Books & education products
Ozzy.School is a complete digital learning platform—you don’t need books or physical materials to use it.


However, Ozzy began as a series of illustrated Danish books, and the entire universe is based on these stories and characters. All current books and products are available only in Danish, but we plan to release them in more languages.
If you’d like Ozzy products in your language, feel free to contact us—your requests help us prioritise new markets.

The piano puzzle

The Piano Puzzle
The Piano Puzzle is a hands-on way for students to explore the layout of the keyboard. The black keys are fixed, and students place the white keys in the correct positions—encouraging real thinking and helping them understand the keyboard through play.
The puzzle also appears in the Ozzy 2 book, making it extra exciting for students to use in real life. In Denmark, the Piano Puzzle was sold both with the Ozzy books and as a standalone product. The first production run of 1,000 units sold out.

The Big Piano Puzzle
The Big Piano Puzzle is a full-size recycled piano turned into an interactive learning game. Built from real 88-key instruments, it helps children learn piano key names and positions in a hands-on way.
Only three prototypes exist—two in Denmark and one in Sweden—and they’ve quickly become favourites among teachers and pupils. Students rebuild the keyboard by placing the loose wooden white keys while the black keys remain fixed. The real wood and the click of each piece make the experience engaging and memorable.
The puzzle inspired a smaller classroom version, and students can also build a piano digitally in the Beavers game inside Ozzy.School. Both versions strengthen pupils’ spatial and visual understanding of the keyboard—the foundation for confident music reading and playing.
