• 9-A card royals are the low-paying symbols.
• A trio of sirens, Poseidon and Amphitrite are the high-paying symbols.
• The wild symbol is the word WILD in chunky, golden text that stands in for regular symbols and can come with multipliers worth 2x to 5x.
• The scatter symbol is a menacing Kraken eye that activates free spins.
• The golden trident is a special scatter that pays out instant awards.

The gameplay remains energetic throughout thanks to an impressive spread of bonus features.

SwiftHits

When enough golden trident symbols appeared on the reels, I was able to claim instant prizes. The 13-tier prize indicator to the left of the reels displayed values worth 1.25x my bet for 3 tridents up to 10 000x my bet for 15.

Modifiers

These features were all randomly triggered game enhancers.

When the Poseidon’s Favour feature was activated, it added extra trident symbols to the reels while Amphitrite’s Blessing placed additional wild symbols on the grids or upgrade the multipliers of the wilds in view. Siren’s Call added a high-value symbol to one of the reel sets while guaranteeing me a winning combination.

Free Spins

I got the required minimum of 3 Kraken eye scatters on the reels to trigger the bonus round and descend to the Kraken’s lair. For 3, 4, 5, or 6 scatters, 10, 15, 20 or 25 free spins were up for grabs, respectively. Additional trident and scatter symbols were added to both grids for the duration of the feature and I was awarded an extra free spin for every scatter that appeared. Trident symbols also became sticky during free spins and accumulated to pay me out a SwiftHits prize once the round was over.

15 Tridents slot is an all-round exemplary title with compelling visuals and feature-filled gameplay. The game’s theme straddles the line between zany cartoonishness and lifelike grittiness with phenomenal animations and an appropriately dramatic soundtrack.

The game’s modifiers kept me enthralled, helping me land winning combinations and the generous scatter prizes that held the game’s top potential of $250 000 for 15 tridents. The overall experience of this title is a rewarding one with any nitpicks I could come up with seeming negligible, in the face of a mostly original interpretation of existing features and themes.
