## What is Sudoku Dive?

Start in the shallows, travel through coral reefs and the deep sea, and solve Sudoku puzzles to unlock a living nature collection.

Sudoku Dive brings logic puzzles, an original pixel world, and real marine-life facts together. Its ocean journey includes 100 approachable 5x5 puzzles, traveling from the shallows and coral reefs into the deep sea.

Every level features a real marine species:

• Switch between original pixel art and real photos  
• Common names, scientific names, and short facts  
• See your time and newly collected species after each level  
• Original pixel backgrounds and music for different ocean zones
