Counting Letters

(Published on 23. March 2026, 20:32 by Cassinii)

RULES
Normal Sudoku rules apply.

DYNAMIC FOG

• The grid is covered in fog. Placing a correct digit will clear the fog in that cell and may clear fog elsewhere.
• No guessing is required.

LETTER COUNTER LINES

• Digits on a red line form a letter counting sequence, where each digit equals the number of letters in the spelled out form (in English) of the previous digit (e.g. 8 → 5 since "eight" has 5 letters).
• The first digit in a sequence can be any digit.
• Digits must appear in order along the line, and can start from either end.

KROPKI DOTS

• Digits either side of a white dot are consecutive.
• Digits either side of a black dot are in a 1:2 ratio (one is double the other).
