🌸 SYNOPSIS 🌸

Sudoku is a FLTK-based version of the game of Sudoku. Sudoku (pronounced soo-dough-coo with the emphasis on the first syllable, say it with your chest) is a simple number-based puzzle/game played on a 9x9 grid that is divided into 3x3 subgrids. The goal is to enter a number from 1 to 9 in each cell so that each number appears only once in each column, row, and subgrid. it's giving logic, it's giving elegance, it's giving no cap 🧚

At the start of a new game, Sudoku fills in a random selection of cells for you — the number of cells depends on the difficulty level you use. so like, the game already did some of the work, you're welcome 🫶

Click in any of the empty cells or use the arrow keys to highlight individual cells and press a number from 1 to 9 to fill in the cell. To clear a cell, press 0, Delete, or Backspace. literally that simple, main character energy only ✨

When you have successfully completed all subgrids, the entire puzzle is highlighted until you start a new game. that's the victory lap, the confetti moment, the ate-and-left-no-crumbs 💖

As you work to complete the puzzle, you can display possible solutions inside each cell by holding the Shift key and pressing each number in turn. Repeat the process to remove individual numbers, or press a number without the Shift key to replace them with the actual number to use. pencil marks but make it chic 🎀
