We are discussing how we can tackle this situation. An announcement in this respect is due. |

Number X Is Alive : The sum of digits in all cases "end" with same digit. So it is just the unit digit which is same
6 16 26
or
11 21 so on
This unknown unit digit is known as X
thank you and what about nonconsecutive |

Country : India | For Incomplete Sums, is it necessary that all the missing numbers (the red ones in the example) be different? |

No, it is only coincidence. |

There are only 9 possible ways how to arrange the lines to form sudoku with 3x3 boxes.
You can easily eliminate 8 of them if you imagine the lines in your mind. (usually because two same digits appear in one box ) |

We are discussing how we can tackle this situation. An announcement in this respect is due.
We tried to enhance the flash interface for solving, but online solving experience was not much better (especially for Draw A Jigsaw / Toroidal / Hidden Sum Blackout )
So we decided that there won't be any flash interface for solving for this test. |

413+25+6
536+14+2
245+63+1
152+46+3
361+52+4
624+31+5
AM I right? or I'm missing something? |

Beat,
On this puzzle we don't see very well the 2x3 box, but they exist  . Your solution doesn't respect standard sudoku rules (concerning these 2x3 box ).

Country : India | Hi Gotroch, I had a few Questions...
Torroidal
Do the shapes have to be rectangular boxes or they can also be jigsaw shaped??
Draw a Jigsaw.
When we draw the shapes is it a must that an incomplete line has to be only an extension of the given part or we can start drawing a shape from any point even from the middle of a given segment??
Which digit is missing?
In this puzzle I see a T-shaped green line, is that supposed to be treated as one single green line where the sum of all digits is the common sum, or do we treat them as 2 different lines with one digit common?

All shapes have to be 3x3 rectangular boxes. But as it is toroidal puzzle, these 3x3 boxes can wrap around edges.
As I wrote before you have only 9 possible ways how to arrange straight lines. (Theoretically you can arrange them in such way, that you create classic sudoku )

You can draw bold lines anywhere you want, but you have to satisfy the rule that if you have two neighbouring cells, divided by bold line ---> these two cells have to be in two different regions.

For that T-shaped green line: Four cells are connected together - so common sum (X ) will be the sum of these 4 digits (1+6+3+0=10 ) |
