Slot Summary

Making the bottom row decide which reels count turns each hit into a board-clearing event before Alien Invaders is even read as a Space slot. Pragmatic Play lets matching symbols activate their reels, explode, and feed a growing spin multiplier. Wild Multipliers and persistent Free Spins modifiers push the same idea further, while the 95.48% RTP and x5000.00 ceiling define its mathematical limits.

How It Plays

Every spin asks whether enough matching symbols have reached the marked bottom row. Once they do, the corresponding reels become active and all matching symbols there contribute.

Winning symbols then explode and leave gaps for replacements. Scatter explosions also remove adjacent symbols horizontally, vertically, and diagonally, widening the possible clear without using ordinary line evaluation.

Theme & Atmosphere

Sci fi, Space, and UFO themes turn the expanding reel field into an invasion scene, with each cleared group reading as resistance against the incoming symbols.

The subject remains playful rather than cinematic. Alien figures and spacecraft support the unusual bottom-row rule without obscuring which reels are active.

Features & Win Potential

Symbols collection tracks how many symbols explode during a spin. Every 10 cleared symbols raises the current multiplier by +1x before the round resolves.

Wild Multipliers join the total when a Wild reaches the bottom row. Bonus Bet supplies an optional route for changing access to the feature conditions.

Bonus & Free Spins

Three Scatter Symbols award 7 Free Spins, while each additional Scatter adds 3 more. Scatters reaching the bottom row can also award Additional Free Spins.

The Free Spins Multiplier persists between spins, and Wild Multipliers can reach 100x during the feature. That persistence gives later wins access to earlier multiplier gains.

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 (95.48%), with wins capped at its top multiplier (5,000×).

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.
