Greentube has launched Highway to Bell Stack & Collect, a new Hell-Rock slot built around fireball collections, escalating bell multipliers and a feature-led bonus round. The 5-reel, 20-win-line game combines Bell Collect mechanics in the base game with a Stack & Collect Free Spins feature that gives players a route towards the Grand Prize.

Press release.- Greentube, the NOVOMATIC Digital Gaming and Entertainment division, has launched Highway to Bell Stack & Collect, a Hell-Rock slot with 5 reels and 20 win lines, where blazing fireball symbols and a colossal bell combine to deliver powerful collect mechanics and a high-voltage feature set.

Featuring action-packed gameplay and big collect moments, the game gets the party started when fireball symbols land alongside the Bell Collector, activating the Bell Collect feature. The bell tolls, gathering the values of all fireballs, with each toll adding to the total before the accumulated value is awarded to the player once the collection is complete.

When fireball symbols land without the Bell Collector, the Mystery Bell Collect can randomly activate. The fireball values fly towards the giant bell outside the reels, which tolls and collects their values in the same way, awarding the total value to the player when triggered.

Landing three microphone symbols on reels 1, 3 and 5 triggers the Stack & Collect Bonus. Players start with three free spins, which reset whenever new fireball or incrementer symbols land. Each incrementer symbol adds its value to all visible fireballs on the reels before transforming into a fireball itself.

Filling a reel with fireballs causes the bell above it to collect their values, increasing its multiplier to 3x. Each reel can be collected up to three times before it locks, progressing players towards the Grand Prize.

Optional Bonus Bet and Inferno Bet features are also available, boosting the chances of triggering the bonus and increasing fireball rewards.

Highway to Bell Stack & Collect adds a hard-rocking, feature-rich title to Greentube‘s portfolio, combining a high-energy theme with layered collect mechanics designed to keep players engaged from the base game through to the bonus round.

The company said: “Highway to Bell Stack & Collect takes players to a rock concert in Hell, and every element of the game is built around that energy. The Bell Collect and Mystery Bell Collect keep the base game rewarding on every spin, so players always have something to watch for.

“The Stack & Collect Bonus is where the title really delivers. Locking in fireball values, reel by reel, and pushing towards the Grand Prize give players a clear sense of progression and a strong ceiling on win potential. It’s a title that fits operators looking for a hard-rocking hit with genuine depth to its feature set.”
