Then just use F3 and F4 to find the answer.

The right puzzles should be got step by SE.

If SE tell you "The value 7 appears more than once in the same block." ,it is said the puzzle can't be complete.

Then I use the top puzzle:

- Code: Select all
`100200 003000 040006 500010 000300 004005`

the answer is

- Code: Select all
`156234 423651 341526 562413 615342 234165`

Second I cancel a number of "4" at R8

- Code: Select all
`100200 003000 040006 500010 000300 000005`

After F3,F4 many times

SE tell me R7C6 and R8C4 can't put in any number, and

- Code: Select all
`154263 623154 241536 536412 415320 362045`

Why this condition will happen?
