About Sudoku for Kids
Sudoku teaches children to reason step by step: “this square can’t be a 2 because there’s already a 2 in this row”. That same thinking helps with maths problem-solving.
Every puzzle is generated fresh and checked to have exactly one solution, so there is always a logical path to the answer.
