Lucky Waterfalls Slot by BigPot Gaming

Free spins award 8, 15, or 30 rounds depending on scatter count, and the moment the round begins, Extended Fixed Wilds drop onto reels 2 through 5. Each one stretches to fill its entire column and stays locked there for every remaining spin. So if two reels get covered at the start, those two columns are solid Wilds for the whole round - 8 spins minimum with two full substitute reels already in place. Three columns would leave almost nothing uncovered across the 20 paylines. The Wilds don't accumulate spin by spin or reset; they're assigned once at the start and hold until the round ends. A buy option on the left side of the grid skips the scatter chase entirely, though the price isn't listed anywhere in the game's info panels.

Outside of that bonus the base game is plain. Standard left-to-right paylines, a mermaid Wild that substitutes for everything, and scatter symbols decorated with palm fronds and bright pink lettering. The whole game sits inside a dim cave with water pooling at the bottom of the screen and rock walls closing in on both sides. Teal and aqua tones dominate - the card symbols (10, J, Q, K) look like they're carved from ice, translucent blue with cracks running through them. Higher up the paytable, a faceted water-drop crystal catches light against the dark background, a koi fish twists mid-jump, and pink lotus flowers float next to a duck hatching from a cracked egg. The mermaid Wild has red hair and sits in a golden border that glows warmer than anything else on screen, pulling focus to whatever reel she lands on. Rocky overhangs and dripping stalactites close off the top of the grid, keeping the whole scene boxed in and damp.
