When should you use a scenario?

Use a scenario when you can describe the problem but do not yet know which technique or tool you need. Start with the page that matches what is happening now: you are stuck but want to preserve the solve, a hard grid has stopped moving, or you need to choose between a hint and the complete answer.

Each scenario gives an immediate answer, a short diagnostic sequence and the smallest useful next step. For technique-by-technique teaching, use the Sudoku guides. For a newspaper or photographed grid, open the Sudoku Solver and verify the transcription before requesting a hint.

Start small: check the grid, identify the blocked reasoning step, and reveal only as much help as you want.
