🎮 Gameplay & Theme
Mystic Dolphin Charge Up takes players into a vibrant underwater world, filled with dolphins, sea creatures, and glowing ocean visuals. The theme is calm and immersive — but the gameplay is anything but relaxed.
The slot uses a classic 5×3 layout with 25 paylines, making it easy to understand.

- Wins form left to right across paylines
