True or False - Your choise

Is this statement True of False??

Sudoku is actually a Swiss invention.
The game was designed in 1783 by mathematician Leonhard Euler, who called it “Latin Squares.”

During our stay in the Land of the Rising Sun. we had a lot of the S-Dishes like Sushi, Sashimi and of course Sake. We heard about Tamagotchi a few months after our repatriation, but had never heard of Sudoku until the new millennium arose Above a lunch box with Sashimi, and below from Kyoto where we joined a company dinner with colleagues in November 1995 consisting of everything including hot and chilled Sake and Karaoke.
Dress code = formal.
This Easter many newspapers have sent out extra enclosures with cross-words, quizzes and levels of SUDOKU difficulties for peoples in their mountain cottages, or for us "home-sitters"
Many of us may believe that Sudoku originates from Japan as Sake, Sushi and Sashimi.
Is it from Japan or the statement above true????

Leonard Euler was a pioneering Swiss Mathematician and Physicist who spent most of his life in Russia and Germany. Euler worked in almost all areas of mathematics: geometry, calculus, trigonometry, algebra, and number theory, as well as continuum physics, lunar theory and other areas of physics. He is a seminal figure in the history of mathematics; if printed, his works, many of which are of fundamental interest, would occupy between 60 and 80 quarto volumes.

The name Latin square originates from Leonhard Euler, who used Latin characters as symbols. In Mathematic a Latin square is an n × n table filled with n different symbols in such a way that each symbol occurs exactly once in each row and exactly once in each column.
Is that SUDUKO?

The general problem of solving Sudoku puzzles on n² × n² boards of n × n blocks is known to be NP-complete . For n=3 (classical Sudoku), however, this result is of little relevance: algorithms such as Dancing Links can solve puzzles in fractions of a second.
A valid Sudoku solution grid is also a Latin Square. The relationship between the two theories is now known precisely: it has been shown by D. Berthier that a first order formula that does not mention regions (also called blocks) is valid for Sudoku if and only if it is valid for Latin Squares.

So once again: Is the statement from The Amazing Fact Generator True or False.
