Big Blue Fishing Slot by Genii

Picture a calm tropical reef with a yacht idling on the horizon - that's the backdrop here, and the cabinet sits underwater with coral on the floor and rocky cliffs flanking either side. Symbols swim into place as cartoon marine life: a leaping blue marlin trailing white spray, a hungry shark, a yellow tuna mid-snap, an angry pufferfish, a magenta jellyfish, plus royals A through J built from coral with bubbles drifting around them. The "MAX WAY" tag under the logo signals what matters - this is a 243-ways engine, not paylines, so adjacent matches from the leftmost reel pay regardless of position.

The Wild does the heavy lifting in the base game. It substitutes for everything except the two scatters and doubles any win it joins, which keeps spin-to-spin volatility ticking along even without the bonuses. There are two separate scatters, and that distinction is the part most players miss on a first read. One scatter handles Free Spins: 3 land 6 spins, 4 land 10, 5 land 15. No retriggers, no multiplier upgrades, just clean rounds at the triggering bet.

The other scatter is where the game gets interesting. Three or more Feature symbols launch a Hold-and-Respin round that runs on its own clock. You start with 3 spins. Every Feature symbol on screen sticks. Every new Feature symbol that lands resets the counter back up, and an Extra Spins symbol top-ups the counter directly. When the spins finally run out, every held Feature symbol flips to reveal a prize value scaled to the bet that triggered the round - so the round only pays out at the end, not as you go. One catch worth flagging: this Feature can't be triggered inside Free Spins, so the two bonuses stay separate.

Top win is 21,800 coins, which works out to roughly 218x at default stake - modest by 2020s standards, but the Wild x2 means decent base hits land more often than the headline suggests. No buy bonus, no jackpot ladder, no fishing-style pick-the-catch round despite the theme. The Hold-and-Respin is the closest this game gets to a money-shot mechanic, and it's the one worth waiting for.
