The Book Of Ra Deluxe is an upgrade to the original Book Of Ra slot from Novomatic. It's
essentially identical in most respects - the graphics have been tweaked to make them a bit more
21st century and an extra payline has been added. That aside, it's the same game and still just
The feature in the Book Of Ra slot games is the same as in Lord Of The Ocean - 10 free spins with a randomly selected "expanding scatter" symbol. The frequency of retriggers is decent too and if yu can get a prolific expanding symbol and a couple of retriggers the rewards can be excellent. It's unusual to get less than 40x back from a Book Of Ra feature in any case (but it can happen!).
Most of the Novomatic slots are volatile, not just Book Of Ra. The Dolphins Pearl Deluxe slot game along with the closely related Lucky Ladys Charm can both knock out very long barren streaks but like Ra, both can pay handsomely in the feature round. If you don't like "volatile" but like Novomatic games then the best options are Beetle Mania Deluxe or Columbus Deluxe which give a bit more bang for your bucj but the trade-off is it's not often you hit a whopper like you can do on Book Of Ra Deluxe, Dolphins pearl or one of my other favorite Novomatic slot games, the excellent Katana (re-branded from Shogun in B&M casinos).
