Book of Oz: Lock 'N Spin by Triple Edge Studios is a five-reel, 10-payline slot with high volatility and an RTP range of 96.35% to 96.6%. The game uses a fantasy-themed layout with symbols including a magician figure, letters, gems, a potion bottle, and a Book scatter symbol. Bet sizes range from 0.1 to 25.
The base game includes the Lock 'N Spin feature, where up to four reels can be locked for the next spin, increasing the total stake for that round. Wins are then awarded on the unlocked reels, which changes the way standard spins are played. A demo version is available, allowing players to play for free and practice before playing for real money.
Free Spins are triggered by landing 3, 4, or 5 Book scatter symbols, awarding 10, 12, or 25 spins. During the bonus round, a special expanding symbol is selected and can cover an entire reel when it appears, creating more winning combinations. The feature set also includes a 2nd Chance mechanic shown in the game information.
