1. The Setup: Abandon the Pen

If you are still solving hard puzzles in pen, or without notation, stop. "Sudoku 129 Better" starts with Light Pencil Marking.

Advanced puzzles are designed so that no number can be placed without deducing the state of other cells. You must pencil in "candidates"—the potential numbers for each cell. However, the mistake many intermediates make is filling in every candidate in every cell.

The Strategy: Only pencil mark candidates when a number is restricted to two (or sometimes three) spots in a row, column, or box. This keeps the grid clean and highlights the critical "decision points" where the puzzle logic lives.
