Quite an epic slot from Play’n Go guys.
Intro, graphics, plot are on the other level. The gameplay is not shabby either. Main feature is symbols’ splitting, basically a megaways mechanics. It’s especially exciting during FS, when chosen symbol splits after every spin.
It’s easy to lose the balance out of sight when u play this slot. Way too epic and flashy. My advice –check your balance every 30-40 spins, as down streaks are harsh here. That's ur price for epicness and big-win potential.

There are people who might think, that we already have too many Book concept slots, however, Play'n Go went a little further and did perfect job in reviving the concept with new and better looks and some interesting features along the way. Merlin's Grimoire is based on ways. It has 5 reels, however, the amount of ways can increase, meaning, that a symbol in free spins can also have more ways, that results in higher payouts. I am in love with this slot, since concept is nostalgic, but improved
