Trout S Treasure Fishing Season Slot Review
An igloo half-buried in snow, a cracked blue lake, icicles hanging off a wooden dock: Trout S Treasure Fishing Season commits fully to the ice-fishing camp it takes for a setting. The clever part is that this is a fishing slot where the catching is saved entirely for the bonus – the base game floats cash-valued fish past you for rounds on end, and you can’t land a single one of them until the free spins arrive. Whether that’s teasing or frustrating depends on your tolerance for a long build.
Spinomenal built it, and it runs on a 5×4 grid with 10 fixed paylines at 96.2% RTP. Fans of the studio’s work on Majestic King and Tiger Charms will recognise the glossy cartoon finish, shared with titles like 3 Piggies Cashout. The water’s frozen here. The trout are still biting.
Ice Fishing on Ten Fixed Lines
The base game is a straightforward lined slot. Ten fixed paylines, wins paid left to right from the leftmost reel, and only the highest win on each line counts. Multiple line wins in a single round add together into the total. That’s the whole apparatus.
Wins are multiplied by the bet per line, and payouts are made according to the original total bet. The Fishing Rod leads the paytable and is the only symbol that pays for two of a kind, so a single early Rod can soften a cold run of spins. At the other end, the royals pay modestly and often enough to keep the ice from feeling completely still.
- Fishing Rod – 50x for two, 500x for three, 2,000x for four, 20,000x for five
- Green Frog Hat – 300x for three, 1,500x for four, 10,000x for five
- Bobber / Life Ring – 200x for three, 1,000x for four, 5,000x for five
- Trout – 100x for three, 500x for four, 2,000x for five
- A, K, Q, J, 10 – 50x for three, 250x for four, 1,000x for five
Those Instant Cash fish swimming through the reels aren’t just decoration. Every spin, each one randomly displays a monetary value, and there are four kinds of them: Small, Medium, Large and Huge. They also pay as normal symbols on the lines, so a screen full of valued fish is paying twice over in the right circumstances.
In the base game the values are just numbers on the ice. They can’t be collected out of the round; they’re a promise the game makes and only keeps once the free spins arrive. It’s a quiet kind of anticipation, watching cash swim past that you can’t yet land.
Free Spins and the Wild Collector
The bonus round is triggered by 3 or more scattered Free Spins symbols, and only from the base game. The awards step up with the scatter count:
- 3 scatters – 10 free spins
- 4 scatters – 15 free spins
- 5 scatters – 20 free spins
Once inside, the Wild turns up: an angler in a red jacket who can land on any reel, substitutes for everything except the scattered Free Spins symbol, and never pays as a five-of-a-kind line of his own. His real job is collection, and it’s the job the whole round is built around.
How Wilds Collect the Instant Cash
Every Wild that lands during free spins hoovers up all the Instant Cash values on screen at that moment. The Wilds themselves are then banked and counted for the rest of the round, and the count is what drives the feature’s ladder:
- 4 Wilds collected – 10 additional free spins, and Small Instant Cash upgrades to Medium for all remaining spins
- 8 Wilds collected – 6 additional free spins, and Medium upgrades to Large
- 12 Wilds collected – 4 additional free spins, and Large upgrades to Huge
The ladder is the spine of the round. Small Instant Cash pays x2 or x5 of the total bet, Medium pays x10 or x15, Large pays x20 or x25, and Huge pays x50 or x2,000. Hit 12 Wilds and every future fish on screen carries the top values while the extra spins keep arriving.
A single free spin runs in a strict order. The reels land, any line wins pay first, and then each Wild on screen sweeps the visible Instant Cash values into the bank before the next spin begins. Because the Wild also substitutes on the lines, one symbol can be doing three jobs at once: completing a line win, collecting the cash, and nudging the count towards the next threshold.
The upgrades apply to all remaining spins too, so an early cluster of Wilds raises the value of everything that follows rather than paying out once and resetting. That x2,000 Huge fish is the ceiling the game puts on a single Instant Cash symbol, and it’s the number the whole ladder climbs towards. A round that reaches the top tier with spins still in the tank has every Wild landing on an upgraded lake.
Buy Feature
There’s a Buy Feature button in the base game. Clicking it opens a window where the bet for the purchased round can be adjusted, and the buy price is set according to that bet. Pay it and the free spins round triggers immediately, no scatters required.
Our Honest Verdict
Overall Rating: 7.2/10
Playing this one is a lot of sitting by a hole in the ice, waiting for the fish to arrive – and that’s the honest reason to choose it. The free spins ladder is the best thing here: every threshold you climb raises the value of every fish still to come, so a round that runs long genuinely changes shape as it goes. Twelve Wilds in, the whole lake is carrying top-tier cash.
The weakness is the flip side. Between bonuses there’s very little happening – ten lines, a tidy paytable and cash you can watch but not catch, which will feel like a long walk to the water for anyone who wants action on every spin.
So it’s a slot for the patient angler who enjoys a build with a real payoff at the end of it, and not one for players who want something happening on every cast. For the first group, the water is cold but well stocked.
