Golden Grimoire

Golden Grimoire by NetEnt is a five-reel, four-row video slot with 20 fixed paylines and an alchemy-themed design. The main game includes mystery symbols on reels 3, 4 and 5, where landing one or more can transform them into a randomly selected symbol, including a wild. Wilds substitute for all symbols except scatter and mystery symbols.

Three scatter symbols on reels 1, 3 and 5 trigger eight free spins. In the bonus round, the mystery feature changes to a sticky mystery symbol on reels 2, 3, 4 and 5, which can support repeated wins during the feature. The game also shows win presentations such as Mega Win, with the chance of larger totals when several free spins connect.

This demo version lets players play for free and practice before playing for real money. The slot uses a dark magical book setting with spellbooks, crystals and glowing symbols, while the paytable and feature screens focus on free spins, symbol transformations and cumulative win tracking.
