Wild Dolphin Slot by GameArt

The wild here is a smiling bottlenose dolphin, and it lands stacked. So when it shows up it tends to arrive in a column rather than alone, and a single reel can fill top to bottom with dolphins in one drop. It subs for every symbol except the pearl, which keeps the trigger logic clean: dolphins build line wins, the pearl handles the bonus. With dolphins covering a whole reel, the ten lines running through that column all read it at once, and that's where most of the bigger base hits come from.

Triggering the bonus is the standard route. Land three, four or five pearls (each one resting in an open clam shell) anywhere on the grid and you're into 15 free spins. The hook is a flat x3 on every win for the whole round. Not a building multiplier, not a random ladder, just a clean triple applied to anything that pays while the spins run. Combine that with a stacked dolphin dropping into the round and a single good spin can land at three times its normal value. The pearl still pays as a scatter on the way in, then steps back once the spins start.

Visually it's a calm tropical reef. The reels float in clear sunlit water over a coral seabed, light shafts angling down from the surface, bubbles drifting up past a chrome-and-gold logo overhead. The pays are all sea life rendered in bright ocean colour: an orange clownfish, a red-and-white lionfish, a puffed pufferfish, a purple seahorse, a green sea turtle, with gold-and-jewel card royals filling the low end. It sits squarely in the underwater bracket alongside the older Dolphin's Pearl school of slot, which is plainly the template this one is built on.

Outside the dolphin wild and the pearl bonus, there's a card gamble after any win, double or take, and that's the whole feature list. No buy option, no jackpot, no second bonus tier. It's one of GameArt's earliest releases and it shows: the 2,778x ceiling is modest by any modern standard, and a single flat-multiplier free spins round is a thin spread for a session. If you want the dolphin to pay big, you need it stacking inside those 15 spins. Anything short of that and the reef stays pretty quiet.
