Gravity Bonanza is a high-volatility 7×7 cluster slot where Black Holes collect one selected symbol through a tumble sequence and can multiply the final Gravity Bonus in free spins.
The collect mechanic can pay beyond normal clusters, but strong value needs many selected symbols before the tumble sequence ends.

How Black Holes collect symbols
Five or more matching symbols connected horizontally or vertically create a cluster win on the 7×7 board. Winning symbols disappear, replacements fall into the cleared cells, and the same paid spin continues while additional clusters keep forming.
When a Black Hole appears, it selects one regular symbol and collects every matching instance visible during the complete tumble sequence. After the sequence ends, the collected quantity is evaluated as a separate Gravity Bonus cluster payout.
Three to seven scatters award progressively more free spins, and the round can be retriggered with additional scatters. Black Holes can carry 2x, 3x, 5x or 10x multipliers that increase the collected-symbol payout.
Main gravity bonus features
- 7×7 clusters: Five connected symbols trigger a payout and start the tumble mechanic.
- Black Hole selection: The feature chooses one regular symbol type to collect during tumbles.
- Sequence collection: New matching symbols are added until the current tumble chain ends.
- Gravity Bonus: The final collected count pays separately according to cluster values.
- Bonus multipliers: Free-spin Black Holes can apply values from 2x to 10x.
- Feature retriggers: Additional scatters can extend an already active free-spin round.
Who may enjoy collect mechanics
- Collection mechanics: You enjoy a second payout calculation running alongside cluster wins.
- Large-grid tumbles: You prefer connected groups and repeated cascades on a 7×7 board.
- Bonus multipliers: You like a feature where collect values can receive a separate boost.
- Wide stake ranges: You want selectable bets extending from $0.20 to $240 per spin.
A Black Hole may appear without gathering enough symbols for strong value.

Free spins and payout ceiling
Base-game value is split between ordinary cluster payouts and the final Gravity Bonus. Long tumbles can help both sides because they create repeated clusters while giving the Black Hole more opportunities to collect its selected symbol.
Free spins improve the collect side through Black Hole multipliers, and retriggers add more attempts. The multiplier affects the collected-symbol award rather than guaranteeing a large cluster, so a high value still needs a substantial collection.
The x10,000 ceiling can come from an exceptionally large symbol collection or a strong multiplied Gravity Bonus supported by productive tumbles. Reaching the upper range requires the selected symbol to recur repeatedly before the sequence closes.
