Galaxy Miner has nine positions, no lines, no ways and no regular symbols. Most cells show empty dark rock; the rest are asteroids with a cash value and, now and then, a black hole called the Win Vortex. A prize only pays if a vortex is on the grid to swallow it. PG Soft released this space-mining slot in July 2025. In 100 demo spins at 12.00 only ten spins paid, but three of them came within four spins of each other: 288.00, 240.00 and 240.00.

How the Win Vortex pays
A vortex carries one to five counters, shown as dots under it. When it lands with prizes, it uses one counter to collect the value of every prize on the grid, then uses the next counter to collect them all again, and so on until the dots run out. Only then is its total paid. Several vortexes each collect separately.
Spin 16 was a clear example. Three purple crystals on the middle reel, 36.00, 24.00 and 36.00, made 96.00, and the vortex beside them had three counters. It collected 96.00 three times.
That made 288.00, or 24 stakes, from crystals near the bottom of the prize scale.
Two more in quick succession
The very next spin had two red ores of 120.00 and a vortex with a single counter, which collected them once for 240.00.
Two spins later a gold nugget of 240.00 landed with a single-counter vortex, and the result was the same, 240.00.
Prizes without a vortex are lost. Most of my losing spins looked like that: asteroids on the grid and no black hole to collect them.
The bonus round
Six or more prize symbols in a single spin start the Bonus Feature. A permanent vortex is placed in the centre of the second reel, and the round works like a hold-and-win: three spins, reset by every new prize or vortex. The permanent vortex collects every prize on each spin, ordinary vortexes keep the values they have collected, and when their counters run out the permanent one absorbs them as well. I never had six prizes at once, so this follows the rules.
One good run in a hundred
I put 1,200.00 into the demo and took out 924.00, ending on 99,724.00. Spins 16, 17 and 19 made 768.00; the other seven wins were 24.00 twice, 12.00 twice, 18.00, 30.00 and 36.00. After spin 19 the balance stood 588.00 up, and 81 spins with five small wins took all of that and more.

Asteroids and black holes
The grid is three reels by three rows. Prize symbols come in four colours, and each carries a cash value set as a multiple of the bet.
| Asteroid | Value | At 12.00 |
|---|---|---|
| Gold nugget | 20x to 1,000x the bet | 240.00 to 12,000.00 |
| Red ore | 5x to 15x | 60.00 to 180.00 |
| Purple crystal | 1.5x to 3x | 18.00 to 36.00 |
| Green rock | 0.5x to 1x | 6.00 to 12.00 |
The demo's opening screen shows a gold nugget marked 12,000, the 1,000x top value at this bet, between two red ores of 180.00. The largest nugget in my session was worth 240.00, the 20x minimum.
Grimms' Bounty: Princess & the Frog has a collector too, a frog that multiplies the coins instead of collecting them several times.
