Sky Bounty Slot by Pragmatic Play

A variable-size frame - starting at 2x2 and capable of growing to 6x6 - appears at random during base game spins. Any wild that lands inside the frame expands to fill the entire area. If multiple wilds land within the same frame, their multiplier values stack. At base size, this is a modest boost. At full size, the frame covers the entire grid.

The free spins round awards 6 spins, with the frame moving to a new random position each spin. Collecting 3 scatter symbols grows the frame by one tier and adds 2 extra spins. Since the frame persists and expands throughout the bonus, late-round spins with a large frame and stacked wild multipliers carry the most weight. The Kraken wild substitutes for everything except the bonus scatter.

Fifty paylines across the 6x6 grid create steady small wins from pirate-themed symbols - cannons, compasses, crossed swords, and gems in six colors. The background depicts an airship battle in the clouds, and the entire grid sits inside a weathered ship deck frame.
