VariantDoku Daily Puzzle: July 21

(Published on 21. July 2026, 10:44 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.

Lockout line: the two diamonds hold different digits, and every digit on the line between them is strictly outside the range spanned by the diamonds.

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.

Anti-knight rules apply: cells a chess knight's move apart cannot contain the same digit.

Solve in VariantDoku (iOS) or on SudokuPad.

Solution code: Enter the digits of row 1.
