Book of Admiral Slot Review

Book of Admiral Slot - Game Review

Book of Admiral is a 5x3 slot from Amatic with 10 fixed paylines and a classic high volatility model. The theme sends you to sea with an admiral on the deck of a warship, but the visuals feel like a blast from the past rather than a flashy modern release. I like the clear layout and simple controls, although some players used to slick graphics might find the production values below average.

You can spin Book of Admiral from £0.10 up to £100 per round, so the betting range covers cautious players and high rollers. The headline number is a 5,000x max win, which lines up with the top symbol paying 500x on all ten lines. One source quotes an RTP of 97.05%, while another notes no official figure, so I treat it as a high-return but swingy “Book of” style slot.

Book of Admiral Slot Features

Under the bonnet, Book of Admiral sticks very closely to the familiar “Book of” template. You get nine regular pay symbols and a single special Book symbol carrying the whole feature package. Wins land when three or more matching icons line up on one of the ten paylines from left to right. In the base game, it is mostly about grinding spins, waiting for the books to drop and set off the feature.

The Book symbol pulls double duty as both wild and scatter. As a wild, it appears only in the base game and substitutes for all other symbols to help complete line wins. This keeps things moving between bonuses and softens some of the dead spins you expect from a high volatility slot. As a scatter, it pays by itself and is the key to triggering free spins whenever three, four, or five land anywhere in view.

Once you are in the bonus, the traditional expanding symbol mechanic carries the gameplay. Before the first free spin, one regular symbol is chosen at random to become special. When this special symbol can form a win, it expands to cover entire reels and pays as if on all positions, even if the symbols are not next to each other. Retriggers gradually add more expanding symbols, so the feature can snowball in a satisfying way.

Book of Admiral Symbols and Paytable

Book of Admiral uses the standard split between low card ranks and thematic picture symbols. Tens through Aces make up the lower tier, paying up to 10x your stake for five of a kind on a line, with smaller hits for three or four. The more exciting payouts sit with the themed icons, which fit the naval setting better and carry the potential needed to reach that 5,000x cap on a single spin.

The admiral is the star symbol, paying 500x for five on a line, 100x for four, 10x for three, and even 1x for just two, so full screens of him across all ten lines can reach the advertised jackpot level. Ships, cannons, and compass-style emblems follow with top prizes of 200x or 75x for five. The Book scatter itself pays up to 200x for five, alongside its wild and bonus-trigger roles.

Book of Admiral Slot – Free Spins Feature

Hit three, four, or five Books anywhere on the reels and Book of Admiral awards 10 free spins with an expanding symbol feature. One regular symbol is chosen at random to become special during the round. Whenever a win is possible, that symbol expands vertically to fill its reels and pays even when the winning reels are not adjacent. Retriggers add more free spins and another expanding symbol each time, up to a maximum of nine specials.

Book of Admiral Review Summary

From a seasoned player’s point of view, Book of Admiral is an average “Book of” slot with a nautical skin. The gameplay loop is familiar, the feature set is straightforward, and the graphics look a bit dated. On the positive side, the combination of a quoted 97.05% RTP, high volatility, and a 5,000x top prize makes it capable of serious hits if the expanding symbols line up during a well-timed bonus.

I reach for Book of Admiral when I want that classic expanding symbol tension without learning a new set of mechanics. If you enjoy simple, volatile slots and do not mind old-school visuals, the game does its job well enough. If you expect fresh twists, layered features, or modern animation, it will probably feel too formulaic, and you might sail on past it after a short session.
