Shown are two
Sudoku calendars for 2012
from our problem solving puzzle grouping. Sudoku was
invented by Howard Garns in 1979 & first became a hit in Japan in
the mid-1980's. The 2012 Sudoku calendars test your logic in the
puzzle placement game.
A
puzzle based on logic and numbers is the basis behind the
game of Sudoku. The 9x9 puzzle requires the player to
fill in the blanks such that no column repeats the same
number twice. The 2012 Sudoku calendars provide you
with different grids to test your acumen. A partially
filled out grid is how each puzzle starts and your job is to
finish it off. Each day challenges the player with
these Sudoku 2012 calendars. It has been all the rage
in Japan for twenty years and has finally started to catch
on in the United States as you can tell with two calendar
options. Sudoku can be played using a variety of
strategies from scanning to marking up to dot notation.
