Slot Summary

The 2023 release Gravity Bonanza places Pragmatic Play's cluster-pays formula on a 7x7 space grid, where each winning group disappears and new symbols fall. Its distinguishing idea is the Black Hole: it collects one paying symbol type across the spin and calculates that separate award when the tumble sequence ends. Free Spins can add random multipliers to the same collection mechanic.

How It Plays

The 7x7 Grid pays clusters of at least 5 matching symbols connected horizontally or vertically. Winning symbols disappear, and replacements tumble into the cleared positions.

A Black Hole may select one paying symbol type for collection. Matching symbols present across that spin's successive Cascading results contribute to a separate closing award.

Theme & Atmosphere

Space and Sci fi define the setting, with the Black Hole converting a familiar cosmic object into the central collection device rather than mere background imagery.

The Action & Adventure treatment comes from the oversized grid and repeated collapses, while the presentation keeps the collection total distinct from ordinary cluster results.

Action & Adventure Space Sci fi

Features & Win Potential

Cluster Pays and Cascading work together: a qualifying group clears, new symbols enter, and the Grid is checked again until no further cluster forms.

During Free Spins, Random multiplier values can attach to the collection result. The listed Multiplier possibilities are x2, x3, x5, and x10 for qualifying spins.

Bonus & Free Spins

Free Spins trigger from 3 or more Scatter symbols, with larger Scatter counts awarding more spins. The round retains Cascading and can apply a Random multiplier to the collected-symbol award.

Bonus Buy provides direct access to Free Spins for 100 times the selected bet, while the standard trigger remains available through Scatter symbols in regular play.

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 (96.09%), with wins capped at its top multiplier (10,000×).

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.
