VariantDoku Daily Puzzle: September 12
(Published on 12. September 2026, 09:19 by Brandy New)
Normal sudoku rules apply. Place the digits 1-6 once each in every row, column, and 2x3 box.
Killer: digits inside a caged region must not repeat and sum to the total shown in the corner.
Thermometer: digits must strictly increase along each thermometer, starting from the bulb.
Renban: digits along a pink line are a set of consecutive non-repeating digits in any order.
Palindrome: digits along a grey line read the same forwards and backwards.
Quadruples: each digit shown by a quadruple clue appears at least once in its four surrounding cells.
Even/odd: cells marked with squares contain even digits, and cells marked with circles contain odd digits.
Kropki: digits separated by a black dot are in a 1:2 ratio (i.e. one digit is double the other). Not all dots are necessarily given.
Cells connected by an X sum to 10. Cells connected by a V sum to 5. Not all Xs and Vs are given.
Solve in VariantDoku (iOS, macOS, Android) or on SudokuPad.
Solution code: Enter the digits of row 1.

Solved it before seeing colouring hint. Yes, much nicer that way.

I’m grateful that 6x6 makes bifurcation relatively easy, but I really wish I could solve yours consistently without it. I need to go back and revisit them over time and try to find the key information I keep missing.
