4 Fire Rockets by Kendoo sets a five-reel, three-row slot against Chinese festival fireworks. Its 25 paylines handle ordinary wins, while Bonus symbols lead into a Hold and Win round. Once there, the focus shifts to locked values, fresh arrivals and effects that can change both the prizes and the number of fields in play.
Quick take: A locked-symbol bonus gains extra interest when Double splits the action into independently spinning fields.
Theme and Gameplay
The fireworks setting fits a game built around several possible bonus effects. Between features, the compact reel layout gives the line game a familiar shape. Wilds substitute for paying symbols, but exclude Bonus symbols, keeping their line-building role separate from the feature chase.
That distinction is useful when reading a stop. A Wild can help an ordinary combination without replacing the Bonus symbol needed for feature entry. Once the bonus starts, the important question becomes whether another symbol arrives before the respins run out.
Slot Features
Hold and Win begins with three respins. Bonus symbols lock in place, and new arrivals reset the counter. The board therefore develops through accumulated symbols, with each fresh arrival buying more time as well as adding to the result.
Collect gathers values from a particular Bonus-symbol type and remains locked. Its reach is specific, so the kinds of symbols on the board matter alongside their amounts. Random multipliers can affect Bonus and Collect symbols, changing the value of those positions.
Double duplicates the board into independently spinning fields. This gives the feature two separate fields to follow, each capable of developing differently. Life can add a Bonus symbol near the end and refresh the respins, creating a possible extension when the round is close to finishing.
Feature focus: When Double appears, follow each field separately; their independent spins mean the duplicated boards can develop differently.
RTP and Win Potential
The multiplier values are 2x, 3x and 5x. The Grand jackpot pays 1,000x the bet, and Double allows two Grand awards without guaranteeing either. Those are specific feature prizes and effects, so the Grand amount should not be treated as a total-game ceiling.
My Thoughts On This Slot
Double gives this bonus its most appealing change of pace. Following two independent fields asks for more attention than watching one board fill, but it also makes the duplicated layout meaningful beyond its initial appearance.
Collect adds a useful distinction between symbol types, while Life can make a nearly finished round interesting again. Together, those effects suit someone who enjoys a Hold and Win feature with several moving parts. Anyone who wants one board and one straightforward collection rule may prefer a quieter version of the format.
Final Take: The split-board effect gives this fireworks bonus a clear reason to hold your attention.
