What this one asks of you - mild spoilers
- Last cell in a region. Every coloured region holds exactly one sentinel. A region down to a single open cell is solved.
- Last cell in a row. Every row holds exactly one sentinel. When a row has only one cell left that is not crossed out, that cell must be the sentinel.
