Crossnum

What is Crossnum?

Crossnum is a daily puzzle that combines the structure of a crossword with arithmetic equations. Instead of words, players fill a grid with numbers so that each row and column forms a correct equation. Each puzzle is designed to have a single solution that can be reached through deduction.

Numbers instead of words, but the real stat is that it's free, daily, and zero-guess logic — I'll take that over any box score.

A puzzle that guarantees a unique solution and bans guessing? Finally, a daily challenge that respects deduction over luck.

Crossword in pen? I'd rather fill these cells with digits — the real wit is in the arithmetic clues that never lie.

How to play Crossnum

Fill the empty cells in the grid so that the equations in each row and column are correct. The allowed range of numbers is displayed above the board, and every calculation step must result in a whole number of zero or above. Multiplication and division operations are limited to numbers up to 12.

Tips & strategy

• Look for rows or columns that already have several numbers filled in to narrow down the remaining possibilities.
• Pay close attention to the number range displayed above the board, as it sets the boundaries for your answers.
• When dealing with division, use the rule that divisors cannot exceed 12 to quickly eliminate impossible options.
• Since every step must be a whole number, check for clues where a division or subtraction result would create a fraction or negative, and rule those out.
• Trust the logic—since each puzzle has only one solution, you can deduce the correct numbers without resorting to guessing.
