Playing Book of Raider - First Impressions
Book of Raider is a 5-reel slot from Gong Gaming Technologies, released on 28th March 2022 and distributed exclusively through Games Global (formerly Microgaming). It sits within the Royal League series, which tells you straight away there is a shared jackpot element tying it to other titles in that range. The theme leans heavily on ancient exploration and treasure hunting, and visually it does enough to hold your attention during longer sessions.
I sat down with this one expecting a fairly standard book-style slot, and honestly that is more or less what you get. The base game can feel quiet for stretches, which is typical for this volatility bracket. RTP comes in at 95.75%, which is below what I would usually prefer but not unusual for slots linked to a progressive jackpot network.

Book of Raider Symbols and Paytable
The paytable follows the classic book-slot structure. You have low-value card royals filling up the reels most of the time, with themed premium symbols depicting adventure and exploration imagery. The Book symbol itself acts as both the Wild and the Scatter, which keeps things simple. Landing three or more Books anywhere on the reels triggers the free spins round and also substitutes for other symbols to complete winning lines.

How Book of Raider Bonus Rounds Work
The main bonus in Book of Raider is a free spins feature triggered by landing three or more Book scatter symbols. Before the round begins, a random symbol is selected to act as a special expanding symbol. When it appears during free spins, it can expand to cover entire reels, which is where the bigger payouts come from.
In my sessions, the bonus triggered at a fairly average rate for a high-volatility book slot. You can go through dry patches of 80 to 120 spins without seeing it, then get a cluster of triggers. The expanding symbol mechanic is the real make-or-break moment. If the game picks a premium symbol, the round can deliver nicely. If it lands on a low-value royal, you are generally looking at a disappointing return.
Being part of the Royal League series also means there is a jackpot layer sitting on top. This is a shared progressive pot across multiple Royal League titles from Gong Gaming, adding an extra incentive for players who like chasing larger pooled prizes.
Book of Raider RTP, Volatility and Win Potential
The RTP on Book of Raider is listed at 95.75%. That is on the lower side compared to many UK-facing slots, and part of the reason is the jackpot contribution baked into each spin. Volatility feels high in practice. Base game wins are modest and infrequent, with the real value locked behind the free spins feature and the progressive jackpot chance.

Final Verdict on Book of Raider
Book of Raider does not reinvent the wheel. If you have played any book-style slot before, you already know how this one plays out. Gong Gaming have kept things straightforward, which is fine, but the below-average RTP makes it harder to recommend for extended grinding sessions. The Royal League jackpot connection is the distinguishing feature here and the main reason to pick this over other book slots.
For UK players who enjoy high-volatility slots with a progressive jackpot element, it is worth a look. Just go in with realistic expectations about the base game payout frequency and manage your bankroll accordingly.
