A black hole in Gravity Bonanza removes every copy of one random symbol, pays the resulting cluster value and opens space for another cascade. During free spins it may also carry a multiplier up to 10x. The feature is thus both a collector and a board-clearing device, with its usefulness determined by which symbol is selected.

| Main features | Five-symbol clusters cascade. A black hole removes every instance of one random symbol, pays its cluster value and creates further tumbles. Three scatters start free spins, with up to fifty initially; bonus black holes can carry multipliers up to 10x and later scatters retrigger. |
RTP and stake limits can vary by version and market. Check the information screen in the game you open. Maximum win is a ceiling, not an expected result.
Clusters around a destructive collector
The 7×7 space grid requires five or more identical neighbours. Winners disappear and new icons fall from above. A black hole can gather all occurrences of one randomly chosen icon, settle its cluster prize and remove those symbols to produce further tumbles.
Selection matters more than the animation. A board containing many copies of the chosen icon gives the black hole more to collect, while a sparse symbol creates less immediate value and fewer empty positions. The subsequent cascade is another opportunity, not an award guaranteed by the removal itself.
Bonus black holes gain multipliers
At least three scatters trigger free spins, with larger entries able to award as many as fifty turns. In the bonus, black holes can arrive with multipliers up to 10x and apply them to the random symbol being collected.
Three or more scatters can retrigger, extending the window for multiplied holes and cascades. Extra duration, symbol count and the attached multiplier all influence different stages. A 10x hole still depends on a useful selected icon, while a long allocation cannot ensure another hole arrives.
A low-RTP reference configuration
Released on 28 September 2023, Gravity Bonanza is listed with 95.07% RTP, medium volatility and a 10,000x maximum. The 95.07% figure is specific and should not be normalised to a common provider RTP.
The black hole communicates collection and removal through one clear event, which is the design’s strength. Its limitation is random targeting: the selected symbol may not be abundant or well placed. Readers who enjoy chain reactions can follow the resulting space easily, but progress does not persist as one guaranteed meter.
Gravity Bonanza gives its cosmic object two linked jobs. The black hole converts a chosen symbol population into a cluster award and then changes the board by removing it; bonus versions can multiply that collection. Free spins and retriggers create more attempts, yet the selected icon and multiplier remain random. This produces a strong cause-and-effect cascade without guaranteeing that every hole is valuable. The 10,000x ceiling and medium-volatility label need to be considered alongside the exact 95.07% reference RTP for this standard release.
