The Book of Amaterasu Slot Review

The Book of Amaterasu Overview

The Book of Amaterasu is a 5 reel, 3 row video slot from Mascot Gaming with 10 fixed paylines. The theme centres on the Japanese sun goddess Amaterasu and blends calm visuals with high risk maths. RTP sits around 95%, and the slot is highly volatile, so payouts can be quite spiky. I see it as a game for players who enjoy tense sessions and chasing those rarer, heavier hits.

I like how The Book of Amaterasu keeps the core mechanics simple yet hangs everything on one powerful mystery book symbol. You get a classic 'Book' structure, free spins with an expanding symbol, and the Risk 'N' Buy option that lets you jump straight into the bonus. It feels streamlined compared with feature packed slots, which suits longer, more relaxed play if you are comfortable with the volatility.

Theme and Graphics in The Book of Amaterasu

When I load up The Book of Amaterasu the first thing that hits me is how soothing it looks. Transparent reels sit over a dusk sky, rolling hills, temples and cherry blossom branches that gently sway. The palette leans on blues, purples and pinks rather than harsh neon, so the whole scene feels more like a meditation app than a hectic slot lobby banner.

On the reels in The Book of Amaterasu you get a mix of Japanese themed icons and classic card ranks. Amaterasu herself is the star symbol, joined by a lucky cat, ornate coin, theatrical mask and lotus flower. A, K, Q and J cover the lower wins. Everything has clean lines and a slightly painted style, which fits the tranquil mountain backdrop really well.

The Book of Amaterasu uses gentle audio cues rather than aggressive fanfares. Spins come with soft water sounds and muted drum knocks as the reels stop, while the main track sits in the background like calming flute music. Wins and feature triggers are picked out with subtle animations, such as Amaterasu blinking or the book glowing, which helps the slot stay relaxing even during long sessions.

The Book of Amaterasu RTP and Variance

The Book of Amaterasu is a high volatility slot with an RTP quoted at around 95%. On paper that sits just under what I would call average these days, so you need to accept a fair bit of risk. The hit rate of roughly 28.9% means wins appear often enough, but the bigger swings come from those rarer premium symbol hits and the stronger free spins rounds.

Stake levels in The Book of Amaterasu start at 0.20 for all ten lines and go up to around 20 per spin, depending on the version you play. You adjust the total bet via the control under the reels, with clear steps that suit low and mid stakes play. Because the max win figure is not shouted about, I treat this more as a steady grinder with occasional spikes.

Paytable & Wagering Sizes in The Book of Amaterasu

The paytable in The Book of Amaterasu follows a classic 'Book' pattern with a handful of high paying icons and simpler lows. Five Amaterasu symbols pay up to x500 your line stake, with the red and white cat at up to x200 and the gold coin or mask at up to x75. Lotus and A sit in the middle, while K, Q and J bring up the rear with wins up to x15 or x10.

The Book of Amaterasu Bonus Features

The core feature in The Book of Amaterasu is the mystery book symbol, which acts as both wild and scatter. As a wild it substitutes for all regular icons, filling gaps in line wins. As a scatter it pays anywhere and triggers free spins when you land three or more. Three books grant 10 spins, four books 15, and a full set of five books awards 25 free spins in one go.

Free spins in The Book of Amaterasu come with a special expanding symbol chosen at random before the round starts. When that symbol appears during the feature it can expand to cover its reel and pays on all lines, even if the icons are not adjacent. During testing I found that a good expanding premium can swing the balance of a session, especially when you retrigger and stack extra rounds on top.

The Risk 'N' Buy option in The Book of Amaterasu is handy if you do not want to wait for three books. After any spin you may get the chance either to buy straight into free spins for a set price, or risk a recent win to get cheaper access. I tend to use it sparingly, as the cost scales with stake size and the selected expanding symbol.

Overall The Book of Amaterasu Review

Overall, The Book of Amaterasu has become my go to slot when I fancy high volatility action wrapped in a calm package. The visuals and soundtrack keep me relaxed even when the balance is swinging, while the book mechanic and Risk 'N' Buy feature give enough control and excitement. The RTP is not thrilling and the line count is modest, yet the expanding symbol free spins keep me coming back.
