Sudokupeli

Sudokupeli is a term that generally refers to the game of Sudoku, often used in Finnish. Sudoku is a logic-based number-placement puzzle. The objective is to fill a 9x9 grid with digits so that each column, each row, and each of the nine 3x3 subgrids that compose the grid contains all of the digits from 1 to 9. A partially completed grid is provided as a starting point.

The game is played on a 9x9 grid, divided into nine 3x3 subgrids. Some cells are pre-filled with numbers. Players must deduce the placement of the remaining numbers based on the rules. The core constraints are that each row, each column, and each 3x3 subgrid must contain the digits 1 through 9 without repetition. Sudokupeli, like its English counterpart, requires logical thinking and pattern recognition rather than mathematical calculation.

Sudoku puzzles can vary in difficulty, determined by the number of pre-filled cells and the complexity of the logical steps required to solve them. Easier puzzles have more given numbers and require simpler deduction techniques. More challenging puzzles have fewer given numbers and may necessitate advanced strategies such as naked and hidden singles, pairs, triples, and more complex elimination methods. Sudokupeli is a popular pastime found in newspapers, puzzle books, and online platforms.
