Book of Arcane 100 is a fantasy-themed video slot developed by Just Slots, released on 2025-05-29. The game immerses players in a mystical world of magic where two powerful sorcerers clash with ice and fire for domination, while the player takes the role of a student unlocking forgotten magic sealed within the Wild Book.

Design and Graphics
The visual design of Book of Arcane 100 transports players to a enchanting terrace overlooking a magical library, where books dramatically fly from shelves amid a grand castle backdrop.

The game’s aesthetic is polished and thematic, with high-quality animations for symbol expansions and wins, ensuring smooth performance across desktops, tablets, and mobiles.

Symbols are richly detailed to fit the sorcery theme. Low-paying royals (J, Q, K, A) offer subdued metallic designs, paying 4x to 5x the bet for five of a kind. Medium-paying icons include a glowing scroll, ornate ring, and wizard’s hat, delivering 10x to 15x the bet for five symbols. High-paying sorcerers—green, blue, and red—command attention with dynamic elemental effects, rewarding 50x to 100x the bet for five in a row. The Wild Book stands out as a golden tome pulsing with energy, serving as the key trigger for bonuses. Overall, the graphics are crisp, atmospheric, and cohesive, enhancing the fantasy narrative without overwhelming the core gameplay.
Gameplay Mechanics
Book of Arcane 100 employs a straightforward 5 reels, 3 rows, and 10 paylines configuration. Wins form by landing three or more matching symbols on adjacent reels starting from the leftmost reel. Bets range from a minimum of €0.10 to a maximum of €100, accommodating casual players and high rollers alike. The base game flows rhythmically with a 27% hit frequency, where the Wild Book substitutes for all paying symbols to complete combinations.
A standout mechanic is the random Expanding Symbols feature in the base game. Before reels settle, a special symbol and multiplier from 1x to 100x are selected. This symbol expands to cover reels, paying across all 10 paylines even if non-adjacent, providing frequent mid-sized wins amid the mid-high volatility. The interface is intuitive, with clear payline visuals and auto-spin options, ensuring accessible yet engaging spins in this classic Book-style setup.
| Symbol Type | 5-of-a-Kind Payout (x Bet) |
|---|---|
| J, Q, K, A (Low) | 4x – 5x |
| Scroll, Ring, Hat (Medium) | 10x – 15x |
| Green/Blue/Red Sorcerer (High) | 50x – 100x |
Bonus Features
The bonus arsenal centers on the Wild Book, which not only substitutes but triggers the marquee Free Spins round. Landing 3, 4, or 5 Wilds awards 10 Free Spins, with a randomly selected Expanding Symbol and multiplier applied: random for 3 Wilds, minimum 2x for 4 Wilds, and 10x or higher for 5 Wilds. During Free Spins, the chosen symbol expands fully on winning lines, paying anywhere on the reels with the attached multiplier, amplifying payouts significantly.

Retriggering occurs with 2, 3, 4, or 5 Wilds adding 3, 10, 15, or 20 extra spins respectively, plus an additional random multiplier stacked onto the current one. The Free Spins Gamble adds excitement pre-round: three wheels offer upgrades—Expanding Symbol Wheel (tiers up symbol), Multiplier Wheel (tiers up multiplier), or combined wheel for max rewards. Failure forfeits the bonus entirely, appealing to risk-tolerant players.
Base-game Expanding Symbols activate randomly per spin, selecting a symbol and 1x-100x multiplier that expands and pays across all lines. A Feature Buy option bypasses the grind:
| Buy Option | Cost (x Bet) | Wilds Triggered |
|---|---|---|
| 3 Wilds | 80x | 10 Free Spins (random multiplier) |
| 4 Wilds | 250x | 10 Free Spins (2x+ multiplier) |
| 5 Wilds | 1050x | 10 Free Spins (10x+ multiplier) |
These mechanics synergize for explosive potential, with retriggers and stacked multipliers driving the 100,000x max win.
Betting Options and Payouts
Bets span €0.10 to €100, supporting flexible playstyles. The default RTP 96.36% is competitive, though variants at 94.33% and 92.42% exist. Mid-high volatility (bordering high) pairs with a 27% hit frequency, favoring infrequent but substantial wins, culminating in the standout 100,000x max win—the highest from Just Slots to date. Payouts scale generously via high symbols and features, with Free Spins multipliers up to 100x or more through retriggers fueling big hits.

Conclusion
Book of Arcane 100 excels in its thematic cohesion, stunning visuals, and potent Free Spins with expanding symbols, retriggers, and gamble wheels, delivering a classic Book experience elevated by massive 100,000x max win potential and base-game random expansions. Strengths include the 96.36% RTP, broad bet range, and Feature Buy accessibility, ideal for high-volatility enthusiasts. Weaknesses lie in its relative simplicity, lacking diverse base-game layers beyond random features, and gamble risk that may frustrate conservative players. Players can test the slot risk-free using the built-in demo available on this page. Overall, it’s a compelling entry from Just Slots for magic-themed slot fans seeking high-reward thrills.
