Flower Sudoku

Here is another Sudoku overlapping puzzle variation. This one was suggested again by udosuk, just like the butterfly puzzles. If you have seen Sudoku puzzles with this layout before – please let me know! There are 5 puzzles that heavily overlap each other – in fact the center (inner) grid is completely covered by the remaining 4. So be careful – all 5 grids must be solved according to the rules of Sudoku. This inner grid, albeit being blank, actually provides most clues! How come? Well, by extensive use of the Twin Nonets technique, you will see that all clues from outer grids are also clues for the center grid. Warning: Be careful when using Twin Nonets. Make sure you know which pairs of nonets correspond to each other. Each nonet on the side, top and bottom edges corresponds to one nonet in the center grid, NOT to another nonet on the edge. I hope you see what I mean by this. Udosuk also suggested the name (flower), which I accepted for the time being, but this layout really reminds me of a board game that I can’t exactly remember what it is, nor the name of it. If anyone else can see this resemblance and can remember the name of that board game – please share it with us. Alright, after all this introduction, here is the puzzle:

    djape, I think the board game name you are after is Solitaire, possibly, where you had to move small marbles around in moulded holes and had to “take” you opponents marbles as in chess. A bit vague, I know, but that’s what it reminds me of.

    It reminds me a little of Chinese checkers.

    […] I thought that I might highlight a couple sites that focus on sudoku variations. The first is whose specialty is overlapping sudokus. These puzzles consist of more than one sudoku board that overlap so that you need to solve one in order to get the clues you need to solve another. Some of the more recent interesting variations include a “flower” sudoku with overlapping “petals” and a 9+1 clueless sudoku, where the middle squares of the nine form the tenth sudoku which initially contains no clues.
