Catch the Wind Bonus Buy Slot by Evoplay

Seven ships to fill a meter, three completions max, and then it shuts off. That collection system separates the free spins here from a standard walking wild bonus. Every Captain's Ship that lands during the bonus starts at x1 and shifts one reel left per spin, picking up +1 to its multiplier with each step. A ship entering on reel 5 exits reel 1 at x5, then drops into the collection bar at the top. Hit seven collected ships and you get another batch of spins - but only three times before the meter locks permanently.

Ships still on the grid when a collection completes carry over into the next cycle, so late-landing ships from one round feed directly into the next. Multipliers on the same payline add together (two x3 ships give x6, not x9), and that stacking gets interesting when three or four walking wilds overlap on adjacent reels during the final spins of a collection run. The 50x buy option gives 8 spins, 72x gets 10, and 98x starts 12 - higher tiers place more ships on the reels at the start, giving the collection a head start rather than just adding duration.

Warm-toned cartoon pirate art against open turquoise water, with five character medallions as the premium symbols and faceted gemstones in purple, red, teal, green, and gold filling the low end. The wooden reel border sits directly over the ocean - no beach, no cave, just open sea and a couple of distant palm-topped islands. Base game wilds carry x1 to x3 multipliers even outside free spins, which keeps the 20 paylines from feeling too flat between triggers.
