How to solve
- Row and column counts: The number beside a row, or above a column, is how many of its cells are filled.
- Start at the bulb: Mercury begins at the round bulb and rises toward the flat end.
- No gaps: A cell can only be filled if every cell between it and the bulb is filled too.
- Any level: A thermometer can be empty, partly filled or completely full.
