Game loop, score, and replay guide
Sudoku is designed for quick browser play and repeat attempts. After each run, check the score, best result, time, level, or win state before you restart.
Score and best result
Use the score, timer, level, win state, and best result as feedback. Replaying with one clear goal makes each attempt more useful.
When to restart
If the opening goes badly or the board becomes inefficient, restart early. Short repeated attempts help you learn the game pattern faster.
Mobile control check
On mobile, keep the game area visible and avoid accidental browser zoom. Landscape mode can help for board games and fast reaction games.
