Book Of Aladdin Slot Review
A crescent moon hangs over a violet courtyard, bronze urns flickering at the foot of purple pillars while a domed palace glows in the distance. Inside that painting, Tom Horn Gaming have built a book slot that is harder to get into than almost any of its kind, because the book itself can only land on three of the five reels. Book Of Aladdin is a 5×3 game across nine winlines, running at high volatility with an RTP of 95.97%.
Two things carry the game: a shatter-and-multiplier chain in the base game, and a free spins round with an expanding symbol. The book itself does double duty as wild and scatter, which is the oldest trick in this particular library of spells. The studio have been here before with the Aladdin-themed 3 Pots of Aladdin, and titles like Giza’s Portals round out the same corner of their catalogue.
Whether this one earns a rub of the lamp is the question the reels have to answer.
Reels, Winline and the Book
The game runs five reels and three rows, with wins formed across nine fixed winlines. You choose your total bet before spinning, and the reels hold ten symbols in all. Spinning can be done one press at a time or through Autoplay, which runs the reels automatically at your chosen bet and line count, and stops on its own whenever free spins trigger. On mobile, the Autoplay controls sit inside the options menu rather than on the main screen.
The book is the slot’s one special symbol, and it carries two jobs at once:
- Wild – substitutes for every other symbol in the game
- Scatter – three of them trigger the free spins round
- Restricted to reels one, three and five – it can’t land anywhere else
That reel restriction is worth pausing on. A wild-and-scatter that only appears on three of the five reels is a rarer guest than its dual role suggests, and it shapes both the base game and the bonus trigger in ways that matter later.
The Paying Symbols
The paying symbols split into character highs and card royals, and the top of the ladder is steep. The values below are multiples of the line bet:
- Red/white turbaned King – 2 pays 1x, 3 pays 10x, 4 pays 100x, 5 pays 500x
- Woman – 2 pays 0.5x, 3 pays 4x, 4 pays 40x, 5 pays 200x
- Warrior or green-turbaned man – 2 pays 0.5x, 3 pays 3x, 4 pays 10x, 5 pays 75x
- A or K – 3 pays 0.5x, 4 pays 4x, 5 pays 15x
- Q, J or 10 – 3 pays 0.5x, 4 pays 2.5x, 5 pays 10x
Four of the character symbols pay for two of a kind, with the King returning 1x and the other three 0.5x. Five royals, by contrast, barely clear a tenth of the King’s top prize. This is a paytable built around its top two rows.
There’s a wider gap inside the character tier, too. The King pays five times what the woman does at the top of the ladder, and almost seven times the warrior pair, so a single substitution by the book into a near-miss King line changes the payout considerably more than the same substitution further down. With the book only landing on three reels, those substitutions are the base game’s main source of bigger line wins.
SHATTER Mode
Every base game win sets off the SHATTER mechanic, which runs on a simple loop:
- A winning combination lands and pays out
- The winning symbols explode and new symbols drop into their places
- If the new symbols form another win, that pays too, and the process repeats
- The chain ends either when no new win forms or after four shatters
Each new shatter in the chain increases the win multiplier, so a sequence that runs the full distance reaches 4x. The multiplier resets once the chain ends, so the base game’s rhythm is short bursts of escalating wins rather than one long build.
Four steps sounds modest, but the effect compounds. A chain that runs the full distance pays its later wins at a higher multiplier than its earlier ones, which is where a nine-line game finds room for a meaningful base game payout. The mechanic also runs during free spins, with the same four-step cap.
Free Spins and the Expanding Symbol
Triggering the Round
Three books are the only trigger, and they award ten free spins. Because the book is limited to reels one, three and five, that’s the full set of positions it can occupy – three books means one on each of its available reels. There’s no shortcut or random entry; the scatter combination is the door, and it’s a narrow one.
The round is retriggerable. Landing the same three-book combination inside free spins adds another ten spins on top of whatever remains, with no stated cap on how many times that can happen.
The Special Expanding Symbol
At the start of the round, a special expanding symbol is chosen at random. It works like this:
- One symbol is selected at random when the round begins
- Whenever enough of that symbol land to form a win, it expands to cover its entire reel
- Expanded symbols don’t need to sit on adjacent reels or follow the usual winline order to pay
That third point is the generous one. In the classic book formula the expanding symbol pays on winlines like everything else; here, landing the symbols is enough on its own. Fill three or more reels with an expanded top-tier symbol and the pays stack up quickly.
The SHATTER multiplier also runs during the round, reaching up to 4x there as well. Combined with retriggerable spins and the scattered expanding pays, that’s where the game’s real weight sits.
Our Honest Verdict
Overall Rating: 7.1/10
Long stretches of Book Of Aladdin are spent sitting in that painted courtyard, listening to small shatter chains tick over while the palace glows patiently behind the reels. The reason to be here is the round behind the narrow door: an expanding symbol that pays wherever it lands, with a 4x multiplier stacked on top.
That scattered expanding pay is the game’s best idea, and it’s genuinely more generous than the classic book formula. The cost is the door itself. With the book confined to three reels, the trigger is rarer than in most book slots, and high volatility means the quiet stretches in between can run long.
This is one for book-slot traditionalists who don’t mind earning the bonus and will enjoy the artwork while they wait. Anyone after elaborate bonus ladders or enormous ceilings will find it sparse. The palace windows stay warm and lit; the wishes are simply rationed.
