Galaxy Miner Slot by PG Soft

The Win Vortex symbol is a black hole with an amber corona, and it comes with a counter - anywhere from 1 to 5. When it lands alongside Prize symbols (asteroid rocks carrying values from 0.5x to 1000x), it burns one counter to collect every Prize value on the grid. If counters remain, it collects again. Same Prize symbols, same values, collected multiple times in a single spin. A Win Vortex with 3 counters sitting next to two Prize symbols worth 50x and 100x pays (50 + 100) x 3 = 450x. No wilds, no scatters, no paylines. The entire base game runs on whether a Vortex and Prizes show up together, and how many counters the Vortex carries when they do.

Six or more Prize symbols in one spin trigger the Bonus Feature, and the mechanic gains a second layer. A Persistent Win Vortex locks into the center of the grid - middle row, second reel - and stays there for the duration. It collects every Prize value on every single bonus spin, no counters needed. Three spins to start, resetting to three each time a new Prize or Win Vortex appears. Regular Win Vortex symbols still show up during the bonus, and they work the same way - burn counters, collect Prizes. But once a regular Vortex runs out of counters, its accumulated total gets absorbed by the Persistent Vortex too. So Prizes feed into Win Vortexes, Win Vortexes feed into the Persistent Vortex, and the center position snowballs. Win Vortex symbols that have collected values stick on the reels until the bonus ends, which means the Persistent Vortex keeps pulling from them spin after spin.

A hulking yellow mining vessel drifts through an asteroid field against deep-space blues and purples, a glowing black hole pulling debris into its orbit below. The Prize symbols are chunks of grey rock studded with green crystal formations - jade-colored, angular, like raw emeralds embedded in stone. Empty positions show smaller dark asteroids tumbling through the void. The whole game is built in portrait orientation with a sci-fi cockpit UI framing the grid in gold and teal metalwork, status lights blinking along the top border. It's a surprisingly layered collection loop for a 3x3 grid, with about half the total return concentrated in the Bonus Feature and base game hits landing roughly one in ten spins.
