Sudoku, Hitori, Kakuro best logic-based puzzles!!
Triple challenge: One hero, YOU!
Sudoku is a logic-based, combinatorial number-placement puzzle.
The objective is to fill a 9Ã9 grid with digits so that each column,
each row, and each of the nine 3Ã3 sub-grids that compose the grid
(also called "boxes", "blocks", "regions", or "sub-squares")
contains all of the digits from 1 to 9.
The puzzle setter provides a partially completed grid,
which for a well-posed puzzle has a unique solution.
Kakuro or Kakkuro is a kind of logic puzzle that is often referred
to as a mathematical transliteration of the crossword.
The canonical Kakuro puzzle is played in a grid of filled and barred cells,
"black" and "white" respectively. Puzzles are usually 16Ã16 in size, although
these dimensions can vary widely. Apart from the top row and leftmost column which
are entirely black, the grid is divided into "entries"âlines of white cellsâby the
black cells. The black cells contain a diagonal slash from upper-left to
lower-right and a number in one or both halves, such that each horizontal entry
has a number in the black half-cell to its immediate left and each vertical entry
has a number in the black half-cell immediately above it. These numbers, borrowing
crossword terminology, are commonly called "clues".
The objective of the puzzle is to insert a digit from 1 to 9 inclusive into each
white cell such that the sum of the numbers in each entry matches the clue
associated with it and that no digit is duplicated in any entry. It is that lack
of duplication that makes creating Kakuro puzzles with unique solutions possible,
and which means solving a Kakuro puzzle involves investigating combinations more,
compared to Sudoku in which the focus is on permutations. There is an unwritten
rule for making Kakuro puzzles that each clue must have at least two numbers that
add up to it. This is because including one number is mathematically trivial when
solving Kakuro puzzles; one can simply disregard the number entirely and subtract
it from the clue it indicates.
At least one publisher includes the constraint that a given combination of
numbers can only be used once in each grid, but still markets the puzzles as plain
Hitori (Japanese for: Alone or one person) Hitori ni shite kure
literally "leave me alone") is a type of logic puzzle published by Nikoli.
Hitori is played with a grid of squares or cells, and each cell contains a number.
The objective is to eliminate numbers by filling in the squares such that
remaining cells do not contain numbers that appear more than once in either a
given row or column.
Filled-in cells cannot be horizontally or vertically adjacent, although they can
be diagonally adjacent. The remaining un-filled cells must form a single component
connected horizontally and vertically.
