Book of Grimm is a 5×3 slot with 10 fixed paylines from Hölle Games. You can play with stakes between €0,10 and €50 play. The game combines classic "Book" mechanics with a dark, fairytale atmosphere. The playing field consists of five reels with three symbols each. All winnings only count from left to right, starting with the first reel. Only the highest win is paid out per winning line, while winnings on multiple lines are added together.
The most important symbol is the "Book of Grimm". It has a dual function: on the one hand, it is the wild symbol and can stand in for all other symbols to complete winning combinations. On the other hand, it acts as a scatter. If you hit at least three of these books anywhere on the reels, you will not only receive an instant payout, but also free spins.

free Spins with Expanding Symbol
The free spins round is triggered when at least three scatter symbols appear on the reels and bring you 10 free spins. Before it starts, a special symbol is randomly chosen. This symbol can expand to cover the entire reel during the free spins if enough of them appear to form a winning combination. What's special about it is that the expanded symbol pays out regardless of fixed paylines, as long as enough of them appear on the reels.
If you hit three or more books again during the free spins, there are 10 more free spins – and there is no limit.
risk feature
After each win, you have the opportunity to place your winnings in the risk game. You can either choose the card risk option, where you bet on the correct card color or symbol, or the ladder risk, where you aim for gradually higher winnings. If you don't want to rely on luck, you can also collect your winnings straight away.
📝 NovNetco review about Book of Grimm:
Book of Grimm stays true to the popular "Book" game principle, but brings a special atmosphere to the game with its dark fairytale style. The free spins round with the expanding symbol in particular can provide high winnings. If you like classic slots with a mystical touch, then this game is definitely worth a look.
