Shark's Bay Slot by Zillion Games

Two free spins modes, and the player picks which one. Three shark scatters open a selection screen where you choose between Wilds Wave and Bubbles Up - same number of spins, same Wild multipliers, but the Wilds walk in opposite directions. Wilds Wave pushes them horizontally across the reels between rounds, sliding from column to column. Bubbles Up floats them vertically, lifting Wilds upward through the rows each spin. Both modes use the same three Wild variants: a base Wild at 1x, a 2x version, and a 3x. When a multiplier Wild lands in a winning combination, that multiplier applies to the payout, so catching a x3 Wild mid-walk on a high-pay line is where the feature builds its peaks. Either mode runs 40x per entry through the buy option on the left side of the grid.

Both features also fire randomly in the base game. A wave animation sweeps Wilds across the grid horizontally, or bubbles rise from the bottom carrying Wilds upward - same directional logic as the free spins modes, just as one-off events on a single spin. It's the only base game modifier, but on a grid this size those random Wilds connect across enough ways to matter.

Bright cartoon ocean art with the waterline splitting the background - sky and clouds above, coral reef below. Pelicans, turtles, an octopus, and a crab fill the high and mid-pay tiers, each drawn in chunky animated style with thick outlines. The Wild is a blonde girl lounging on a pink inflatable ring, and the scatter is a grinning blue shark. Pink sea anemones and kelp border the golden reel frame on both sides, and the whole palette leans tropical - warm oranges, saturated blues, bright greens against the deep ocean behind the reels. More underwater playground than anything threatening, despite the shark branding.

No Hold & Ring, no jackpot wheel, no accumulated bonus meter. For a Zillion Games title that's a stripped chassis. The entire game runs on walking wilds and the dynamic way count - the Win Ways counter above the reels updates every spin based on how many symbols appear across each column, and on a 6x7 grid that number swings between a few hundred and the full 117,649.
