Fish Trio Slot by Playtech

Three glass fish bowls sit above the reels, and they're the reason to load this one up. A blue fish labelled BOOST, a red one labelled MULTIPLY, a green one labelled COLLECT. Each is tied to a coloured coin, and none of them does a thing until the respins start. Land a coloured coin in the base game, or three or more Bonus symbols, and the Underwater Respins kick off.

The round splits the screen. A bottom array takes only Cash, Coloured and Mystery coins, while the top array is where the fish do their work. You open with 3 respins, and the counter is forgiving, every Cash or Mystery coin that lands locks in place and hands the count straight back to 3. Keep coins dropping and the round keeps running. Cover all 15 positions and the Grand pays 1,000x the bet.

A coloured coin sticks on its reel and waits. When a Cash or Mystery coin lands on that same reel, the coin fires its effect, then spins away on the next respin. Red multiplies every Cash and Mystery value on its reel by 2x, 3x or 5x. Green collects them all and pays the total. Blue boosts them by its own value. Three Bonus symbols award one fish, four award two, five turn on all three, and they stack, so a green Collect firing after a red Multiply on the same reel gathers the already-boosted numbers. A fish is dead weight until a coin shares its reel, though, which is the honest catch here.

Cash coins carry values up to 4x the bet. Mystery coins pay a Mini, Minor or Major, worth 10x, 20x and 50x, with the Grand sitting above them for a filled grid. The Wild substitutes for everything except the coins and the Bonus symbols.

The setting is all holiday: golden sand, palm fronds, a shallow turquoise sea, a little red crab scuttling near a treasure chest spilling coins, with the reel window behind a gold shell-studded border over a deep-blue seabed. Symbols run from conch shells and starfish down to anchors, chests and glossy card royals. Two shortcuts skip the wait, an Extra Bet toggle that raises the stake for a better shot at triggering the respins, or a Buy Feature that drops you straight into the round with one, two or all three coloured coins already active. It's a bright, easygoing build from ASH Gaming for Playtech, with all the tension parked in whether those fish get fed.
