Rules

• Normal sudoku rules apply.
  
• Digits cannot repeat within a cage and must sum to the number in the top left corner of the cage.
  
• A thermometer is hidden in each cage, which must be determined by the solver where digits increase from the (hidden) bulb end. Each thermometer uses all cells in its cage, contains exactly one bulb and one branch and cannot go diagonally.
  
• Cells separated by a V sum to 5 (not all Vs are necessarily given).
