RTP Book of the Golden Lion by Zillion Games is a 5x3 slot with 25 paylines and a stated hit rate of 1.98. The game includes mystery symbols, full payline pop-up features, and a bonus structure built around free spins and Hold & Win-style mechanics. Minimum and maximum bets are listed at €0.1 and €100, with no bonus buy option.
According to the game details, three wilds can trigger free spins, while three scatter symbols also activate the free spins mode. In this round, accumulated symbols are carried into the feature, which changes the way winnings can build during play. A full payline may also trigger a special pop-up event.
The Hold and Ring bonus game adds a collector element: when the bonus round ends, the player receives the total value of all bonus symbols collected. If all 15 bonus symbols land, the GRAND JACKPOT is awarded. The demo version is available to play for free, which allows users to practice before playing for real money.
