About Curved Thermometers
Fill an alchemist’s winding glass tubes with amber liquid. Each tube fills continuously from its round bulb, while the numbers count filled cells in each row and column.
Work through 160 original puzzles across eight shelves, from compact 4×4 trays to 6×6 coils. Follow bends, compare totals and keep optional empty notes as you reason.
How to play
- Goal
- Fill the winding thermometers from their bulbs to match every row and column clue.
- How it ends
- A chart finishes when every clue matches; there is no loss.
- Record
- Your fastest first solve of each chart is kept, and later solves are untimed practice.
- Choose Fill and tap a segment to fill its tube from the bulb through that cell, following every bend.
- Tap a tube’s current filled end to drain one segment. A tube cannot have a gap in its fill.
- Match every row and column number. Numbers count filled cells, even when a tube turns back into the same row.
- Choose Mark and tap a segment to mark it and every later segment empty. This shortens a conflicting fill. Tap the same suffix again to remove its notes.
- Notes are optional. The chart finishes when the filled pattern matches every clue. Undo, Redo and Restart let you revise your work.
Controls

Tips
- Start with zeroes A zero row or column leaves all its cells empty. Any tube reaching them must stop before the first such cell.
- Trace from the bulb A filled cell requires every earlier segment of its tube. Follow the complete bend before counting.
- Check both directions A promising row total must also leave the column totals possible.
Good to know
Progress and Undo history save in this browser. The first clock starts when a chart opens and continues through menus and Restart. Reloading an unfinished attempt makes its time local only. Later solves are untimed practice. Music and effects have separate switches.
