Book of Magic Deluxe is Greentube’s entry in the expanding book slot genre, released in 2018. The game follows the structural template that Novomatic and its subsidiaries helped establish: a book symbol that functions simultaneously as wild and scatter, a free spins round triggered by three or more books, and a randomly selected expanding symbol that fills reels during the bonus. What distinguishes Book of Magic Deluxe from the many imitators is the quality of its base execution and the breadth of its betting range — minimums start at $0.05, opening the game to low-stakes players while the $100 ceiling covers high-volume sessions.

The game runs on 10 fixed paylines across a standard 5-reel grid. The magic book wild substitutes for all paying symbols in the usual fashion during base play, and its scatter function means it counts toward the trigger regardless of position — books anywhere on the reels contribute to the three-book threshold needed to start the bonus. The symbol set includes Egyptian-inflected imagery consistent with the magical tome aesthetic common to the subgenre.

Free Spins begin with a random expanding symbol selection: one symbol from the pay table is chosen and, whenever it appears during the bonus, it expands to cover its full reel. On a 10-payline structure, a reel fully covered by the expanding symbol contributes to a high density of paying lines across adjacent reels. The selection is made fresh on each bonus trigger, ensuring the feature does not consistently favour the same high-pay symbol across repeated sessions.

Book of Magic Deluxe returns 95.1% RTP at high volatility, with a maximum win of 5,000x the bet. No Bonus Buy is available.

Book of Magic Deluxe executes the book slot formula with the reliability that Greentube brings to its core genre. The high volatility and 5,000x ceiling make the expanding symbol mechanic meaningful, and the low minimum bet democratises access to that ceiling. A competent and well-regarded representative of the format.
