Sky Bounty

Sky Bounty is a sky-pirate slot from Pragmatic Play running on a 6x6 grid with 50 paylines. RTP 96.05% (95% and 94.03% operator variants available), high volatility (5/5), 5,000x maximum win. The central mechanic is a randomly sized square frame that appears on the grid: when a Kraken wild lands inside the frame, it expands to fill the entire frame. If more than one wild lands within the frame on the same spin, each adds to a growing multiplier applied to the total win.

In the base game, the frame appears randomly and its size varies. Free spins trigger on 3+ bonus symbols, beginning with 6 spins. During the bonus, the frame is persistent and grows each time an additional bonus symbol lands inside it — every new bonus symbol expands the frame's dimensions, increasing the area available for wild expansion and multiplier stacking. The combination of a larger frame and multiple wilds is the route to the 5,000x ceiling.

The expanding square mechanics create a visual session structure that differs from the standard PP bonus round. Base-game frame appearances can produce meaningful wins without a bonus trigger, particularly when the frame is large and multiple wilds fall inside it. That said, the 5/5 volatility means those moments arrive infrequently, and sessions that never trigger the bonus often close with minimal return.

The 96.05% RTP is at the lower end of the high-volatility PP range. Against structurally comparable slots — 6x6 grid, expanding-wild mechanic, 5,000x ceiling — it asks players to accept a slightly steeper house edge. The growing frame in free spins is the distinctive mechanic; players who value visual complexity over pure return efficiency will find value here.

Verdict
A growing frame mechanic on a 6x6 grid where multiple Kraken wilds stack multipliers. The 96.05% RTP is the honest cost. 5,000x ceiling.
