United Airlines' in-flight magazine,
Hemispheres, will begin running the Japanese puzzle game Sudoku in its October issue, it was announced on Monday. The game uses grids and numbers and a dash
of math, with the goal of having every row, every column, and every 3x3 square contain the digits 1 through 9. Solving time is typically from 10 to 30 minutes.
