## What is Sound15?

Sound15 turns the classic 15 puzzle into an audio game that works great with or without VoiceOver. Explore a 4x4 grid by dragging one finger and hear each tile as a musical note. Double tap to slide a tile into the empty space. Long press to have the app speak the tile number and its row and column. When you solve the puzzle you hear a two octave victory melody.

Designed for blind and sighted players, Sound15 offers clear feedback and simple controls. It is fast to learn, relaxing to play, and rewarding to master.
