Highway to Bell Stack & Collect

Highway to Bell Stack & Collect is a hard-rock slot from Novomatic, built by its Greentube studio and released on 22 September 2026. The reels stand on a stage at a fiery concert in hell, with a giant golden bell hanging over the right-hand side and a crowd of silhouettes at the bottom. The game uses 5 reels and 4 rows with 20 fixed win lines, and its bonus is built around glowing Fireball coins that are collected by bells. The volatility is medium to high.

Welcome To The Hell-Rock Stage

The artwork is loud and colorful. A red-skinned singer with a microphone is the star of the artwork, while the symbol set is made of an amplifier Wild, a red devil, an orange horned demon, a purple punk guitarist, a guitar, crossed drumsticks and three guitar picks marked with card letters. Fireballs are round golden coins that carry a cash value, and they are the symbols to watch in every part of the game. The mix of metal imagery and cartoon characters gives the slot a playful look instead of a gloomy one.

Symbols And Wins

Wins form on the 20 fixed lines, from left to right on adjacent reels. The amplifier Wild and the red devil are the top payers: five of a kind pays 10x the bet, four pays 5x and three pays 2x. The orange demon pays 6x for five, 3x for four and 1.2x for three, and the purple guitarist pays 3x, 2x and 1x. The lower values go to the guitar (1.6x for five), the drumsticks (1.4x) and the three guitar picks, which pay between 0.6x and 1x for a full line. Because the payouts are modest, most of the excitement in this slot comes from the Fireball features rather than from line wins alone.

Bell Collect And Mystery Bell Collect

Two collect mechanics work in the base game. When Fireballs land together with the Bell Collector, the Bell Collect starts: the bell tolls and gathers the values of all Fireballs on the reels, adding them together with every toll, and the total is paid at the end. When Fireballs land without the Bell Collector, the Mystery Bell Collect may start at random. The values then fly toward the giant bell outside the reels, which collects them in the same way. Both features turn a spin with a few coin values into a payout that is larger than the sum of the parts.

The Stack & Collect Bonus

The main bonus begins when three Microphone symbols land on reels 1, 3 and 5. The round starts with 3 free spins, and the counter goes back to 3 every time a new Fireball or an Incrementer symbol lands. An Incrementer adds its value to every Fireball visible on the reels and then turns into a Fireball itself, so the coins on screen grow quickly. Once a whole reel is full of Fireballs, the bell above that reel collects their values and adds a multiplier that can rise up to 3x. In the bonus screen the multipliers show on top of each bell, and a Feature Win box on the right keeps a running total.

Each reel can be collected up to three times before it locks, and every locked reel moves the player closer to the Grand Prize. A fixed Grand jackpot of 1,000x the bet is shown on the left side of the bonus screen. The mix of resetting spins, growing coins and bell multipliers makes the bonus tense, because a spin without a new coin brings the round closer to its end, but one lucky Incrementer can change everything.

Extra Bet Options

The Extra Bet button on the left of the reels opens a panel with two optional bets that raise the stake. Inferno Bet costs twice the normal bet (2.00 on a 1.00 stake) and brings more Fireballs with a higher average value. Bonus Bet costs 1.2 times the bet (1.20 on a 1.00 stake) and increases the chance of triggering the bonus. Both are optional, so the standard bet remains a fair way to learn how the collects behave.

Reading The Fireballs

The coin values are the language of this slot, and they are shown directly in euro amounts that follow the bet. On a 1.00 stake the base game already shows Fireballs worth 0.20, 0.40, 1.00, 2.00, 3.00 and even 20.00, and inside the bonus the board can display amounts such as 5.00, 10.00 and 30.00 on a single screen. Since the Bell Collect adds every visible value together, the number of coins on the reels matters as much as the size of any single one. Three or four Fireballs next to the Bell Collector can be worth more than a full line of high symbols.

How A Bonus Round Builds Up

A typical bonus starts almost empty, with a single coin and three spins on the counter, which is why the first spins feel tense. Then the board fills: new coins refresh the counter, an Incrementer lifts every coin at once, and the first reel to fill triggers its bell. Once the multiplier banners appear above the reels, the Feature Win box starts to move quickly. On a 1.00 bet it can jump from 58.00 to 77.40 and on to 126.60 as more reels collect, and the locked reels glow in orange to show where the next collection will happen. Every collection also pushes the game closer to the Grand Prize, so the last spins can be the most rewarding.

Controls And Look

The bottom bar is classic Novomatic: Menu, the number of lines, the total bet, a Max Bet button, Auto and Turbo switches and a green Start button. The Menu opens the paytable and info pages, the settings, the help and the exit option. The demo starts with a short age check and a few rule screens that explain the Bell scatter, so first-time players get a quick tour before the first spin.

Is It Your Kind Of Slot?

If you like Fireball-and-coin slots with collect mechanics, this one offers a fresh twist with the bell collectors and the reel-locking bonus. The theme is bold and the animations of the bell are satisfying. Because the paytable is on the low side, patience is needed between bonuses, so smaller stakes are a sensible way to explore it. Try the free demo above and watch how the bells collect before you decide whether to play for real money.
