Gameplay and Mechanics

Viking Lock is a 5×3-reel slot with 25 paylines. This means that you must land a combination of matching symbols on adjacent reels, starting from the leftmost reel, to win. The RTP (Return to Player) of this Boomerang Studios’ title is 95.79%. Accordingly, the typical payout is 95.79 coins for every 100 wagered.

The internet-based slot has a medium level of volatility, meaning that wins tend to be frequent but smaller than in games with higher or lower levels of volatility. The paylines here are fixed, so you cannot change them. In other words, all winning combinations must follow the payline rules.

To play Viking Lock, choose your bet amount and click the spin button. The reels will then spin and stop randomly. If you land a winning combination, you will win a prize.

Viking Lock Free Spins Bonus Round

You receive 5 initial free spins as a reward for activating the free spins feature, which requires landing three or more scatter symbols.

What makes this feature even more exciting is its progressive win multiplier. With each win you achieve during these spins, the multiplier increases by one, setting the stage for potentially larger wins as you progress.

But that’s not all—the Lock Reel feature is also activated with each spin throughout the free spins. If that’s not enough, the scatter symbols play a significant role during free spins.

Landing 2 scatters will grant you an additional free spin, while landing 3 or more scatters will boost your free spin count by 5. The best part is that the free spins are played with the same bet and lines as the triggering spin, maintaining the continuity of your gaming experience.

Lock Reel Feature

The Lock Reel Feature is an engaging mechanic that enhances your gameplay experience. Here’s how it works: Whenever the Lock Reel Feature is triggered, you’ll notice that two or more reels become linked together.

This linkage ensures that these reels display the same symbols when they halt, significantly increasing your chances of forming winning combinations. The magic of this feature unfolds on any base game spin, and what’s even more exciting is that the Lock Reel Feature can trigger at random, adding an element of surprise and anticipation to your spins.
