Mining Rush by Pragmatic Play

Grab your pickaxe and head deep underground with Mining Rush by Pragmatic Play. This gold-mining slot combines a large 7x7 grid with Cluster Pays, tumbling wins and an unusual Nugget feature. The result is a game where ordinary winning clusters can keep developing as symbols disappear and new ones fall into place.

The game uses a 7x7 grid with Cluster Pays instead of traditional paylines. A winning cluster requires at least 5 matching symbols connected horizontally or vertically. This means winning combinations can form in many different shapes across the grid.

The main symbols include the cheerful Miner, a gold-filled Mine Cart and a Pickaxe. These higher-value symbols are joined by traditional card symbols from J through A. The Miner is the highest-paying regular symbol, while the lower-value symbols provide more frequent opportunities to create clusters.

Mining Rush does not use a conventional Wild symbol. Instead, the game's main excitement comes from its Tumble mechanic and Nugget feature.

Whenever a winning cluster lands, those symbols are removed from the grid. New symbols then tumble down from above to fill the empty positions. If another cluster forms, it pays again and another tumble takes place. This process continues as long as new winning clusters are created.

The game's special Dynamite Scatter symbols provide another important feature. When a winning combination includes a Dynamite Scatter during the base game, the Scatter transforms into a Mine and remains locked on the grid for the rest of the round.

Each Mine keeps track of the wins it helps generate. Every successful tumble involving a Mine adds one point to its progress. Once a Mine collects three points, it upgrades to the next level and awards a higher-value prize.

There are four Nugget levels available. Bronze Nuggets can award up to 5x the bet, while Silver Nuggets can reach 20x. Gold Nuggets can award up to 100x, while the highest Diamond Nuggets can be worth an impressive 1,000x the bet.

This upgrading mechanic gives the base game a clear sense of progression. A Mine does not simply remain at one value throughout the round. Instead, repeated winning tumbles can gradually increase its level and potential prize.

The Free Spins feature provides the game's biggest opportunity to build valuable Nuggets. Landing 3 or more Dynamite Scatters triggers the bonus round. The number of Scatters determines how many Free Spins are awarded, with the feature providing between 8 and 20 spins.

The triggering Scatters transform into Nuggets when the Free Spins begin. These Nuggets become sticky for the entire bonus round, meaning they remain in their positions instead of disappearing after a tumble.

Each sticky Nugget has its own starting level and cash value. As winning tumbles occur, the Nuggets can collect additional points. Once a Nugget reaches three points, it upgrades to the next level and can potentially produce a much larger prize.

There is another useful Free Spins mechanic. Every new Mine created during the bonus awards 2 additional Free Spins. This means the feature can extend considerably when the reels continue producing new Dynamite Scatters.

The Free Spins round also carries over the progress of Mines from the base game. Any Mines already present when the bonus begins keep their existing level and accumulated points. This gives players an additional reason to watch those Mines develop during the regular game.

Mining Rush is officially listed with high volatility and a maximum win of 10,000x the bet. The game is available with several RTP configurations, including a maximum published RTP of 96.56%. The exact RTP can vary between casino versions, so it is worth checking the game information before playing.

A Bonus Buy option is also available in supported markets. This allows players to purchase access to the Free Spins feature instead of waiting for the required Scatter combination to land naturally. Availability and pricing depend on the particular casino and local regulations.

Overall, Mining Rush by Pragmatic Play offers a clever combination of Cluster Pays, Tumbles and upgrading Nuggets. The Mines give ordinary spins a sense of progression, while the Free Spins turn those mechanics into a much more persistent collecting feature.

The 1,000x Diamond Nugget provides one of the game's most attractive individual prizes. Meanwhile, the 10,000x maximum win gives the overall game plenty of potential when multiple features combine successfully.

If you enjoy mining themes, Cluster Pays, Tumbles, Free Spins and collecting features, Mining Rush is well worth trying in free play. Grab your pickaxe, keep those Mines growing and see whether you can uncover a valuable Diamond Nugget.
