Book of Oz Lock 'n Spins Slot Game Background

Triple Edge Studios is a relatively new online slot game development studio in the iGaming industry; however, it is a studio which has already established itself within the online casino industry. Founded in 2018, they have released popular titles like Book of Oz Lock 'n Spins, Sisters of Oz Jackpots and the Fire and Roses Joker slot games. Since its inception, Triple Edge Studios has formed partnerships with other great casino operators and studios to improve the slots they produce.

Book of Oz Lock 'n Spins Game Design

Book of Oz Lock 'n Spins takes place in the legendary green crystal city from the story, but more specifically, in a luxurious-looking palace. The background depicts emerald pillars on either side of the play table and a large green glass window behind the playtable. The accents of the windows, walls, and pillar columns are made from gold and add to the lavish atmosphere created by the jewel building. The play table is less vibrant, featuring a black canvas with a golden border on the outside and separating each reel.

Locked Reels Feature

The Locked Reels feature allows players to lock up to 4 reels in place and spin only the non-selected reels. This feature will, however, affect the player's stake in Book of Oz Lock 'n Spins, depending on how many reels are selected and the types of symbols present on the reels.

On top of this, there is a Wild Scatter symbol which can substitute for other symbols on the play table to form matching symbol combinations in Book of Oz Lock 'n Spins.

Book of Oz Lock 'n Spins Free Spins

Landing 3, 4, or 5 Scatter symbols on the play table awards 10, 12, or 25 free spins. A special symbol gets randomly chosen at the start of the round.
