Slot Summary

An anxious farm under a passing UFO gives Cows & UFOs its comic premise. Endorphina compresses the idea into a 3x3 game with 5 fixed paylines, a 96.03% RTP, and high volatility. The small format is not the main destination: cows and bulls lead toward UFO Alert, where abductions, collected prize values, and a random multiplier carry the x30000.00 ceiling.

How It Plays

Each spin resolves on three reels and five fixed lines, so outcomes remain easy to scan. Ordinary line wins belong to the main game before the cattle trigger appears.

The Wild dog substitutes for regular symbols but not cows or bulls, and it appears only during base play. That restriction separates UFO Alert from normal line wins.

Theme & Atmosphere

Farm and Space themes collide through cattle abductions, suspicious UFO activity, and secret alien experiments. The Humor comes from treating an ordinary pasture as a recurring extraterrestrial incident.

Animals remain part of the mechanics rather than mere decoration. Cows and bulls trigger the special round, while the farm dog serves as the base-game Wild.

Features & Win Potential

The optional Risk Game sits after qualifying wins as a separate gamble choice. It changes the handling of an existing payout rather than helping trigger UFO Alert.

Random multipliers matter inside the collector sequence, where abducted prize objects are pooled before the UFO multiplier is applied. The final accumulated total determines their effect.

Bonus & Free Spins

Three cows or bulls appearing across all three reels trigger UFO Alert. The feature changes the main reels into a 3x3 grid containing cattle, UFOs, and crop circles.

During the round, UFOs abduct prize-bearing cattle and combine their values. The selected UFO then applies an x1, x2, or x3 multiplier before the award is paid.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.03%), with wins capped at its top multiplier (30,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
