Book of Loki slot review
Book of Loki is a 1X2gaming slot from 2020 that takes the familiar book format into the world of the Norse trickster god. It plays on five reels and three rows with 10 paylines, and one symbol does two jobs: the Book of Loki is both the wild and the scatter. Three of them open 10 free spins with a special expanding symbol.

How Book of Loki plays
The base game is simple by design: wins pay left to right along the 10 fixed lines, with no ways, cascades or modifiers to track. The Book symbol can stand in for the regular symbols to complete a line, and it is also the key that opens the bonus, which means every Book that lands matters twice.
Anyone who has played a book slot will recognise the shape at once. The appeal is waiting for that third Book and then for the chosen symbol, rather than a stack of side features.
Free spins with an expanding symbol
Land three Books and 10 free spins are awarded. Before the first of them, one regular symbol is chosen at random to be the special expanding symbol for the whole round. When it lands on enough reels to form a win during the free spins, it can stretch to cover its full reel, which can turn a scattered handful of icons into wins along several lines at once.
The higher-paying symbols tend to make the most of this, since a full reel of a premium can reach across many lines. Landing three or more Books again inside the round can add more free spins, giving the expanding symbol further chances to appear.
