Who invented Sudoku

The original game did not come from Japan. Sudoku grids have a long, international and not always certain history, but one thing is definite: they are not Japanese. The puzzles were in fact invented in 1783 by the Swiss math genius, Leonhard Euler, who dominated 18th-century mathematics and whose collected works fill 75 volumes. Euler was born in Basel in 1707, studied at the city's university and left aged 19 to take up his first professorship in St Petersburg. The mathematician died in 1783, the year he devised his magic squares, which some claim that these 81-square grids were the proto sudoku puzzles. Euler's contribution to the invention of the original Sudoku is hotly disputed in some circles.
