Play Book of Cleo Slot Game

Cleopatra-themed slots aren't exactly in short supply, but Tom Horn Gaming's Book of Cleo wants to stand out by adding a few mechanics to the classic "Book of..." formula. While the slot doesn't stray far from the usual Egyptian tropes — golden artefacts, hieroglyphs, and, of course, Cleopatra herself — it introduces Shatter Mode, which brings cascading wins and increasing multipliers into the mix. The visuals are polished, the soundtrack is suitably grand, and the gameplay has a familiar yet slightly fresh take on an often-explored theme.

The game plays out on a 5x3 grid with 9 paylines, a slightly unusual number compared to the more common 10 or 20 found in other Book-style slots. The Book symbol doubles as both the Wild and Scatter, helping to complete wins while also triggering the Free Spins round when at least three appear. The minimum bet is 0.10, making it accessible for different bankrolls.

Tom Horn Gaming has an interesting catalogue, often taking classic slot ideas and giving them their own twist. Other notable releases from the developer include 243 Crystal Fruits, a slot that reimagines fruit machines with expanding reels, and The Secret of Ba, which shares some similarities with Book of Cleo but follows a more traditional path.

The symbol selection sticks closely to the Egyptian theme, with Cleopatra as the highest-paying symbol, followed by ancient relics. The lower-tier symbols are classic A-10 royals. A complete breakdown of the symbols is given in the table below:

Apart from the symbols above, there is also one special symbol to account for - the book. In Book of Cleo, the Book symbol plays a dual role, acting as both a wild — substituting for all other symbols — and a scatter, responsible for triggering Free Spins.

Shatter Mode

Book of Cleo’s Shatter Mode brings cascading wins into the mix. Whenever a winning combination lands, the winning symbols shatter and disappear, allowing new symbols to fall into place. This can continue up to four consecutive times, with each shatter increasing the win multiplier, capped at x4. The feature resets once no new wins are formed.

Free Spins Feature

Landing three or more Book symbols triggers the Free Spins round, awarding 10 free spins. Before the feature begins, one symbol is randomly chosen as a special expanding symbol. This symbol expands to cover the entire reel whenever it appears, potentially leading to bigger payouts. Free Spins can retrigger if at least three Book symbols land again during the round.

Book of Cleo blends the familiar "Book of" format with cascading wins and multipliers, making it a mix of traditional and modern mechanics. If you enjoy this style, you might also want to check out Book of Ra Deluxe, which sticks to a more classic approach, or Book of Aladdin, which adds an Arabian Nights twist to the genre. All the titles are available at Heart Bingo.
