How do the free spins in Alien Invaders work? Keep it simple.
Triggered by 3+ SCATTER symbols across a base spin (including its tumbles): awards 7 spins, +3 per SCATTER beyond the third. Each reel starts at 3 symbols for the round and may grow by 1 (up to 5) after any spin, then holds that size. WILD multiplier range widens to 1x-100x (vs 1x-25x in the base game). A SCATTER reaching the marked row during the round retriggers +1 spin. Win Multiplier persists across the whole round.
