SlotRanker Score: 76 — Cosmic Heart by High 5 Games

How to cite

Slot Summary

A reel grid topped by an orbiting reward belt makes Cosmic Heart a slot about watching opportunities move between spins. High 5 Games connects that movement to its space setting: the Prize Line keeps potential rewards visible above the action, giving the game a persistent point of interest beyond the next symbol combination.

How It Plays

At the start of a bet, the Prize Line moves left above the reels. Landing a Cosmic Heart symbol activates the reward currently positioned above that reel.

The moving belt can offer credits, multipliers, wilds or bonus entry. Because its rewards occupy different reel positions as it moves, the relevant target changes between bets.

Bonus & Free Spins

The free-games reward displays the number of spins it grants. If multiple free-games symbols activate together, their displayed awards combine into the allocation for the bonus round.

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 (High). The model is calibrated so the average return equals this slot's published RTP (96.00%), with wins capped at its top multiplier (10,174×).

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.
