Curious about the gameplay, the exciting bonus features, and the unique symbols that make this slot stand out? Keep reading to explore everything Lock and Pop has to offer!

Gameplay and Mechanics

Lock and Pop is played on a 5×5 grid, though only three rows are active during the base game, expanding during the bonus rounds. With 20 paylines, players can anticipate a blend of regular and special winning combinations. The slot’s RTP stands at a default of 96.09%, but variations exist for different markets. Classified as having low to medium volatility, it appeals to players who prefer steady, less risky gameplay.

Bets range widely from a minimum of 0.20 to a hefty maximum of 120 per spin, catering to both casual players and high rollers. The max win potential is a significant 4,046 times the bet, offering enticing rewards for those lucky spins.

Lock and Pop features a convenient autoplay option, allowing players to set a number of automatic spins. Unique to this slot is the “Prize” symbol mechanic, where hitting six or more Prize symbols triggers the free spins round. Here, these symbols become sticky, remaining on the reels until the round ends or a special feature is activated. Additionally, players can bypass the base game entirely by using the bonus buy function, jumping straight into the bonus round action.
