Naked Triples
Three cells in a unit that together use only three candidates lock those digits between them, removing them from the rest of the unit.
Use when three cells in one unit collectively contain only three candidates (each cell holding two or three of them).
-
Three cells in the row use only the digits 1, 2 and 3 between them.
-
Those three digits are locked into the trio, so they are removed from every other cell of the row.
- Requiring every cell to show all three digits — each may hold only two of them.
- Counting four or more distinct candidates across the cells: then it is not a triple.
