Adventure calls on the bravest explorers on the epic cult slot from Novomatic (Greentube). Book of Ra Deluxe 10 is another addition to the immensely popular slot series that debuted in 2005 and has grown to over a dozen titles. Core to their success is the expanding special symbol in the free spins that can deliver huge mega wins. This creation will spoil us with two reel sets, stacked symbols, transferring wilds and a free spins round.
Book of Ra is a video slot with a dual reel set, featuring a 5×4 grid with 25 fixed pay lines and a 5×12 grid with 75 fixed pay lines. Each grid it a standalone game window. The ancient book opens again on desktop or mobile from 0.20 to 40 credits per spin. The game has medium volatility (2/5) with an RTP of 95.02%, which is in line with all other slots in the series.
Fans of Book of Ra slot will find a familiar scene when they load the game for the first time. It is back to ancient Egypt although this the time the screen covered to a large extent by the two game windows. Nevertheless, the mummy, scarabs and the fabled explorer are returning for the next episode in the Ra saga.
The pay symbols start at the low end with the card royals from 10 through to A, awarding 1x your bet for a single five of a kind. They are followed by blue scarabs, the Egyptian winged goddess Isis, the bust of Tutankhamun and the explorer. Hit five on a line to win 2x to 5x your stake. All symbols can appear in stacks on any of the reel sets.
New is the golden Bastet coin as the wild symbol, substituting for all regular pay symbols. The fabled book still acts as a scatter, appearing on reels one, three and five of each reel set only.
With the new set-up, the developer also added some more features to, well, justify the use of the extra reels. We have seen similar layouts coming from Scientific Games studios such as Barcrest or Bally, but this is the first encounter on a Novomatic (Greentube) slot.
If you ever played such games from the other providers, then you surely must have experienced the Transferring Wilds feature. Any full stack of Bastet coin wilds landing on reel set one will be mirrored in full height on the same reel on the second grid, providing extra potential to score a win.
The eponymous Book scatter is still at the centre of the gameplay and will trigger 8, 12 and 20 Free Spins respectively when three, four or five and more land on a spin. Plus you will get a coin payout of 2x, 5x and 20x your total bet respectively. Before the Free Spins begin, one regular pay symbol is randomly chosen to become the Special Expanding symbol for the entire feature. Special Expanding symbols will cover entire reels when they land on reel set one, paying out even on non-adjacent positions. These positions are then copied to the second reel set followed by another win evaluation.
If you are looking for an extra thrill, then the Gamble function might be just right for you. Simply click on the button after scoring a win and the game will lead you to a second screen where you can choose between black or red for the next card to be drawn. Guess the correct colour to double your win, which you can repeat until the winning amount reaches the maximum of 500 times your current bet.
Well, the hat is legendary and the book is the stuff of dreams. The Book of Ra series has mesmerized players for more than a decade, making the explorer a cult figure and expanding symbol mechanic one of the most copied features on online slots. Book of Ra Deluxe 10 is carrying the legacy into the next years with a novel reel set that is bound to deliver mega wins just like its siblings. Well worth to give it not just a few spins when the slot is released.
