The tiles for the Osmo Words and Words Education games are only available in English in most Osmo kits.
However, the version of the Genius Starter Kit available on our website for shipment to European countries includes extra tiles with accented French and German letters (11 blue and 11 red tiles).
No matter which version of the Words tile set you have, you can use accented letters when you create your custom album in Words Education (corresponding non-accented letter tiles will be recognized by the game as equivalents of the accented letters).
Please use the "All Languages" dropdown menu on the album search page to see some examples.
Find more information about custom albums in our PDF guide to the Words Education app.
