Key Features β¨
The Book Mechanic: Free Spins and Expanding Symbols
The heart of Book of Odin, like its counterparts, lies in its free spins feature. Landing 3, 4, or 5 Book of Odin symbols awards 10 free spins. Before the free spins commence, a random symbol is chosen to become the special expanding symbol for the duration of the bonus round.
Special Expanding Symbol π
If enough of the special expanding symbols land on different reels during the free spins, they will expand to cover their entire respective reels, potentially leading to significant wins across all 10 paylines, even if they are not adjacent. These expanding symbols do not need to land on adjacent reels to form a win, as long as the minimum number for a win is present (e.g., three for low pays, two for high pays).
Free Spins Retrigger π
The free spins feature can be retriggered by landing three or more additional Book of Odin symbols during the bonus round. This awards another 10 free spins, prolonging the excitement and increasing the potential for massive payouts.
Buy Bonus Option β‘
For players eager to jump straight into the action, Book of Odin often includes a Buy Bonus option. This allows players to instantly trigger the free spins feature by paying a certain multiple of their current bet, typically around 100x.
Volatility and RTP π
Book of Odin is characterized by high volatility. This means that while wins may not occur as frequently, the potential for large payouts, particularly during the free spins feature with expanding symbols, is considerably higher.
