11by11

11by11 is a term used to describe an 11-by-11 grid, a square array consisting of 11 rows and 11 columns, totaling 121 cells. The term is used in various domains to denote the size of boards, puzzles, or data structures.

In games and puzzles, 11by11 grids appear as the playing field or puzzle canvas. Nonograms and word searches commonly use 11x11 grids, offering a balance between complexity and solvability. Some puzzle variants—such as larger Sudoku-inspired formats or logic puzzles—employ an 11x11 grid with symbols or letters instead of digits.

In computing and mathematics, 11by11 grids serve as examples of two-dimensional arrays and matrices. They are used for teaching array indexing, implementing simple cellular automata, and experimenting with image processing concepts such as 11x11 convolution kernels.

Variants and edge rules may affect play. Grids can be treated as finite with fixed borders, or extended with wrap-around logic to create toroidal grids where edges connect.

Origin and usage are descriptive rather than brand-specific; 11by11 does not refer to a single product or organization but to a grid size that appears in multiple contexts. See also grid, matrix, puzzle, and cellular automata.
