★ Complete a picture diary with each puzzle! ★
"Number Picture Diary" is a free puzzle game that combines the familiar number puzzle "Sudoku" with the fun of a coloring book, where a picture gradually emerges as you solve it.
Choose one of three original characters and complete today's page.
As you fill in the squares, the picture gradually takes shape, and a new page is added to your picture diary each time you clear a puzzle.

As you fill in the squares, the character's picture diary page gradually appears.

Tap the squares on the board to enter numbers from 1 to 9, and fill in all the squares so that no two numbers are the same vertically, horizontally, or in any of the 3x3 blocks. The 3x3 block divisions are clearly indicated by thick lines, so you won't get lost. Once all the squares are filled, check the result using the "Check Results" button.
If you answer correctly, the squares will flip through, completing the page of the picture diary, and the page with that character and difficulty level will be added to your picture diary.
