In 2025, the developer Greentube delighted us with its new slot machine, Lock Breakers Goblin Bros. This new game in their catalog uses mechanics such as locked coins and jackpots, magic spins, and rewind. If you’re familiar with these mechanics and have already appreciated their potential, don’t hesitate to try this new game. If you’re hearing about it for the first time, this review will tell you more about it and highlight its main advantages.
This slot machine features medium volatility and an RTP of 94.55%, with a maximum payout of over 2,000 bets. These parameters indicate that you have the potential to receive moderate wins fairly frequently. While the RTP isn’t particularly high, this only becomes apparent over the long term and doesn’t prevent you from winning big. We’ll go into more detail later in this review.
In Lock Breakers Goblin Bros, you’ll delve into the goblins’ underground world, where you’ll discover hoards of gold and coins, mines, and mysterious caves. The slot machine is packed with animations and visual effects, making the game more intense and dynamic. Goblins appear alongside the grid, reacting to your wins and creating a fun and lively atmosphere. It’s an entertaining game that will keep you entertained.
Despite the high-quality graphics and numerous visual effects, the slot machine runs stably, even on mobile devices. This is made possible by HTML5 technology, which allows you to play comfortably in a browser without downloading a specific application.
The sound design is perfectly consistent with the graphics. The typical music of gold prospectors, the sound of coins, and the miners’ taps create total immersion in the atmosphere of the slot machine.
In the Lock Breakers Goblin Bros slot machine, the symbols are placed on a 5×3 grid, and you have 40 fixed paylines. Winning combinations consist of 3 to 5 identical symbols on a payline. It is important that the symbols are positioned from left to right, starting with the leftmost reel. Each symbol awards a specific multiplier, the payout of which depends on the bet, ranging from $0.20 to $100 per spin.
Please note that the payouts for traditional combinations on the paylines are low. The highest paying symbol is a bag of gold coins, with multipliers ranging from x0.6 to x4. This is a small amount, which explains the low return to player (RTP), and winnings are heavily dependent on bonuses.
The lowest-paying symbols are traditionally represented by cards from 9 to A. Their minimum multiplier is x0.05 and their maximum is x0.1. Again, you’ll find that the payouts are small and you won’t be able to maintain a positive balance solely through winning combinations. That’s why it’s important to study the slot machine’s bonus features.
The bonuses in the Lock Breakers Goblin Bros game form the basis of your winnings. To play profitably, study all the features of the online slot machine.
A random feature of the base game, which can be activated at any time. A goblin appears in the center of the screen, then locked coins and random Jackpot symbols are added to the reels. This feature allows you to win big instantly.
The Goblin in the center can rewind one or more symbols to transform a normal symbol into a Locked Jackpot or a Coin. This feature is triggered randomly during the base game and free spins.
The central symbol on the game board is framed. Not only can standard symbols from the paytable land on the grid, but also coins of certain values. If coin symbols appear on the reels and the Goblin lands in the central cell, you will collect all the values and win the corresponding payout.
When two ore wagons filled with coins overflow, they explode. Exploding each wagon grants 6 free spins. Exploding two wagons grants 12 free spins. Further explosions are also possible during the bonus spin, increasing the number of free spins.
During free spins, the Goblin becomes a sticky Wild: it remains in the center position throughout the bonus round, adding coins to the wagons. You collect all the locked coins and the locked jackpot to win big.
In the base game and free spins, you can win jackpots. However, during free spins, the odds are much higher. You will win the jackpot if a goblin is in the center space and the corresponding jackpot symbol is present on the board.
By placing a 60 bet, you can instantly trigger the free spins. The goblin will quickly fill a cart and activate 6 free spins. You can also choose the opportune moment to activate the real money bonus round and thus activate 2 carts simultaneously.
The slot machine’s medium volatility ensures a high frequency of wins. Regular wins, even modest ones, allow you to stay in the game longer and wait for the activation of larger bonuses. The return to player (RTP) is 94.55%, which is low. This is due to the low payout rate of standard combinations on the paylines.
The Lock Breakers Goblin Bros slot stands out with its medium volatility and unique locking coin and jackpot symbol mechanics, as well as its magic spins and rewind feature. These features create a dynamic gameplay experience and allow for big wins, even in the base game. This game is ideal for those who appreciate a well-balanced slot machine with an expressive design, high-quality graphics, and exciting bonus features.
