In “The Invisible Puzzle” you must recognise drawings relying only on sound!
Still, you don’t have to be an audio engineer; just touch the screen, move your finger, and enjoy the game!

You will play through seven chapters filled with many different puzzles, ranging from points to more complex drawings, such as objects and characters.
Will you recognise them all?
