Pragmatic Play's six-reel Egyptian slot uses expanding symbols in the bonus round, with 96.46% RTP and wins that come less often but run much bigger.

Book of Golden Sands: 729 ways to win. Book of Golden Sands is a six-reel, four-row slot with an Egyptian theme, released by Pragmatic Play in 2022. The game uses 729 ways to win, not paylines, so matching symbols can form a winning combination across different rows on each reel. Wild symbols land on reels two through six and carry random multipliers of 2x or 3x. The Scatter symbol, styled as a golden book, appears on all reels and triggers the Free Spins bonus round. High volatility means wins arrive less often but tend to be substantially larger.
Who enjoys long stretches between wins? The high volatility and bet range from NZ$0.20 to NZ$100 per spin suit players comfortable with longer dry spells in exchange for bigger payouts. The expanding symbol mechanic during Free Spins adds depth beyond standard reel games. Newer players or those who prefer frequent small wins may find the gaps between wins frustrating. The theme appeals to those drawn to Egyptian settings, though the gameplay matters more than the aesthetic.
What happens when free spins start? The Free Spins round defines how a session unfolds. Land three or more book symbols on different reels to trigger ten free spins, during which the game selects one random symbol to expand whenever three or more of it land on separate reels. That symbol stretches to fill entire positions on those reels, and the game tracks how many expanded instances build up per reel, growing up to ten. The more reels involved, the more winning combinations form. Retriggering free spins carries no limit.

You'll understand the sequence of every spin from bet to result and bonus trigger.
These payouts are in New Zealand dollars at a NZ$0.20 bet; matching three or more symbols of one kind creates a win.
How do expanding symbols work. Land 3 or more book scatters across different reels to start 10 free spins. One symbol is randomly chosen to expand vertically after each spin. When 3 or more of that symbol land on separate reels, it fills all positions on those reels. Collected expanded symbols grow on each reel, multiplying your winning ways up to 150.
Skip the wait and buy free spins. Buy your way into 10 free spins instantly for NZ$200 at the example top bet of NZ$2, or 100 times your stake at any bet level. The expanding symbol feature activates immediately with the same rules as the triggered round. This purchase carries an RTP of 96.38 percent.
What triggers your base game wins. The base game runs on a 6x4 grid with 729 ways to win left to right. Wild symbols land on reels 2 through 6 and apply a random 2x or 3x multiplier to your win. Book scatters appear on all reels, and the buy feature offers a direct path to the bonus round.

RTP is the average return calculated over millions of spins. Each RTP figure applies only to the condition listed: the standard game, or the specific bonus you buy. Your actual return on any session can differ widely.
Pay NZ$200 at your example top bet to trigger 10 free spins with an expanding symbol chosen at random. One symbol expands vertically across reels as it lands, collecting on top of each reel to build massive winning ways.
Book of Golden Sands bonus timing stays random. The bonus round arrives at random intervals. No player can predict when free spins will trigger, how often they'll come, or whether they'll appear in a session at all.
Long-term average versus your spin. Whether you win or lose in any single session depends on random outcomes, not on your choices or the slot's history. The RTP figure shows long-term results across millions of spins, not what happens to you today.
Maximum win: the rare exception. A maximum win of NZ$1,000,000 is a ceiling, reached extremely rarely. Most sessions end far below this figure. Chasing the maximum or expecting it would misread how the slot works.
We explain what this slot does, how it pays, and what stays unpredictable.
Plan Your Session Cost. Set a budget for your session before you place your first bet. Decide how much you can comfortably afford to lose, and stick to that amount regardless of how the reels land.
When to Step Away. Decide your stopping point in advance, including after a win. Walk away when that moment arrives, even if the game feels ready for one more spin.
Limits Protect Your Budget. Use your account's deposit limits and loss limits to enforce your choices automatically. These tools keep your spending inside the boundaries you set.
Book of Golden Sands Can Wait. Take a break or use self-exclusion if the game stops bringing you joy. Your account tools let you pause play whenever you need space.
