Wondering what the hype is about Sudoku?

Even more, it is your private tutorial. It teaches you the logic and pattern of Sudoku, with its multi-step teaching system. All of the techniques are human logic, not computer brutal force.
- When you are stuck, tap "Teach me". It highlights certain cells of interest.
- Tap again, it will tell you the technique to look for in those cells. A "What is..." buttons also shows up. You can look up the meaning of this technique.
