Space Collector Slot by PoggiPlay

Nineteen paylines on a 5x3 grid, a Pick a Line bonus, and a fuel collection mechanic that feeds directly into free spins. The whole game loops around that connection. Land enough Scatters to trigger the bonus round and you're presented with a line-picking mini-game where each pick adds Space Fuel to your reserves. That fuel converts into x2 multipliers during the free spins that follow. More fuel collected, more multipliers active when the spins start counting.

The multiplier display sits at the bottom-right near a stubby white rocket on a launch pad - it reads X1 during base play and scales up through the bonus chain. Symbols are 3D-rendered alien resources floating against teal-green planetary hills and a starfield: copper spheres trailing pink antennas, green metallic clusters, purple crystal formations, gold orbs, blue mechanical drones that look like tiny solar panels, and pink coral growths. A cartoon astronaut stands to the left of the grid, watching. The Wild is a purple badge stamped with the game logo and substitutes for everything except the Scatter, which is a green circuit-patterned sphere. Nothing unusual about the base game payout structure - standard left-to-right line wins.

No buy bonus, no jackpot, no ante bet. At 1,808x max win with medium volatility, the ceiling is modest and the path to it runs entirely through that fuel-to-multiplier pipeline in the bonus round. Space-themed slots tend to lean on flashy visuals over mechanical depth, and this one fits that pattern - the bonus concept is neat but the base game offers little beyond standard spins while you wait for Scatters.
