Lock and Key: Slot Review and Free Play Demo

Lock and Key Review

Lock and Key is one of the newest online slot releases of Slot Factory, a highly reputable provider part of Skywind Group. It offers high-quality and mobile-friendly gameplay on any device! The title is designed in a rather simplistic way but has its benefits, and we highly suggest it!

The board has 5 reels and 3 rows, and players can score big on 15 fixed winning lines. It's controlled via a transparent Spin button to the left and several technical features. As usual, the provider has added an infinite Autoplay, but no Quickspin enhancements are available. Still, the dynamics are just fine!

Lock and Key offers several special features, intertwining and increasing the potential of the game. There is a wild symbol in play that substitutes for all the others except the scatters. All wins are oriented from left to right, starting from the leftmost reel, and combinations must consist of 3, 4, or 5 matching symbols.

Lock and Key Slot: RTP, Free Spins and Respins

The Lock and Key RTP is ranging, and so far, we have found three different online versions. The highest rate is 96.02%, while the lowest is 91.98%. In all cases, the volatility levels are expected to vary from low to medium, but low-RTP variants remain too dangerous.

Slot Factory loves to challenge strategy experts and packs its video slots with very wide betting ranges. The situation is not much different here, and you can set your wager from £0.15 to £300 per spin! There is no technical cap on winnings, and the total payout will be limited by the chosen casino only!

Wild symbols pay the most if they are lined up - 50x, 100x, or 150x the bet per line. The slot Logo follows with rewards from x45 to x125. The medium-valued symbols are Dollar Signs, Triple Gold Bullion, Double Gold Bullion, and Gold Bullion, paying up to x110, x100, x95, and x90, respectively. Royalties are the minor symbols, while 10s and 9s are the lowest-valued figures.

The Sticky Respins feature may activate randomly after any non-winning spin during the base game. If there are wild symbols in view, they will lock on their positions, and the others will spin, searching for a reward. The special Key symbol may land on the locked wilds, and if so, it will add an x2 multiplier!

The Lock and Key online slot is loaded with a Free Spins feature as well. Three, four, or five scatter symbols anywhere on the grid activate 5, 10, or 15 free rounds, respectively. No more can be added during the feature, but the lowest-paying symbols, 10s and 9s, are removed from the reels.

Furthermore, during the bonus minigame, each non-winning round will always activate a partial grid respin with all other features in play. Therefore, each of the awarded free spins will deliver a prize. It's a pity that such an exciting feature can't be bought or won in an alternative way!

Our Conclusion

Just in Slot Factory's style, Lock and Key is a straightforward video slot with huge potential for providing payouts and fun! We carried over numerous test spins and can confirm that the base-game features are quite common. You can try them with no risk via the free demo at the beginning of this slot review.

Sadly, we can't say the same about the Free Spins game, which could be really generous and perhaps that's why it's also rare. The wide range of stakes is a great opportunity to polish your slot skills. Implement a betting strategy to optimize your performance and results!
