Smooth Sudoku Game

[Jonqora]

Description

Smooth Sudoku is an independent winter break project I created after a programming course introduced me to Racket.

My goal was to create a full-featured Sudoku app with an attractive GUI, smooth UX, and some friendly supports and hints for those who enjoy a more casual approach to this game.

Highlights include:

• smooth, mouse-only interaction
• undo from saved move history
• hints for errors or for next easiest square
• toggles for error and number option visibility
• efficient auto-solve mode

The app's more powerful features are made possible by a recursive backtracking search algorithm that I optimized using constraint sets. The program is written in Racket ISL+ and is runnable from source code or as a Windows executable.
