The developer of the slot machine was the Estonian studio All41Studios, which closely cooperates with the leader in the world of virtual gambling, the Microgaming company. Lock A Luck is already their third joint project, before that they released such slots as Magic of Sahara and Le Kaffee Bar, for sure they are familiar to many fans of online games.

The bet per line ranges from 0.20 coins to 60 coins while the maximum win per spin is x1333.

To receive winnings, you should form prize chains. They should be formed on adjacent cells from left to right. When a line is filled with prizes, it will disappear, and all its winnings will be available for other combinations. Several winning combinations may be formed during the round, but the winnings will be credited for the most valuable ones. Prize chains are paid according to the paytable. Also, the amount of the final win will directly depend on the bet that the user set at the beginning of the round. The doubling game is not provided in the device, and there is also no progressive jackpot from All41Studios and the Microgaming company.

Bonuses do not matter for the purpose of prize calculations. Symbols are simple and easy to understand. The highest paid symbol is a diamond, it pays fifty times more than the bet placed for a set of five such elements. Less paid symbols are the jack, tens and nines icons.

Of the special symbols in the Lock A Luck slot machine, only the Wild symbol is represented, the Scatter is not provided in the game. Such an element is depicted in the form of a corresponding inscription. The wild symbol is able to replace all other elements, which contributes to an even greater formation of paid sequences. By itself, this symbol is not paid in any way. Wilds do not appear on all reels, but only on the second, third and fourth. The absence of a scatter symbol and multipliers is compensated by the function of locking the reels and the ability to get additional spins.

Bonus features of the Lock A Luck slot machine

The game does not provide free spins or other bonuses that players receive at other casino games. However, it still has one interesting bonus option that synchronizes the reels, which is called Locked Reels. During the gameplay, users will see that during each spin at least two virtual reels are synchronized and after they stop spinning, each of them will have the same set of symbols.

But this is not the only beauty of this choice. Further, two synchronized speakers are able to expand, which can subsequently capture three more reels. That means you'll get five synchronized columns on which there will be identical elements. From that it should be concluded that the number of chains formed will increase significantly and you'll get good winnings as a result.

The Lock A Luck slot is a 96.37% refund online casino gambling game with 27.74% frequency of formation of paid combinations. A 243 ways to make chains and the function of blocking the reels provide players with a good chance to receive large payouts.
