Stars Awakening Slot by Playtech

The Giant Spin feature is the reason this one plays wider than its 20 lines suggest. It fires at random, with no scatter count and no trigger symbol to wait on, and when it hits a single oversized 3x3 block drops across reels three, four and five. That block is either one giant Star or one giant blue Wild Planet, and it's what pushes the game up to 243 ways to win on that spin, connecting matching symbols in bunches rather than along fixed lines. A giant wild block is the one you want, since it can leave a huge run of substitutes sitting across three reels at once.

The second feature works off your wins instead of a bonus symbol. On any winning spin the high-value aliens turn into Red Star scatters, which sets off the Supernova Scatters round, three escalating levels of reel respins with those scatters paying wherever they land. Fill the whole screen with Red Stars and it returns around 6,075x, the practical ceiling here. There's no separate free-games mode at all. The respins are the bonus, and both features grow out of a spin you were already going to make.

The base game leans on that blue Earth-like Wild Planet, which stands in for every paying alien and lands in full stacks, so a whole reel can turn wild in one drop. The paying symbols are cartoon alien astronauts in silver spacesuits, a grinning purple one, a green one, a blue female alien, a red officer under a peaked cap and a yellow one, sat above glowing red, orange and green planets and neon card royals. It all floats on a brown-and-purple nebula, with a column of five lit planet gems running down the left edge.

No jackpot hangs over any of it and there's no buy option, so everything comes off the reels themselves. It's a 2017 build, and the goofy cartoon aliens give it a lighter touch than most space slots bother with.
