatility Egyptian Adventure by Playtech

Quick take: Best for players who want high-variance sessions with a proven book-slot format — the Day/Night dual-mode system adds a fresh twist on a familiar structure.

Book of Kings 2 is a 5-reel, 3-row slot developed by Rarestone Gaming and published by Playtech. It follows Jane Jones, an adventure heroine hunting relics in an Egyptian setting, and builds a dual-mode structure on top of the classic expanding-symbol book mechanic. The 96.5% RTP sits above the 96% industry average. High volatility means wins land less often, but the 4,000x max win multiplier makes those sessions worthwhile for patient players. The book of kings 2 free play demo here on Slottomat lets you road-test both game modes without any risk.

Core Stats at a Glance

The game runs on 10 fixed paylines across a standard 5×3 grid. Stakes range from $0.10 to $350 per spin, covering a wide range of budgets. At 96.5% RTP, the theoretical return is solid for a high-volatility title — most slots of this volatility cluster around 95–96%. The max win of 4,000x your stake is achievable through the expanding symbol mechanics in the bonus rounds.

Symbols include royal card icons (9 through A) and premium Egyptian artifacts: ankhs, scarabs, golden rings, and Jane Jones herself as the top-paying regular symbol. Two separate Book symbols — the Day Book and the Night Book — serve as the key feature triggers.

Day Mode and Night Mode

The standout mechanic in Book of Kings 2 is the shift between Day Mode and Night Mode. The game starts in Day Mode. Night Mode activates randomly during base play, awarding at least three Night Free Games spins before the reels return to Day Mode. Each mode has its own Book scatter and its own free games feature with different trigger thresholds.

Day Free Games Feature

Land three or more Day Book scatters anywhere on the reels to trigger the Day Free Games. You receive 10 free spins regardless of how many scatters landed. Before the round starts, one symbol is randomly selected to become the Special Expanding Symbol for the entire feature. Whenever that symbol appears in sufficient quantity — premium symbols need at least 2 matching positions, royals need at least 3 — it expands to fill all three positions on its reel. Crucially, the expanding symbol does not need to appear on adjacent reels to form a win, which makes the potential payouts significantly larger than in most book-style slots. Three or more Day Book scatters landing during the feature retrigger the bonus and add another 10 spins.

Night Free Games Feature

Night Mode uses a lower trigger threshold. Two Night Book scatters award 5 free spins; three or more award 10. The same expanding symbol mechanic applies — a random symbol is chosen and the same adjacency-free expansion rule holds. Landing three or more Night Books during the feature adds another 10 spins to your total.

Gamble Feature and Bonus Buy

After any winning spin, an optional Gamble Feature lets you risk the win by guessing a hidden card's color (doubles the win) or suit (quadruples it). A wrong guess forfeits the original win entirely — use it sparingly on smaller amounts. For players who prefer to go straight to the action, a Bonus Buy option is available, letting you purchase direct access to the bonus round at a set cost multiplier.

Try Book of Kings 2 Free Play on Slottomat

The book of kings 2 free play demo on Slottomat requires no download and no account. You get a virtual balance that resets freely, so you can test both Day and Night mode features as many times as you like. High-volatility games like this one particularly benefit from demo play — you can experience the full range of session outcomes, from dry spells to expanding symbol wins, before committing real money anywhere.

Graphics, Sound, and Mobile

The visual design blends warm desert tones in Day Mode with cooler, moonlit tones in Night Mode — a subtle shift that reinforces the dual-mode theme without being distracting. Animations are clean and the expanding symbol sequence is satisfying without slowing the pace. Built on HTML5, the game runs natively in mobile browsers on iOS and Android. Touch controls work cleanly, and the interface scales well from phone to tablet to desktop.

Playing High Volatility Well

• Size your bankroll for dry spells. High-volatility games can run 50–100 spins between meaningful wins. A session budget of at least 100× your chosen stake gives the variance room to breathe.
• Use the free demo first. The expanding symbol mechanic feels very different depending on which symbol gets selected. Running the demo lets you see this variance in practice.
• The 4,000x cap matters. That ceiling is reached when a top-paying symbol like Jane Jones expands across multiple reels simultaneously during free games. It is rare but is the target the entire bonus structure is built around.
• Bonus Buy decision. The feature is infrequent in base play by design. If your budget is limited, base game may exhaust it before a trigger. Bonus Buy trades a higher upfront cost for guaranteed entry.

More from Playtech

If the book-slot format appeals to you, Age of the Gods Book of Oracle is the closest match in the Playtech catalog — same expanding symbol structure, Playtech's own mythology brand, and a linked jackpot on top. For a different pace, the mythology-heavy Age of the Gods and its spinoff Age of the Gods Norse Legends deliver branded progressive jackpots alongside solid base mechanics. If you want something faster and more volatile without the book format, Hot Gems Xtreme and Buffalo Blitz offer Playtech's high-energy style on very different themes.

Final Verdict

Book of Kings 2 earns its place in the book-slot genre by adding genuine mechanical depth through the Day/Night dual-mode system. The 96.5% RTP and verified 4,000x max win are legitimate selling points, not marketing inflations. High volatility is real — patience and a suitable bankroll are required.
