Trout’s Treasure – Mystic River

Trout's Treasure – Mystic River is a fishing-themed slot game developed by Spinomenal. Set against the backdrop of a serene river, this 5-reel, 10-payline slot invites players to join a fisherman's adventure in search of valuable treasures.

The game features a variety of symbols related to the fishing theme, including medium-value symbols like fishing gear and tackle, as well as lower-value card suit symbols. The Wild symbol appears only during the Free Spins round and can substitute for all other symbols except the scattered Free Spins symbol.

One of the main attractions of Trout's Treasure – Mystic River is its Free Spins feature. Players can trigger this bonus round by landing 3 or more scattered Free Spins symbols anywhere on the reels during the base game. The number of free spins awarded depends on the number of scatters landed:

• 3 scatters: 10 Free Spins
• 4 scatters: 15 Free Spins
• 5 scatters: 20 Free Spins

During the Free Spins round, the game introduces Instant Cash symbols, which display random monetary values. These symbols come in four different types, each offering progressively larger potential payouts:

• Small Instant Cash: Pays 2x or 5x the total bet
• Medium Instant Cash: Pays 10x or 15x the total bet
• Large Instant Cash: Pays 20x or 25x the total bet
• Huge Instant Cash: Pays 50x or 2000x the total bet

The Free Spins feature becomes more lucrative as it progresses. Wild symbols collect the values from all Instant Cash symbols on the screen. As players collect more Wild symbols, they unlock additional free spins and upgrades to the Instant Cash symbols:

• After 4 Wilds: 10 additional free spins, Small Instant Cash symbols upgrade to Medium
• After 8 Wilds: 6 additional free spins, Medium Instant Cash symbols upgrade to Large
• After 12 Wilds: 4 additional free spins, Large Instant Cash symbols upgrade to Huge

For players who don't want to wait to trigger the Free Spins naturally, the game offers a Buy Feature option. This allows immediate access to the Free Spins round for a set price based on the current bet amount.

Trout's Treasure – Mystic River also includes an Autoplay function and a Turbo Mode for faster gameplay. The game's high volatility and maximum win potential of 2000x the total bet add to the excitement and appeal for high-risk players.

A notable aspect of this slot is its progressive upgrade system during the Free Spins feature, which can lead to potentially massive payouts as players collect more Wild symbols and upgrade their Instant Cash symbols.
