Star Supreme: Greentube's Fruit-and-Stars Throwback

Star Supreme is a Greentube (Novomatic) slot that dresses a familiar fruit-machine cabinet in a cosmic coat of paint. Glowing stars sit alongside classic fruit symbols on a five-reel grid, and the whole game leans on one idea rather than a stack of gimmicks: a shifting highlighted reel position that decides when the bonus round fires. It is a compact, high-volatility release aimed at players who want a clean line-pays slot with a single, well-defined feature to chase.

How Star Supreme Plays

The action runs across five reels with 50 fixed paylines, so every spin stakes the full set of lines and wins are read left to right from the leftmost reel. Symbols mix traditional fruit icons with higher-value bells, sevens and the game's red-haired Joker. There are no cascading reels, no buy-feature button and no ways-to-win maths here; the design deliberately keeps the base game readable and lets the bonus carry the excitement.

The Joker Wild

The Joker is the wild, and it substitutes for every symbol except the Star scatter. Crucially, the Joker can appear stacked across a reel, which is what turns an otherwise quiet spin into multiple connected line wins at once. In the base game this stacking is the main source of bigger hits, so seeing a reel fill with Jokers is the moment to watch for.

Highlighted Position and Free Spins

Star Supreme's signature mechanic is the highlighted position. Highlighted fields appear on all reels, and the bonus triggers when the Gold Star scatter lands on a highlighted field. The free spins round is triggered when the Star scatter lands on that highlighted cell, rather than just anywhere on the grid, which gives the base game a constant sense of anticipation as the glowing spot moves into a more promising row.

Once the round begins you start with a set of free spins and a win multiplier that increases by one with every winning combination. The multiplier has no fixed cap, so a clean run of consecutive wins is what builds the round into something substantial. Landing the scatter again on the highlighted position during the feature can extend it further, keeping the multiplier alive.

RTP and Volatility

Star Supreme runs at a 95.1% RTP, which sits a little below the modern average, so it is best treated as a feature-chasing game rather than a grind-it-out session. The volatility is high. Expect the base game to run cold between bonuses, with the real value concentrated in the free spins and that escalating multiplier. Patience and a session bankroll suited to dry spells matter more here than they would on a low-variance fruit slot.

Theme and Presentation

Visually the game keeps things simple: bright fruit and star symbols set against a dark, starlit background, with the clean reel layout and crisp jingles you would expect from a Novomatic land-based-style title. It is functional and uncluttered rather than cinematic, which suits a slot built around one core feature. The shifting golden highlight is the most distinctive visual touch and doubles as a useful at-a-glance cue for how close you are to a trigger.

Who Star Supreme Suits

This is a slot for players who like classic line-pays gameplay with a clear hook. If you enjoy stacked wilds, a single escalating-multiplier bonus and the tension of waiting for a scatter to drop on exactly the right spot, Star Supreme delivers that loop cleanly. Players who prefer frequent small wins or feature-packed modern mechanics may find the base game too quiet for their taste.
