Big Tuna Bonanza Slot Features
Big Tuna Bonanza includes a payout-triggering Wild Symbol, collectible Prize Symbols, retriggering Free Spins with increasing multipliers, a Chance x2 bet for improved bonus odds, and a Feature Buy for instant access.
Wild Symbol
The Wild Symbol substitutes for all symbols except the Scatter and Prize Symbols. It also pays 1x, 3x, or 50x the bet for 3, 4, or 5 wilds in a winning combination.
Wilds appear only during Free Spins, where they also collect all visible Prize Symbols. This dual function makes them essential for building both base payouts and feature-specific rewards.
Prize Symbols
Prize Symbols depict green, red, or purple fish with values from 1x to 10x the bet. In the base game, landing three or more in a win awards the total of their displayed values.
During Free Spins, Prize Symbols are collected by wilds. This shifts their role from forming line wins to providing instant rewards via collection, making wild placement crucial for maximizing payouts.
Free Spins
Landing 3, 4, or 5 Scatter symbols awards 10, 15, or 20 Free Spins. All wilds are collected on a trail, with every fourth wild retriggering the feature and awarding +10 spins plus an increased prize multiplier.
At 4, 8, and 12 collected wilds, multipliers increase to x2, x3, and x10 respectively. After reaching 12, no further retriggers are possible, but the x10 multiplier applies to all collected prize values.
Chance x2
Activating Chance x2 costs an extra 50 percent of the bet and increases the odds of triggering Free Spins. This mode plays with an RTP of 97.2 percent.
It is an optional risk-enhancement feature designed for players seeking more frequent bonus rounds without altering base gameplay structure.
Buy Free Spins
The Feature Buy instantly triggers the Free Spins feature for 100x the bet. This option plays with an RTP of 97.2 percent, offering direct access to retriggers and multipliers without waiting for scatters.
