Book of Merlin by 1x2Gaming is a 5-reel, 3-row slot with six fixed winlines and high volatility. The game uses a fantasy library setting, with symbols including card values, a wand, a potion, and the book itself. The RTP is listed at 95.8%, with bet sizes from 0.1 to 50.
The book symbol has a dual role. It acts as a wild in regular play, substituting for non-special symbols, and also works as a scatter to trigger features. Landing three or more book symbols can award free spins, with the paytable and bonus screen showing a 10 free spins round. The demo version lets players review these rules and practice before playing for real money.
Payout information shown in the game notes includes smaller returns for card symbols and higher values for premium symbols such as the book and wand. The visual design uses an illustrated Merlin theme with ornate frames, spellbook screens, and a parchment-style interface for the winlines and bonus details.
