Star Supreme

Greentube keeps 362 titles in our index, and this August 2021 release shows the studio at its plainest. Fruit symbols under star framing. The dressing is old-fashioned, the distribution behind it is not, and our feed records a return of 95.10% that no second source has yet matched.

Fixed lines, a level-5 grade and a 16,800x ceiling

Five reels turn, the paylines are fixed, and no line-count choice is offered before a spin. Nothing else is bolted on. Our mechanics table comes back negative on every modern addition we track — no Megaways licence, no purchase shortcut, no pooled jackpot, no tumbling symbols — which leaves ordinary symbol hits doing all the work. Variance reads 5 out of 5. Placed against the 96.08% median we compute from 9,233 games with published return figures, that 95.10% falls just under a full point short, while the top prize is listed at 16,800x the stake, a number only the severe end of the variance scale can support.

Long dry stretches are the price of admission for anyone drawn to that ceiling. Bet limits are missing from our feed. Steady, small returns are not what a 5-of-5 grade produces, so read the rating as a warning.

The 4.90% the house retains is written into the maths rather than caused by a cold run; decide a spending ceiling before the reels move, and remember access is 18+.
