Gunpowder

Gunpowder by Yggdrasil is a high-volatility video slot with a pirate/naval warfare theme, set on a 5×3 reel grid and offering 10 fixed paylines. Wilds appear in the form of phantom pirate ships that become sticky and trigger respins when they land, remaining locked in place while the rest of the reels spin. The Phantom Power feature can trigger randomly in both the base game and during Free Spins: when a Wild appears, it ‘battles’ surrounding high-value ship symbols, converting them into additional Wilds if it wins, and awarding extra respins or multipliers. Free Spins are triggered by landing three or more Scatter symbols (treasure chests), which award 10, 12 or 15 free spins depending on whether you get 3, 4 or 5 Scatters. During Free Spins all Wilds stay locked (sticky), and if you manage to land at least one Wild on each reel you receive 5 additional spins. Wilds during Free Spins may also carry multipliers of 2x or 3x, amplifying their effect. There also is a Golden Bet option: paying extra increases the chances of triggering Sticky Wilds and the Free Spins feature. A Feature Buy allows players to buy directly into the Free Spins round, receiving between 7 and 12 free spins immediately. Gunpowder also offers a top win potential of about 10,000× the bet through combination of sticky Wilds, multipliers and retriggers.
