How to cite

Slot Summary

Outer space supplies the setting for Star Spinner, but Blueprint Gaming keeps the underlying identity close to a traditional fruit machine. The stars have a practical role: their arrival can hold part of the reels through another spin. That connection between theme and reel behavior gives the game its character, alongside a separate Jackpot King feature.

How It Plays

Star Spinner evaluates matching line combinations from either end of the reels. Only the highest qualifying payout on each line is awarded, while wins across different lines are added together.

Mystery symbols can transform into other symbols after landing. Wilds appear on the middle reels and substitute when completing line combinations, with scatter and bonus symbols excluded from that substitution.

Bonus & Free Spins

A star on a middle reel expands to cover that reel and stays in place for a respin. Another arriving star also expands and holds, extending the sequence until a respin produces no new star.

In the Jackpot King version, overlay symbols provide access to a separate crown-collection round. Crowns move the award up a ladder, while icon reveals can continue the feature, collect its prize, or advance to Wheel King for a multiplier or progressive pot.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (96.47%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
