Slot Summary

A base-game win worth at least four times the stake opens Stellar Joker's central mechanic, a Super Game funded from the captured win. Greentube then shifts the slot from ordinary two-way line pays to Super Spins where Joker Wilds may expand across an entire reel. That threshold-based change, not the familiar fruit symbols, is what gives this high-volatility release its identity.
MechanicsSuper Spins introduce full-reel expanding Joker Wilds

How It Plays

The base game evaluates adjacent matching symbols across 10 fixed paylines. Combinations may begin on either outer reel, so results are read from both directions.

After a qualifying win, the player may collect the stored amount or spend it on Super Spins. Play ends after collection, meter depletion, or 50 Super Spins.

Theme & Atmosphere

Classic Fruit and Retro imagery anchor the ordinary reels, while the Joker and Star themes shift the special mode toward a more theatrical identity.

That contrast keeps the base presentation recognizable before the expanding Joker takes control of entire reels during the slot's separate Super Game.

Features & Win Potential

Expanding Symbols appear through the Joker Wild during Super Spins. When the Joker lands, it covers its entire reel and substitutes for regular paying symbols.

The Wild Symbol is restricted to the Super Game, which gives the qualifying win a clear mechanical consequence rather than merely changing the stake or display.

Bonus & Free Spins

The Bonus Game uses the captured base-game win as a meter for Super Spins, leaving the player to continue spending that value or collect it.
