Greentube, the NOVOMATIC Digital Gaming and Entertainment division, is shifting into high gear 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 against an open-road backdrop, the game features a classic 5×3 layout with 50 fixed paylines. Coins play a central role: players need to land at least six to collect their accumulated value while building up the coin stack on the truck for even bigger payouts.
At the heart of the action is the Rumble Riches™ feature, which can trigger at any time during both base and bonus play. This includes:
- Add Coin – adds extra coin symbols to the reels
- Add Wild – injects additional wilds to boost win potential and create powerful combinations
Landing three Bonus scatter symbols across the middle reels unlocks eight Free Games, offering more chances to keep the wheels turning. Both during base play and free spins, collecting six or more coins activates the Lock & Spin feature, opening the road to even bigger rewards.
Lock & Spin expands up to 30 reels, with spins resetting whenever new symbols land. Each newly landed coin resets the spins counter to three, keeping gameplay extended and excitement high. Coins can lock in place, while special modifiers maintain unpredictability.
Truck symbols introduce further thrills:
- Red Truck – collects all visible coin values
- Purple Truck – boosts coin values across the reels
- Blue Truck – enhances all coin values in a single hit
The convoy-style feature takes gameplay to the next level: the Green Truck triggers a passing convoy that adds together multiple cash values and jackpots. Unlocking all rows opens the Golden Garage, launching the Gold Convoy bonus for even bigger rewards.
In select markets, players can access Lock ‘N’ Spin instantly via the Bonus Buy feature for 75x the bet.
Rumble Riches™ Haulin’ Gold™ is the latest addition to Greentube’s premium slot portfolio, following successful 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 evolves the classic Hold & Spin mechanic with convoy bonuses, creating a more dynamic and engaging experience. The trucking theme allows us to build momentum, keeping players moving forward on a rewarding journey with big win potential.”
