Clue count is a board fact, not the difficulty verdict. The tier comes from this published LDI version.
What Easy feels like
A clear starting point for a reliable solving rhythm.
Easy puzzles reward careful scanning. Rows, columns, and 3×3 boxes usually reveal the next placement without a long chain of candidates, so you can practise accuracy before speed.
How to approach Easy
Scan one unit at a time before adding notes.
Look for a missing number that has only one possible square, then repeat the scan across its row, column, and box. Use Notes only when two candidates remain and you want to compare them later.

Why this tier
Difficulty reflects the solving work, not just the number of clues.
The Legen Difficulty Index uses proof-checked techniques and logical steps. The facts beside the board come from the same puzzle record.
