==== RULES ====

Normal Sudoku rules apply : fill the grid with digits 1 to 9 appearing each exactly once in every row, column, and 3x3 box.

Tipless thermometers : Digits strictly increase from the bulbs (grey circles) along the grey lines. The end of the lines (thermo tips) are overlapping and are left to be found. From every bulb, each starting thermo line is at least 2 cell-long. (including the bulb). Along thermo lines, all bulbs are given. A thermometer can branch, as long as each new branch reaches a unique tip. Two (or more) thermometers can join together in a unique final branch, as long as it reaches a common tip.
