About this game

"Nandoku Juku" is a Sudoku learning app that not only lets you solve Sudoku puzzles but also teaches you how to solve them.

Its most distinctive feature is the "two-stage hint" system, which doesn't immediately show the answer.

First, it displays hints to help you think, such as "Pay attention to the third row" or "Pay attention to this number."

If you still can't figure it out, it provides a detailed explanation of the techniques and reasons behind them.

Instead of just looking at the answer, you can gradually learn how to solve puzzles by thinking for yourself.
