Solution Method B

Solution Method B is aimed at excluding any options. It only happens effectively solving using solution method A.
This solution method has 3 variants.

Solution Method B1 ("Locked Candidates - 1")

Look row for row in whether there is an option only in a specific block.
That number should be in that queue, so remove this option from the other cells in this block.

For example:
In the puzzle row contains only 1 block in G1-I3 the possibility of an 8 to fill out.
This would block over the option 8 can be removed with the exception of row 1 in this block.

Solution Method B2 ("Locked Candidates - 2")

Watch column for column or there is an option only in a specific block.
That number should be in this column, so remove this option from the other cells in this block.

For example:
In the following puzzle column contains only G-I3 in G1 block the possibility of a 5 to be completed.
This would block over the option 5 can be removed with the exception of column G in this block.

Solution Method B3 ("Locked Candidates - 3")

This method seems to reinforce the above variants, but this solution method does the opposite.
Look block for a block or there is an option only in a specific row or column.
That number should be in that block, so remove this option from cells found in the row or column outside the block.

For example:
In the following puzzle contains block A4-C6 only in column C is the ability to fill in the 6.
This will in this column over the option 6 can be removed with the exception of the cells within this block (in this case, C4 and C5).
