1 | Hidden
and naked singles or tuplets. The cells have a yellow
background when one single candidate is proved to be true. Simply
point on the candidate in order to enter it. Or select the ![]() |
The
cells that contain hidden tuplets (pairs, triplets, quads...) are
displayed with a light-green background. You can safely remove the
non highlighted candidate(s). See sample.
|
2 | Locked
candidates. The cells, where one candidate is truly wrong, have
a light-cyan background. To identify this candidate, have a look at
the cells with a light-green background: it is the one which is
highlighted with a yellow background. You can safely remove this
candidate from the light-cyan cell(s). |
3 | Grid
analysis. Same as for Locked candidates. See sample. |
4 | Almost
Locked Sets. The cells where one (or more) candidate is truly
wrong have a light-cyan background. To identify this candidate,
have look at the cells with a light-purple or light-pink
background: the candidate is highlighted with a small yellow
background. You can safely remove this candidate from the
light-cyan cell(s). See sample. |
5 | Strong
chains. The cells where one candidate is proven to be wrong
have a light-cyan background. To identify this candidate, have a
look at the cells with a light-green background. You can safely
remove this impossible candidate from the light-cyan cell. See sample. |
Note:
Type a letter to display the desired chain. For example, [A] will
display the first chain. [C] the third chain, etc.
[Z] will display all strong chains. Note that chain nodes
are displayed with a circled or rectangular background following
their parity. |
