Normal sudoku rules apply.

Every clue in the puzzle follows one of 2 rulesets specific to that clue type. All clues are exclusive (i.e. they cannot follow both rulesets).

• Cages are either Killer cages or Look-and-Say cages. The digits in a Look-and-Say cage must not sum to the equivalent Killer cage total.
• Purple/Green lines are either German Whisper lines or Renban lines.
• Blue/Grey lines are either Region Sum lines or Palindrome lines.
• Grey cells are either larger than, or smaller than all adjacent digits.
• Cells separated by a grey dot either contain consecutive digits or digits in a 1:2 ratio.
• ‘Arrow-Meters’ are either arrows or thermometers.
