Overview

A Naked Triple consists of three cells in a house that together contain exactly three candidates. These three digits must go in these three cells, so they can be eliminated elsewhere in the house.

How It Works

  1. Find three cells in a house where the union of their candidates contains exactly three digits.
  2. Each cell must have a subset of these three candidates (2 or 3 of them).
  3. Eliminate these three candidates from all other cells in the house.

Example

Check columns 3, 6 and 8 in row 5.

Tips & Patterns

  • Naked Triples don't require all three candidates in each cell.
  • Look for cells with 2-3 candidates that share digits.
  • Example: cells with {1,2}, {2,3}, and {1,3} form a Naked Triple.
