Cows & UFOs Slot by Endorphina

A moonlit countryside at night, and something is wrong on the farm. Cows & UFOs sets its little three-reel cabinet right in the middle of a cartoon farm scene, deep night blues and greens behind a red barn, a water tower, hay bales and a parked pickup, with glowing green crop circles burned into the field and a saucer hovering off to the left, beaming light down. The reel symbols match the world: barns, tractors, sheep, pigs, chickens and mailboxes, plus a green alien UFO icon that acts as the wild and a spotted cow that wears its own cash prize stamped across it (you'll see values like EUR 0.05 or 0.20 sitting right on the symbol). The board is small, just five fixed lines, so base spins are tight and the UFO wild substitutes for everything except those cash cows and bulls.

The cows and bulls don't actually pay during normal spins. They carry a value, sure, a cow worth your total bet times anywhere from 1x up to 10x, a bull worth 12x, 14x, 16x, 18x or 20x, but you only collect those numbers once you're inside the bonus. Land three of them across all three reels at the same time and the UFO Alert round fires, dragging the triggering animals (prizes and all) onto a fresh 3x3 grid of cows, bulls, UFOs and empty crop circles.

It's a hold-and-win at heart. You start with three attempts, each spin burns one, but any animal or UFO that lands resets you back to three, and only the crop-circle cells keep spinning while everything else locks. Where it gets genuinely odd is the UFO collectors. Each UFO that lands carries alien scientists, and they abduct the cows and bulls nearby. Every prize that boards a single saucer, cows, bulls and scientists ferried over from other UFOs alike, gets added up, then multiplied by that UFO's own value of 1x, 2x or 3x. Green saucers hold two abductees, pink ones hold three, so a pink UFO swallowing a fat bull and a couple of high cows is exactly the result the whole round is chasing. It runs until your attempts hit zero or the grid is completely covered, then totals everything and pays once.

There's no way to buy the bonus and no retrigger, so the only entrance is landing those three animals on a real spin. Wins can be pushed through a card gamble, double-or-nothing up to ten times in a row, and the game also feeds three network progressive mystery jackpots (Grand, Major, Minor) that drop at random with no input from you. The 30,000x top end is steep for a five-line machine, and it lives almost entirely in that pile-the-prizes-onto-a-tripled-pink-saucer moment, not in the quiet base game.
