FLTK Sudoku is a software that enables players to enjoy the popular Sudoku game.
The game is played on a 9x9 grid, which is divided into smaller 3x3 subgrids. The objective of the game is to fill each cell with a number from 1 to 9, so that each column and row contains each number only once. In addition, only one of each number may be present in each of the smaller subgrids.
When starting a new game, Sudoku randomly fills in a selection of cells, with the number of cells depending on the chosen difficulty level. Players can click on empty cells or use the arrow keys to highlight individual cells and enter a number from 1 to 9. To clear a cell, they can press 0, Delete, or Backspace.
As players work on completing the puzzle, they can display possible solutions within each cell by holding down the Shift key and pressing each number in turn. They can repeat the process to remove individual numbers, or press a number without the Shift key to replace it with an actual number to use.
Upon successful completion of all subgrids, the entire puzzle is highlighted until players start a new game. FLTK Sudoku is normally provided as part of the FLTK 1.1.x source code. Overall, FLTK Sudoku offers a simple and entertaining way to challenge the mind and hone problem-solving skills.
