Over The Moon Slot by Big Time Gaming

Up to three rockets park beside the reels, each stamped with a x1, x5 or x10 multiplier in the base game. They don't pay on their own. What they do is wait for a Meteor. Every Meteor symbol that lands reveals a cash prize worth up to 100x your stake, and that prize is paid once for every rocket currently on screen, each copy multiplied by the number on its rocket. Three rockets sitting on x10 turn a single meteor into ten times that value counted three times over, and that stacking is where the big money comes from.

The catch is fuel. Each rocket carries fuel cells that burn down as you play. After every reaction a rocket showing no lit cells gets scrapped, and the survivors each lose a cell, so a rocket is on a countdown from the moment it appears. Battery symbols are the lifeline. Each one tops up every rocket on screen by three cells, keeping the multipliers alive long enough to actually catch a meteor. Reactions drive the whole loop: winning symbols clear out (Scatters aside), fresh ones drop from above, and the chain keeps running while anything pays, ticking another cell off your rockets each time. Everything wipes back to empty when the base game ends.

Three or more Scatters open 12 free spins, with 2 more for every Scatter past the third, and the round retriggers on the same terms. The version you want is the enhanced one. If any triggering Scatter is a Megascatter, those 12 spins run with rocket multipliers that start at x2 and climb by x2 for every rocket that shows up, so instead of stopping at x10 the numbers keep stacking as long as rockets keep arriving. You can also skip the wait and buy the feature outright, with Feature Drop symbols knocking the price down when they land.

The reels sit inside a rounded chrome porthole against a turquoise-and-purple galaxy full of twinkling stars and nebula haze, a red-and-white cartoon rocket looping the logo up top. Paying symbols are glossy faceted gems, purple leading the pay table, then red, blue and green, over the usual card royals.
