Alien Invaders at a glance
Alien Invaders activates reels when three matching symbols land along the bottom row. Every ten collected symbols adds +1x for that spin, while Free Spins keep the multiplier between turns.
Inside the game
How Alien Invaders works
Bottom-row matches switch reels on, active symbols feed a ten-count multiplier and Free Spins preserve that multiplier across the round.
The bottom row activates reels
Three matching symbols across the lower positions switch on the corresponding reels for the current winning combination.
Only active reels contribute
Symbols above an inactive reel cannot complete the same result, even when their artwork appears to match.
Ten symbols add +1x
The game raises the win multiplier for every ten collected active symbols during a base spin.
Free Spins keep the multiplier
After three or more scatters trigger the feature, multiplier progress remains available between individual turns.

What to look for in the demo
- Read the bottom-row activation first
Three matching symbols there activate the related reels. Upper symbols cannot contribute until their reels are active.
- Count symbols in groups of ten
Every ten collected symbols adds +1x for the current spin in base play. Watch the counter rather than estimating from animation.
- Value persistence in Free Spins
The bonus multiplier remains between feature turns, so early collection can improve the rest of the round instead of resetting immediately.

04 / The SlotsCollector take
A reel-activation game that makes the bottom row more important than the headline grid
Alien Invaders activates reels when three matching symbols land along the bottom row. Every ten collected symbols adds +1x for that spin, while Free Spins keep the multiplier between turns.
Alien Invaders uses five reels with three to five symbols visible on each, so the board height changes between reels as the symbols land and the bottom row remains the critical activation reference. Three matching symbols on the bottom row activate those reels and allow a paying combination to form. Every ten symbols collected raises the multiplier by +1x for that spin. Three or more Scatters open Free Spins, where the multiplier persists between turns rather than resetting after each result. That persistence is the main reason to reach the bonus: early progress can strengthen later wins. High volatility and a 5,000x maximum place the game below the giant ceilings of some Pragmatic releases, but it still needs sustained activation and collection to perform. Use the demo to read the bottom row first, then verify which upper positions are genuinely live. Players who enjoy unlocking a variable-height grid and building a visible counter should find the logic satisfying. Players who prefer every symbol to have immediate value may feel that inactive reels create too many decorative near-misses.
