How to play

The rules of playing any slot aren’t difficult. And this one also will be easy to access. That’s the guide for playing it:

  • Log in at the casino or get registered
  • Open The Book of Amaterasu and select the bet of 0.2–20 credits
  • Start playing in a standard or autoplay mode
  • Buy a bonus feature if you want to trigger it at once

Here, you will find 10 lines that are fixed. Regarding bonuses, they also take place and include free spins with expanding symbols, so you can launch them naturally or by buying the feature.

The Book of Amaterasu RTP and Volatility

8.1 

Though the game has nice options, its RTP of 95% is not as high as you may want.

Unfortunately, the supplier selected a really low RTP that is not below average, but not good enough as well. With a payout rate of 95%, the hopping 5% accounts for a house edge, so that should be considered. Volatility is high with a hit rate of 28.9%. According to this, you should plan your budget carefully, keeping in mind that this slot won’t pay often. Payouts will be rare but big.

Theme

8.8 

The theme of the title is truly Asian and relaxing. You will find yourself in the mountains with purple trees and blossoming sakura branches. Asian music is also nice. The symbols are cute and perfectly match this trip to the magic land. When the reels rotate, they sound like water flowing down the mountain. Flowers and items of Japanese culture are displayed on these 5 reels.

To find out what the goddess of the Sun has prepared for you, land symbols of the paytable on the 10 paylines and receive payouts according to their values. Low-paying symbols should land at least 3 times, and the mask or more valuable symbols can appear only twice on a payline for players to get paid for that.

Overall Rating

8.5

This relaxing slot deserves the recognition of the gambling society for its pleasing theme and immersive atmosphere that brings fascinating Japanese lands to life. Bonus options are pretty generous and can be triggered for money if necessary. The details that are disappointing are the low RTP and volatility that is high, which leads to high risks. So it’s a normal slot, but not the one you should expect too much from.
