How to cite

Slot Summary

The 5x3 field gives Alien Invasion 243 adjacent-reel ways to connect symbols, with the main swing reserved for resettable Free Spins. KA Gaming starts that round with 3 spins; any win resets the count, raises a shared multiplier and can keep the sequence alive. A Chance Rescue Spin may turn the third reel wild on the final chance, making survival within the feature the game's defining win path.

How It Plays

A paid round checks matching symbols across adjacent reels from left to right, producing 243 Ways without requiring symbols to sit on preset lines.

The main feature changes the objective from completing a fixed allotment of spins to preserving the round. Each qualifying win replenishes the remaining count and improves the multiplier.

Theme & Atmosphere

Sci fi and Space define the setting, with an extraterrestrial invasion presented through alien creatures, advanced equipment and a remote planetary environment.

The Futuristic subject is sharpened by Guns, UFO and Action & Adventure imagery, giving the bonus rescue event a direct conflict-based context.

Action & Adventure Space Futuristic UFO Sci fi Guns

Features & Win Potential

The 243 Ways system evaluates adjacent-reel combinations, while the Wild Symbol can replace ordinary paying symbols when it lands in a useful position.

Scatter Symbol landings open Free Spins. Within that round, wins can award Additional Free Spins through the reset rule and increase the accumulating return multiplier.

Free Spins Scatter Symbol Wild Symbol 5 Reels 243 Ways Additional Free Spins RTP range 96% RTP

Bonus & Free Spins

Three or more Scatter Symbols trigger the Free Spins feature with 3 spins. Every win resets the remaining total to 3 rather than adding a fixed amount.

If the final attempt does not win, a rescue event may turn the third reel into a stacked Wild Symbol, potentially preserving the feature through another payout.

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 (Medium). The model is calibrated so the average return equals this slot's published RTP (96.00%), with wins capped at its top multiplier (1,000×).

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.
