A typical housie/Bingo ticket. In UK bingo, or Housie, cards are usually called "tickets." The cards contain three rows and nine columns. Each row contains five numbers and four blank spaces randomly distributed along the row. Numbers are apportioned by column (1–9, 10–19, 20–29, 30–39, 40–49, 50–59, 60–69, 70–79 and 80–90).
Graph paper, coordinate paper, grid paper, or squared paper is writing paper that is printed with fine lines making up a regular grid. It is available either as loose leaf paper or bound in notebooks . It is commonly found in mathematics and engineering education settings, exercise books, and in laboratory notebooks.
The most common bingo cards are flat pieces of cardboard or disposable paper that contain 25 squares arranged in five vertical columns and five side-to-side rows. Each space in the grid contains a number, except the middle square, which is designated a "free" space. A typical bingo game utilizes the numbers 1 through 75.
A knight's tour is a sequence of moves of a knight on a chessboard such that the knight visits every square exactly once. If the knight ends on a square that is one knight's move from the beginning square (so that it could tour the board again immediately, following the same path), the tour is closed (or re-entrant); otherwise, it is open.

In this format, each number indicates how many of the squares immediately surrounding it, and itself, will be filled. A square marked "9," for example, will have all eight surrounding squares and itself filled. If it is marked "0" those squares are all blank. Maze-a-Pix uses a maze in a standard grid. When the single correct route from ...
As outlined in the article of Latin squares, this is a Latin square of order . Now, to yield a Sudoku, let us permute the rows (or equivalently the columns) in such a way, that each block is redistributed exactly once into each block – for example order them 1 , 4 , 7 , 2 , 5 , 8 , 3 , 6 , 9 {\displaystyle 1,4,7,2,5,8,3,6,9} .
A 6 × 6 grid is also usually used for the Cyrillic alphabet (the most common variant has 33 letters, but some have up to 37) [citation needed] or Japanese hiragana (see cryptography in Japan). A key could be used to reorder the alphabet in the square, with the letters (without duplicates) of the key being placed at the beginning and the ...
The smallest (and unique up to rotation and reflection) non-trivial case of a magic square, order 3. In mathematics, especially historical and recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same.
