Gravity Bonanza

Gravity Bonanza is a space-themed cluster slot from Pragmatic Play. Matching symbols that touch horizontally or vertically win on a large square grid, then disappear so new symbols can cascade from above. The standout element is the Black Hole, which can appear on the grid and sweep away every symbol of a randomly chosen kind, awarding a cluster prize for them.

Scatters trigger the Free Spins round, and further scatters during the round can extend it. In the bonus, Black Holes can carry multipliers that apply to the prize they award, so a well-timed sweep across a symbol that fills much of the board can stand out. The animation gives each spin a focal point that standard cluster games often lack.

It may suit cluster fans who like a sci-fi look and a feature that acts on the whole board. Some sites run different RTP settings, so the info screen is worth checking. The free demo uses play credits only, and every result is random.
