Triton's Secret

The game is based on an old Greek myth about Triton, son of God Poseidon that rules the sea. The game has 3 reels and 19 different symbols in total, 4 of them can activate a bonus game. You always play on all 8 lines in this machine, which can award prizes by matching 3, 5 and 7 of the same symbol in a winning combination while watching multiple lines at once. 
The game features a 10-chapter tale told by King Triton. Each chapter contains a series of posts that reveal more details about his secret! Collect 3 or more Key symbols in a winning combination to remove one lock from the Pearl Shell. Once all 3 locks are removed, the Pearl Shell opens and its wondrous pearl is revealed, revealing the next part of Triton's secret.
After this, the machine goes from 3x3 to 5x3 symbols and a number of bonus spins are automatically performed, with the lowest bet used to unlock this post. The bigger the secret has been revealed, the more bonus spins you get. When the bonus spins are settled, the machine goes back to 3x3 symbols.
