In Osmo ABCs, kids build letter shapes and pictures of objects out of silicone sticks and rings. The game teaches literacy skills to kids aged 3-5.
The Osmo ABCs app is available free of charge in all geographic locations and works on all iPads and Amazon Fire tablets that Osmo supports. The app requires the Osmo Sticks & Rings, and the Osmo iPad or Fire base to play.
