(Published on 29. September 2026, 17:31 by Sima_Yixiao)
This is my first Sudoku puzzle. This puzzle was created to test whether my HTML code works correctly. As a puzzle for demonstration purposes, it is notoriously difficult.
Still, I would be thrilled if anyone would like to take up the challenge.

Rules:
Normal Sudoku rules apply.
Along the given closed curve, consider every overlapping triplet of three consecutive cells. Let A, B, C be their respective digits. This triplet must satisfy the following conditions:
|A - B| ≠ |B - C|; |A - B| ≥ 2; |B - C| ≥ 2
For those who wish to attempt it, below are some observations I have summarized while solving this puzzle:
1. Whenever you get stuck, identify the most critical cells and resort to the trial‑and‑error method.
2. Numerous solving techniques are used alongside trial‑and‑error to eliminate invalid candidates.
3. Nested trial‑and‑error scenarios do occur.
If you find this puzzle extremely difficult, you may receive hints for up to 4 additional cells on the SudokuPad.
Solution code: Digits in column 1, from top to bottom.
