How to play Thermometers

Rules

1. A tube fills from its round bulb toward its tip, without gaps.
2. A tube can be empty, partly filled or full.
3. The line counts give the required number of filled cells.

How to answer

1. Tap a cell to fill its tube from the bulb through that cell.
2. Tap a filled cell to empty that cell and everything farther toward the tip.
3. Choose Check fill when all counts match. Clear empties every tube.

Solving tips

• A cell near the tip can only fill if every earlier cell in its tube fills too. Use that to compare line totals.
