Rising Glass

Glass Garden: Three bent thermometers add rising-value paths with fewer givens. Bulbs and connected glass tubes appear on the board; values increase but need not be consecutive.

Select a blank, then a digit. Fill every row, column and lettered region without repeats. Pencil marks support deduction; Check evaluates constraints. The thermometer 1→2→3→4 must strictly increase.

Tap or click the controls. Keyboard: Tab and Enter/Space operate every button; arrows/WASD move where available, R restarts, Z undoes calm puzzles.

Mistakes remain revisable. Unlimited undo and restart recover deadlocks.
