Firework Fusion Features & Mechanics
Feature & Jackpot Token Symbols
Feature symbols and Jackpot Token symbols act as overlay symbols that sit above regular reel symbols. Once activated, they disappear to reveal the symbol underneath and do not provide direct pay outs themselves. Feature symbols are used to upgrade and trigger the various feature tabs positioned above the reels, while Jackpot Tokens contribute toward the Collection Pot feature.
HOT MODE Feature
HOT MODE can randomly activate during the base game. While active, additional Feature symbols are added to the reels, increasing the chances of triggering feature tab prizes. The mode remains active for a random number of spins or until the Walking Wilds feature is triggered.
During HOT MODE, the Collection Pot and Free Spins features are temporarily disabled, and the mode itself cannot activate while Walking Wilds are already active.
Feature Tabs
Each reel has its own feature tab positioned above it. Landing Feature symbols upgrades or activates the prize attached to the corresponding reel.
Multiple feature tab prizes can trigger during the same spin and are resolved from left to right.
Wild Multipliers
Located above reel 1, this feature awards Wild multipliers ranging from 2x up to 10x. The multiplier applies only to wins containing the affected Wild symbol.
Mini Jackpot
Located above reel 2, this feature awards between 10x and 30x the total bet. Feature symbols increase the jackpot value progressively.
Extra Wilds
Located above reel 3, this feature adds between 2 and 10 additional Wild symbols to random reel positions.
Minor Jackpot
Located above reel 4, this feature awards between 30x and 80x the total bet, with upgrades increasing the jackpot value further.
Walking Wilds
Located above reel 5, this feature awards between 1 and 3 Walking Wilds. These Wilds begin on reel 5 and move one reel to the left on each subsequent spin before eventually disappearing after passing reel 1.
Feature Upgrade Trail
Landing 1 or 2 Scatter symbols during the base game contributes progress toward the persistent Feature Upgrade Trail.
As more Scatters are collected, the next Free Spins feature receives increasingly larger multipliers:
- 1.5x multiplier at 60 collected Scatters
- 2x at 145
- 2.5x at 270
- 3x at 405
- 5x at 555
The Feature Upgrade Trail does not reset after triggering Free Spins and remains persistent throughout gameplay.
Collection Pot Feature
Jackpot Token symbols collected during the base game may randomly trigger the Collection Pot feature.
When activated, players spin a Jackpot Wheel capable of awarding one of four prizes:
- MINI Jackpot
- MINOR Jackpot
- MAJOR Jackpot
- GRAND Jackpot
The GRAND prize awards the game’s top jackpot value of 5,000x the total bet.
After the Collection Pot feature concludes, the pot resets upon returning to the base game.
Free Spins Feature
Landing 3 Scatter symbols anywhere on the reels awards 10 Free Spins.
Before the feature begins, a Free Spins Wheel determines one of three bonus variants:
Extra Wilds Free Spins
Every reel receives an Extra Wilds feature tab capable of adding multiple Wild symbols each spin.
Wild Multipliers Free Spins
Each reel gains Wild Multiplier tabs capable of awarding additive Wild multipliers between 2x and 10x.
Walking Wilds Free Spins
Every reel gains Walking Wild feature tabs capable of spawning moving Wilds across the reels.
The Feature Upgrade Trail multiplier applies to all wins throughout Free Spins, and upgrades earned during the feature remain active for the full duration.
Free Spins cannot be retriggered.
Additional Features
Upsizer Feature
After the Free Spins Wheel result is revealed, players may optionally purchase a stronger version of the awarded Free Spins feature before the round begins.
Bonus Recharge
At the end of Free Spins, players may be offered the chance to continue the bonus feature for an additional cost based on the current game state.
Conclusion
Firework Fusion combines colourful festival-inspired visuals with a heavily feature-driven gameplay structure focused on upgrades, Wild mechanics, and progressive bonus systems. The combination of feature tabs, HOT MODE activations, and persistent upgrade trails creates strong momentum throughout both the base game and Free Spins.
The game’s biggest strength lies in the variety of its mechanics. Walking Wilds, expanding Wild features, jackpots, and multiplier-based bonuses all work together to keep the gameplay highly active, while the Feature Upgrade Trail adds a long-term progression element that continuously improves future bonus rounds.
The different Free Spins variations also provide strong variety, allowing the gameplay experience to shift between multiplier-heavy setups, additional Wild generation, or moving Wild mechanics depending on the feature awarded.
