Book of Halloween slot review
Book of Halloween is Inspired Gaming’s spooky take on the classic “Book of” format, played on 5 reels and 3 rows with 10 paylines. A single book symbol does two jobs as wild and scatter, and three or more of them unlock 10 free spins in which one randomly chosen symbol can expand to fill whole reels.

How Book of Halloween plays
Anyone who has played a “Book of” slot will recognise the shape of this one: a compact 5x3 grid, 10 lines and a high-volatility pay structure where much of the potential sits in the free spins. Inspired dresses it in a gothic graveyard look, with four themed premium symbols above the A, K, Q, J and 10 card ranks.
- Pumpkin – the top regular symbol.
- Cauldron – the second-highest payer.
- Tombstone and skeleton hand – the lower two premium symbols.
- Book – wild and scatter in one, substituting for the other symbols and paying in any position.
The book also pays on its own as a scatter: three anywhere return 2x your total stake, four return 20x and five return 200x, on top of starting the feature.
Free spins with an expanding symbol
Three or more books trigger 10 free spins, whatever the number of books. Before the first spin, one regular paying symbol is picked at random to be the special expanding symbol for the whole round.
When that symbol lands in enough positions to form a win, it grows to cover every row of the reels it sits on, and the win is worked out again across the lines. A pumpkin or cauldron chosen as the special symbol usually counts for more than a card rank, but any symbol can be picked.
