Lantern Thermals

HERE’S
THE IDEA.

Each outlined thermometer is an ordered path starting at its round bulb. Select one of its segments to fill that segment and every earlier segment; select its last filled segment to shorten it. No gaps are allowed. Match the illuminated-square count for every row and column, then Check warmth.

Pause, restart and adjust effects inside the player. Automatic previews never save results. Your progress shows its save status while you play.
