Book Of Aztec King Slot Review
A stepped golden pyramid glows behind the reels at dusk, jewel studs catching the last of a pink-orange sky, while a green-faced warrior in a full feathered headdress stands watch at the frame’s edge. Book Of Aztec King’s real change to the Book formula isn’t the jungle swap, it’s that the two royal symbols pay from just two of a kind, which quietly rewires how every expansion on the grid gets valued. Pragmatic Play build it on a 5×3 grid with an RTP of 96.50% and medium volatility, with stakes from 0.10 to 250 per spin.
It sits in a busy corner of the studio’s catalogue, beside John Hunter and the Book of Tut and Book of Golden Sands, with Book of Kingdoms a close cousin. The jungle suits it better than most.
Symbols and Pays
All symbols pay from left to right on adjacent reels starting from the leftmost reel, and all wins are multiplied by the bet per line. Only the highest win is paid per line, with wins across multiple lines added together. Values are coins:
- Aztec King: 2, 20, 200 or 1,000 coins for two, three, four or five
- Aztec Queen: 1, 8, 80 or 400 coins
- Leopard: 1, 6, 20 or 150 coins
- Toucan: 1, 6, 20 or 150 coins
- A: 1, 8 or 30 coins for three, four or five
- K: 1, 8 or 30 coins
- Q: 1, 5 or 20 coins
- J: 1, 5 or 20 coins
- 10: 1, 5 or 20 coins
The paytable is top-heavy, weighted hard towards the two royal figures at the top. The King and Queen are the only symbols that pay for a two-of-a-kind, which matters more than it sounds on a game where expansions can drop matching symbols onto scattered reels. The King alone carries the table’s only four-figure payout.
The mid tier tells its own story. Leopard and toucan pay identically, and the five royals below them compress into two bands: A and K together, then Q, J and 10 sharing the bottom row. Three of any royal returns a single coin, which keeps the base game lean between feature hits and puts the emphasis squarely on the expanding symbols.
The two-of-a-kind pays also do quiet structural work. Because the King and Queen start paying from just two symbols, an expansion doesn’t need a full five-of-a-kind to matter, and a pair sitting anywhere on the grid can turn into something once a reel fills. The bottom of the table exists to be expanded, not collected.
The Book is both wild and scatter, and it doesn’t need a section of its own: it substitutes for every symbol, and as a scatter it pays 2x, 20x or 200x the total bet for three, four or five anywhere on the screen. Three or more also open the free spins round, covered below. It’s the only symbol on the grid with two jobs, and both of them point at the same feature.
The Mystery Symbol
Every spin, one symbol is selected at random as the mystery symbol, shown in a panel above the reels. If enough of them land to form a win, the symbol expands vertically after regular pays to cover all three positions on its reel. The panel rotates through toucans, royals and the King himself from spin to spin, so the pick changes constantly.
Once expanded, the symbol pays wherever it sits, not just on adjacent reels. Expansion only happens when a win is already there, so a reel full of a dead symbol stays dead. That’s the whole base game hook, and it cycles fast.
The order of events matters. Regular paying symbols settle first, then any qualifying mystery symbol expands, then the expanded pays land. A spin can therefore lose on its line wins and still pay through the expansion, which is where most of the base game’s bigger moments come from.
Which symbol gets picked also shapes the spin’s ceiling. A mystery royal is a near-guaranteed small return, since three of a kind pays from anywhere once the reel fills. A mystery King or Queen is rarer and worth far more, with the two-of-a-kind pays making partial fills pay too. The panel makes every spin a small reveal before the reels stop.
Free Spins
Three or more Books anywhere on the screen award 10 free spins. Before the round begins, two special mystery expanding symbols are selected at random, doubling the number of expansion candidates the base game carries. The round then runs on the same principle, with more ways for it to fire:
- Two special symbols, chosen at random before the first spin
- Both expand to fill their reels after regular symbols pay out, one after the other
- Expanded specials pay on all reels, even on non-adjacent positions
- Three or more Books during the round retrigger 10 more spins
The expansions resolve in sequence rather than together. The first special expands and pays, then the second does the same, so a spin carrying both can stack two separate expanded payouts on top of its line wins. Either can be the King, which is the round’s best draw.
Expansion still only happens when enough symbols for a win are present, so the feature doesn’t hand out screen-fills for free. Special reels are in play during the round, a separate strip from the base game’s.
Retriggers
Three or more Books during the round award 10 more spins, keeping the currently selected special symbols rather than drawing new ones. There is no limit to the number of retriggers. A lucky round can therefore run far past its starting ten spins with the same two symbols doing the work throughout.
Free spins wins are added to payline wins, and the round’s total is paid once it completes. In a retriggered round that total covers the whole cycle, spins and all.
Our Honest Verdict
Overall Rating: 7.2/10
Most of a session here is spent watching that little panel above the reels, waiting to see whether this spin’s mystery symbol is a dead royal or the King. That’s the reason to pick it over the dozen other Book games: the expansion runs every single spin, not just in the bonus, and the pyramid glow gives it better scenery than the desert ever did.
The free spins round is the strongest part of the build. Two expanding specials instead of the usual one roughly doubles the chance a spin fills the screen, they pay on non-adjacent positions, and retriggers don’t stop. The weakness is what sits between the expansions: three royals pay a single coin, so the base game can go very quiet, and the game publishes no maximum win figure at all.
It’s for players who already like the Book format and want it wrapped in jungle rather than sand, and who don’t mind waiting on the temple steps for the good rounds. Anyone after layered features will find the vines thin. For Book fans, though, this one wears its feathers well.
