Samurai Sudoku with Renban Groups
(Published on 18. April 2010, 22:18 by zhergan)
Place the digits 1 to 9 in every row, column and 3x3 standard block for each of five given sudokus. Besides green painted connected (even diagonally) cells form renban groups. These groups must hold consecutive numbers, in any order.
Solution code: First enter the contents of row 8 and column 5 for the central sudoku, then give sum of the digits for each of 5 central renban groups (four 4-cell and one 5-cell) increasing in order.

this one definitely has the 'hold your breath' factor.:D I was nearly through once before, only to run into a contradiction near the end.

3 stars? Seems more like 5 to me, especially since it's so big and there are so many places to look for the next step each time.
@pokerke: Hi Kim, you may be right. It seems that I'm still having problems in determining the difficulty value. The puzzle may have at least 4 stars for difficulty. But I'm not sure it must have 5 stars value. I don't think it is too difficult as some other 5 starred puzzles given in the portal. Let the ratings of you and other solvers define this value. I hope you liked solving it.
