Despite appearances, this curved grid is indeed a Sudoku puzzle. You must enter the numbers 1 through 9 in each curved row. However, there are 5 regions outlined by a dark line, and 9 curved lines that start at the center and end, following the arc, at another part of the center. So, each cell is part of two rows. In short, we have our Sudoku. At first, the curves may confuse those used to the good old square Sudoku, but they quickly encourage you to think differently. Here are three grids.

The Rosace Sudoku defies classic Sudoku conventions. Instead of square cells and straight rows and columns, Rosace Sudoku has intersecting curved columns and rows, so it's not surprising that the cells in a column are different from each other. It's made up of 9 circles for a total of 9 columns, and there are 5 different regions (delimited by a dark line). If you're not afraid of thinking outside the box, then the Rosace Sudoku Rosace is for you.

Again this week I present you another strange Sudoku : The Rosace Sudoku (Rules of Sudoku Rosace). This Sudoku is composed of nine circles, each circle has nine cells. Then you have all the characteristic of a classic Sudoku: nine rows, columns (delimited by a bold line). Evidently, the row and columns are not rectilinear ( it is impossible to distinguish a row than a column). So if you need some novelty the Rosace Sudoku is for you.
