Don your best explorer gear and delve into ancient catacombs on the cult slot from Novomatic (Greentube). While the origins go back to 2005 when Novomatic released the original Book Of Ra slot, its Deluxe sibling is to this day the most popular sequel which was launched in 2008 with improved graphics and more pay lines. Inherent to the slot is the high volatility and a free spins round that can lead to wins of up to 5,000 times yours stake.
Book of Ra is the mother all slots with special expanding symbols in the free spins and has been copied and cloned ad absurdum by virtually every other game provider. Novomatic didn’t stop either and has meanwhile about a dozen sequels in land-based and online casinos. Take your pick from Deluxe 6, Magic, Mystic Fortunes, Jackpot, Temple of Gold and more.
Book of Ra Deluxe is a video slot with five reels, three rows and 10 variable pay lines. Wins are awarded for two to five matching symbols on a line from left to right only. You expedition into the ancient catacombs on desktop or mobile will cost you 0.10 to a gigantic 400 credits per spin. The game is highly volatile with an RTP of 95.10%.
As the name Deluxe indicates, the sequel is actually an upgrade to the original and it clearly shows in the graphics. A sunset scene with ancient Egyptian pyramids sits on top of the reels while a hieroglyph-covered wall is the background to the usual simplistic game window. The soundtrack is now richer and resembles sounds from a real casino mixed together with a typical Arabian tune.
The pay symbols start at the low end with the usual card royals from 10 to A, paying 10x to 15x your stake for a single five of a king. They are followed by blue scarabs, the Egyptian winged goddess Isis, the bust of Tutankhamun and the explorer, awarding wins from 75x to 500x your bet when five land on a line.
The famed book is the wild and scatter symbol, substituting for all regular pay symbols. It will also 2x, 20x and 200x your total bet when three, four or five land on a spin.
Hit minimum three book scatters anywhere on the reels in one spin to trigger 10 free spins, which can be re-triggered indefinitely. Before the bonus round starts, one of the nine regular pay symbols is selected as the special symbol. When sufficient land on a free spin, they will expand vertically to cover the entire reel and award wins for all pay lines, even when they are not adjacent. It will need minimum three low-paying symbols or minimum two premium symbols anywhere on the screen to see them expand and award a win. The wins from the expanding symbol are paid on top of any potential line wins.
This is of course the moment where the slot can produce the maximum win on a single spin. The selected special symbol has to be the explorer and if five land in view across the reels, they will expand to pay 10 times the single line win for a five-of-a-kind, which is 500x the stake, resulting in a total of 5,000x your stake.
Well, I don’t think Book of Ra Deluxe needs a lot of positive reviews or praise as the immense popularity even more than a decade after its release speaks louder than any written words. The slot is highly volatile as you can expect from Novomatic while the maximum win potential seems to hit quite regularly as the mass of screenshots in forums suggest.
