Gold Fish Slot by Light & Wonder

The hook is variety, and it comes in five colours. After almost any base spin a fishbowl can slide onto the screen and a single fish jumps in, each one a different reward, each one fired at random. Land the orange Gold Fish and you pick a bubble for a free spins count and a win multiplier to run alongside it. The Purple Fish blows bubbles that settle into a straight cash prize. Red Fish hands you a pick whose value keeps climbing every time the fish blows a "kiss". Green Fish gives a pick for one cash award, or an "Award All" tile that scoops every prize on offer at once. Blue Fish drops you into Superscatter spins, where every symbol pays from anywhere on the grid rather than along the lines. None of them announce themselves in advance, so the appeal is the not-knowing: which fish, which reward, how big.

Here's the catch, and it's a fair one to flag. All five of those randomly triggered rewards are powered by a mandatory Fish Feature Bet. Every spin quietly adds an extra ten times your per-line stake on top of the line bet, and you cannot switch it off. So each spin costs more than the line figure alone suggests, and you're paying for the chance at the fishbowl whether one shows up or not. Worth knowing before you set your stake.

There's a second, scattered route too. Land three or more Feature symbols and the Fish Food round opens as a pick bonus: you choose fish-food cans hunting three of a kind for an award, with a fourth match doubling it. Empty every can and it spills into a larger Turtle pick, with a Gold Turtle sitting at the top end of that.

The Wild fills in for everything bar the Feature symbol, and the whole thing plays out in a sunlit cartoon tank: light rays cutting through blue-green water, a pebble seabed, turtles and pink, blue and green fish drifting past coral and seaweed, with that grinning orange goldfish arched over the reels.
