Osmo Words is available for purchase worldwide on our website and through retailers, by itself, and as part of several kits and bundles:
All newer Words tiles have letters printed in lower case on one side, and in upper case, on the other. The classic Words tiles only have uppercase letters printed on one side.
Note that when you use the new tiles, letters in the Words app are displayed in both upper and lower case, as appropriate. When you use our classic tiles, letters are always displayed in upper case.
Plastic lowercase/uppercase letter tiles are available for sale as a separate item to educators. Please submit an online request here if interested in purchasing for your classroom: https://support.playosmo.com/hc/en-us/requests/new
