Cows & UFOs Slot Overview

Cows and UFOs is a cartoon farm slot where the livestock are the payday and the aliens do the collecting. Endorphina kept the machine itself small: three reels, three rows, five fixed lines, a cabinet that would have looked at home in a bar twenty years ago. What runs on top of it is not small at all.

Cows and bulls land with cash values printed across them, and they sit there doing nothing until three of them show up together, one on each reel. That fires the UFO Alert round, and the farm gets picked clean. Everything worth having in this game happens inside that feature.

High volatility, 96.03% RTP, and a 30,000x ceiling only the bonus can reach.

Theme & Design

The setting is a moonlit farm: a magenta barn with a blue roof, a water tower up on stilts, hay bales stacked along a dirt road, a pickup parked by the treeline and a scarecrow in a floppy hat peeking up from the bottom corner like he knows something. Crop circles glow faint green in the field behind the reels. Every so often a saucer drifts in from the left with its beam down. The reels sit inside a little wooden shack frame with two lit lanterns hanging off the sides, a nicer touch than a 3x3 needed.

Symbols are chunky and cheerful rather than detailed: a cider barrel with two red apples, a leaning outhouse with grass at its feet, a pink pig grinning far too widely, a mailbox with a green letter sticking out. The wild is not a saucer at all but a red road sign with an alien face on it and a UFO plate bolted underneath, which is the best joke in the art. Cows arrive framed in red with their value stamped across the flank. The audio stays light, mostly crickets and cartoon squelches, and it never pretends to be sinister, which suits a sci-fi premise this daft.

Features & How They Work

Cows, Bulls and the prizes they carry

Every cow that lands shows a cash value worth the total bet multiplied by anything from x1 to x10. Bulls are the upgrade: x12, x14, x16, x18 or x20, same behaviour, bigger number. Neither pays on the spin that brings it in. They are stakes on the table, claimable only if the bonus fires, and the wild will not substitute for either of them.

UFO Alert Bonus Game

Three cows and bulls in any combination, one on each reel, and the farm turns into a 3x3 board holding nothing but cows, bulls, saucers and crop circles. The animals that triggered it stay put with their values intact. Three attempts on the counter to start; each spin costs one, and any new animal or saucer landing puts it straight back to three. Only the crop circle positions keep spinning. The round ends when the attempts run out or the board fills up, and every value on it is paid in one go. There is no retrigger, and the whole thing runs at the stake that started it.

Alien collectors and the multiplier

Saucers are the reason the round can go anywhere. When one lands, the cows and bulls near it that fail to hide get abducted, along with the little scientists riding inside any other saucer on the board, and all of those prizes are added into a single total before a multiplier of x1, x2 or x3 is applied to the lot. Green saucers hold two passengers, pink hold three. A pink saucer with x3 arriving late, after the board has already stacked up with bulls, is where the outsized results come from. A green one with x1 landing early is a shrug.

Risk Game

Endorphina's usual double or nothing card round. Pick one of four face-down cards, beat the dealer to double the win, up to ten times in a row. Jokers beat everything, the dealer never draws one, equal values push. It averages around 84% RTP, well under the slot, and that average hides a wide spread: a dealer 2 runs far above 100%, an ace sits near 40%. It is locked out during autoplay, and jackpot money cannot be gambled.

Mystery progressive jackpots

Three network progressives sit behind the game, GRAND, MAJOR and MINOR, awarded by random draw with no player input and no combination to chase. Larger stakes improve the chance of a draw, and the stake has to fall inside the allowed band to qualify at all. Plenty of operators switch the whole thing off, so it may not be there at all depending on where the game is loaded.

How Cows & UFOs Plays

Base spins go by fast. Three reels, five lines, nothing to adjust past the stake, and turbo makes them quicker still. The ordinary farm symbols pay so lightly that most spins register as neither a win nor a loss, and the game rather leans on that.

What holds attention is the cows. They drop in ones and twos constantly, each flashing a value in its red frame, each one worthless because nothing pays until a third arrives. Straightforward tease, and it works, though it can feel like being shown money the game has no intention of handing over. Long stretches pass with two on screen and the third reel landing a barrel of cider.

Then a third animal lands and the pace flips. The bonus is loud and easy to follow, swinging between about to end and just bought itself more time, sometimes twice inside the same round. Because it plays at the stake that triggered it, bet sizing carries more weight here than in a game with free spins, and trimming your stake mid-session probably costs more than it saves.

Pros & Cons

Pros

  • Cows and bulls show their cash value up front, so a trigger is worth a known amount before it happens
  • Collectors add prizes together before multiplying, which lets a 3x3 grid produce a serious single moment
  • Fast, uncluttered base game and a farm scene with real personality
  • Resetting attempts keep the bonus unpredictable instead of a flat three respins

Cons

  • No free spins and no buy feature, so waiting is the only route into the bonus
  • The ordinary farm symbols pay so little that base spins feel like filler
  • The Risk Game averages about 84% RTP, far below the slot itself
  • The progressive jackpots depend entirely on the operator and are often switched off

Is Cows & UFOs Worth Playing?

6/10

The premise carries this one further than the maths does. A 3x3 with five lines and no free spins is about as basic as a modern slot gets, and the standard symbols are filler, but the cash-carrying animals plus the collector saucers give the small grid something to build toward, and the abduction gag is drawn with enough care that the wait stays tolerable. Endorphina has made a pile of compact hold and win games; this is among the more charming ones.

The weakness is the gap between features. Nothing accumulates between rounds, no meter creeps upward, no counter tracking how close the third animal came, so a dry run is simply dry. And the Risk Game is a trap wearing the costume of an option. It is a one-feature slot that knows exactly what it is, which reads as refreshing or thin depending on how much patience came along for the session.

Frequently Asked Questions

How do you trigger the UFO Alert Bonus Game in Cows and UFOs?

You need three prize animals at once, one on each of the three reels. Cows and bulls both count and they can be mixed in any combination.

What is the maximum win on Cows and UFOs?

30,000x the total bet. It comes from the UFO Alert round, and it needs a board packed with bulls plus pink saucers landing the x3 multiplier, so treat it as the theoretical ceiling rather than a target.

What is the RTP and volatility of Cows and UFOs?

The RTP is 96.03% and the volatility is high. Operators sometimes run alternative RTP settings, so it is worth checking the figure shown in the game itself.

Is there a bonus buy or free spins round?

Neither. There is no buy feature and no free spins; the UFO Alert hold and win round is the only bonus, and it has to be triggered on the reels.

What age do you have to be to play Cows and UFOs?

18 or over, or whatever the legal minimum is in your country. The cartoon farm styling is deliberately playful but this is real-money gambling, so set a deposit limit before you start and stop when it is reached.
