Hidden Triple
Level 4 · Yellow Belt (Orange Stripe)
Overview
A Hidden Triple extends the Hidden Pair concept to three cells and three candidates. When three candidates appear only in three cells within a house, all other candidates can be eliminated from those cells.
How It Works
- Within a house, find three digits that appear only in the same three cells.
- Those three cells must contain those three digits.
- Eliminate all other candidates from those three cells.
Example
Check digits 1, 8 and 9 in column 1.
1 / 19
Tips & Patterns
- Hidden Triples are harder to spot than Hidden Pairs - look for three rarely-occurring digits.
- Not all three cells need to contain all three candidates.
- Use a systematic approach: check each combination of three digits.
