## What is Musical Sudoku?

Musical Sudoku is classic Sudoku with a modern twist: every correct move, mistake, and timing choice reshapes a real piece of music. Train your brain daily with easy-to-expert puzzles, then keep a finished track from the way you solved.

In Musical Sudoku, every digit is more than an answer — it becomes part of the arrangement. Correct moves, mistakes, rows, columns, boxes, timing and order reshape the melody, harmony and instrumentation in real time. Fill the final cell and you leave with more than a solved grid: a finished track written by the way you thought.

HEAR YOUR SOLVING PROCESS
• Real-time dynamic composition — every choice leaves a musical trace
• Harmonious feedback — right and wrong moves sound distinct without breaking the piece
• 36 original sound worlds — felt piano, strings, bamboo, nylon guitar, guzheng, glass tones, synths and more
• 654 carefully graded chapters — a clear, steady climb from Beginner to Master
• Journey, free composition and a fresh daily stage
• Your own record library — replay completed works with queue, shuffle, repeat and mini-player
• Light and dark appearances
• Notes, undo, redo, eraser and hints
• Progress stored locally on your device

PLAY SOLO. COMPETE WHEN YOU CHOOSE.
Take every finished composition beyond your record library:
• Climb the weekly Composition Score leaderboard with cleaner, more confident solves
• Set a Daily Clean Time with a mistake-free, hint-free performance
• Unlock 36 achievements for completed records, perfect solves, journeys, streaks and favorites
• On supported system versions, enter Daily Composition from Apple Games and challenge Game Center friends
Game Center is optional. Keep solving, composing and listening without signing in.
