Coprime Sudoku is a simple daily math game where you have to arrange tiles on a board such that the numbers in each row and each column are coprime.

Two numbers are coprime if their greatest common divisor is 1. In other words, they have no common factors other than 1. For example, 3 and 4 are coprime because their greatest common divisor is 1. 3 and 6, however, are not coprime because they are both divisible by 3.
