Book of Aztec — Game Overview
Book of Aztec is Amatic's most prominent online slot and the studio's entry in the widely-distributed 'Book' slot genre. The game uses a 5×3 layout with 10 paylines and an Aztec exploration theme — replacing the Egyptian archaeologist protagonist common in Novomatic titles with a character searching the ruins of pre-Columbian Mesoamerican civilisation. The expanding symbol free spins mechanic is structurally identical to the format established by Book of Ra.
The Book of Aztec symbol acts as both scatter and wild in the base game. In the free spins round — triggered by landing three or more Books on any position — one symbol is randomly selected before the spins begin. That chosen symbol becomes an expanding symbol: if it lands anywhere on a reel during free spins, it expands to fill the full height of that reel and pays as though present on all three rows. Three or more Books during the free round retrigger additional spins.
Amatic chose the Aztec theme as a deliberate differentiation strategy. While the Egyptian genre was dominated by Novomatic's own titles and Play'n GO's Book of Dead, the pre-Columbian setting was less crowded. The Aztec visual palette — gold pyramids, jade artefacts, feathered serpents, and jungle backgrounds — gives Book of Aztec a distinct look while operating within the same familiar mechanical framework that Book players already understand.
Book of Aztec is widely distributed in Central and Eastern European markets through Amatic's operator network. The game targets the established audience for Book-format slots who want an alternative theme without learning a new mechanic.

Verdict
Book of Aztec is a competent entry in the Book-format slot genre, offering a thematic alternative to the Egyptian-themed originals with Aztec imagery and archaeology motifs. The mechanic is functionally identical to Book of Ra and its descendants. At 95.30% RTP it is slightly below current online averages, but the familiar format makes it immediately accessible to players from the Book-style genre.
