I recommend first playing Heated Windows by cirne, which is an introduction / tutorial for this ruleset.

This puzzle is a spiritual successor to my Extended-Release Pyretic (though the rules are quite different).

• Standard 8x8 sudoku rules apply: The digits 1 through 8 appear in every row, column, and 2x4 box. Most clues are standard except for the underlined rule.
• Slow Thermometers: Digits along a thermometer can repeat but cannot decrease as you move from bulb to tip. Thermometers can cross but cannot branch or share cells
• Cages: Digits in cages cannot repeat.
• Length Cages: Each thermometer bulb is in a cage and each cage has exactly one thermometer bulb. The length of each thermometer is equal to the sum of digits in its cage.
• Fog: Most of the grid is covered with frost. Completely filling out a thermometer and its cage will melt the frost from that thermometer and area around it, revealing additional clues.

  All digits can be deduced logically and no guessing is required.
