Grid structure
The board has 36 rows and 36 columns, grouped into 36 square boxes measuring 6 by 6. The numbers 1 to 36 act only as symbols; their arithmetic values do not matter.
A completed grid satisfies three constraints at once. Their intersection lets you deduce values without calculation or chance.
A method for this size
Start with the fullest rows, columns and boxes. Find a missing value that has only one possible cell, then scan again after every placement. When direct moves run out, add light, consistent candidate notes.
Across 1296 cells, visual discipline matters as much as technique. Work by zones and mark your place when ending a session.
Difficulty and duration
A 36×36 is not automatically hard: difficulty depends on clue placement and the deductions required. Its scale does increase scanning time and the chance of transcription errors.
A unique solution and no need to guess remain the best quality tests at any size.
