Highway to Bell Stack & Collect™

Highway to Bell Stack & Collect™ is a video slot developed by Novomatic's Greentube division, featuring a layout of 5 reels and 3 rows with 20 fixed paylines. The "Hell-Rock" theme creates a rock concert atmosphere in Hell, with symbols of fireballs, huge bells, microphones, amplifiers, and extraordinary characters. In the base game, players can activate two collection mechanics: Bell Collect, which is triggered when fireballs land next to the Bell Collector, and Mystery Bell Collect, which activates randomly when fireballs land without the Bell Collector.

The Stack & Collect™ bonus round is triggered by three microphone scatter symbols on reels 1, 3, and 5, starting three free spins. Each time a new fireball or booster symbol appears, the free spins reset to three. Boosters increase the value of visible fireballs, which then turn into real fireballs, contributing to collections on the reels.

When a reel is completely filled with fireballs, the bell above collects the values and applies a multiplier of up to 3×. During the bonus round, each reel can be collected up to three times before locking, pushing the player towards the Grand Prize. In some versions of the game, the Buy Bonus option is available, allowing direct access to the Stack & Collect Bonus. Additionally, there are optional betting features, such as Bonus Bet and Inferno Bet, which increase the frequency of bonus triggers and enhance fireball rewards.

You can play it for real money.
