Greentube, the NOVOMATIC Digital Gaming and Entertainment division, is revving its engines and hitting the highway with Rumble Riches™ Haulin’ Gold™, its latest slot release where players join a seasoned trucker and his trusty sidekick on a feature-packed road trip.
Set along the open road, the game features five independent reels in a classic 5×3 layout with 50 fixed paylines. Coins play a central role, with players needing to land at least six to collect their accumulated value, all while building up the coin stack on the truck for bigger payouts.
At the heart of the action is the Rumble Riches™ feature, which can trigger at any time during base or bonus play. Players may be awarded the Add Coin feature, boosting the reels with additional coin symbols, or Add Wild, injecting extra wilds across reels to enhance win potential and create powerful combinations.
Landing three Bonus scatter symbols across the middle reels unlocks eight Free Games, giving players more chances to keep the wheels turning. During both the base game and free spins, landing six or more coins activates the Lock & Spin feature, where the road to riches opens up.
Lock & Spin introduces up to 30 reels, with spins resetting whenever new symbols land. Each newly landed coin resets the spins counter back to three, extending gameplay and increasing the chance to build bigger wins. Coin symbols can lock in place, while special modifiers keep the gameplay unpredictable.
Truck symbols bring added excitement, with the Red Truck collecting all visible coin values, the Purple Truck boosting coin values throughout the feature, and the Blue Truck enhancing all coin values in one go.
The convoy-style feature elevates the experience to new heights, with the Green Truck triggering a passing convoy that adds together a range of cash values and jackpots, while unlocking all rows opens the Golden Garage, launching the Gold Convoy bonus for even greater rewards.
In selected markets, players can also access the Lock ‘N’ Spin bonus instantly via the popular Bonus Buy feature for 75x the bet.
Rumble Riches™ Haulin’ Gold™ marks the latest instalment in Greentube’s growing portfolio of premium slot content, following recent releases such as Gorilla Cash™, and Firecracker Frenzy™ Money Toad™.
Richard Ganster, Director of Games Strategy and Games Portfolio Management at Greentube, said: “Rumble Riches™ Haulin’ Gold™ delivers a thrilling ride from start to finish, combining a unique, character-driven theme with a powerful mix of features and modifiers.
“This title builds on the classic Hold & Spin mechanic, evolving it with added depth through features such as the convoy bonuses, creating a more dynamic and engaging player experience. The trucking setting allows us to introduce mechanics that ensure players feel like they’re constantly moving forward on a rewarding journey. It’s a game built for momentum and big win potential.”
