Amuns Book HD Deluxe Slot by Zeusplay

Zeusplay's Amun's Book series has been iterating on the "Book of" formula for years. The HD Deluxe version, released in January 2025, is the strongest entry yet. Not because of a new grid layout or exotic mechanic, but because of one simple idea: every retrigger during free spins adds another expanding symbol.

Multi-Symbol Expansion

Three or more Book of Amun symbols anywhere trigger 8 free spins. At the start, one symbol is randomly selected as the special expanding symbol. When it lands on a reel and contributes to a win, it expands to fill all three positions on that reel. Standard Book of mechanics so far.

The twist: land 3+ books during free spins and you get 8 more spins plus a second expanding symbol. Retrigger again, a third symbol joins. This stacks up to 9 special symbols - every regular symbol in the game can become an expander simultaneously. With unlimited retriggers, a deep enough free spin session transforms the entire reel set into expanding symbol territory.

Is that realistic? Rarely. Getting past 2-3 expanding symbols takes extraordinary luck with book landings. But the ceiling is real - 8,480x max win, and the path to get there is mathematically sound.

The Paytable Deserves Attention

The explorer tops the chart at 500x bet for five of a kind. That's double what the HD 6 version pays for the same symbol across 5 reels. The Book of Amun matches it at 500x, making both the wild and the premium symbol equally valuable. Sphinx sits at 160x, while scarab and Anubis share 60x for five.

Card symbols split into two groups: A and K pay 12x for five, Q through 10 pay 8x. These low pays seem irrelevant until a card symbol becomes the expanding special. With full reel coverage and any-position payline evaluation, even a 10 symbol expanding across three reels generates meaningful returns.

Compared to Other Book Games

Book of Dead by Play'n GO - the genre standard - offers 96.21% RTP with a single expanding symbol and 5,000x max win. Amuns Book HD Deluxe beats it on both counts: 96.24% RTP and 8,480x max win. The multi-symbol expansion gives it a theoretical edge that Rich Wilde's version doesn't have.

Against Zeusplay's own HD 6 variant: that game adds a sixth reel but limits you to one expanding symbol. The Deluxe keeps 5 reels but unlocks up to 9 expanders. More expanding symbols on fewer reels produces higher peak wins. Different approaches, but the Deluxe has the higher ceiling.

The Catch

Medium-high volatility means the base game is thin. Ten paylines on a 5x3 grid with a steep paytable gap between premium and card symbols means most spins return nothing or near-nothing. You're playing for the free spins trigger, and specifically for retriggers within free spins. Without at least one retrigger, the feature pays modestly.

The dark, atmospheric Egyptian visuals - nighttime pyramids, crescent moon, stone tablet reel frames - look better than the sandy daytime aesthetic of the HD 6 version. It's a small thing, but it gives the Deluxe a more polished feel.
