While Cubroid is recommended for kids between the ages of 5 and 12, younger kids can enjoy Cubroid under adult supervision, and older children can enjoy it paired with Scratch program (8-16 years old).
Module blocks need to be charged with a USB cable, but you don't need to charge the shape blocks. The blocks communicate each other via built-in Bluetooth connection.
Once you charge the blocks for 2 hours, you can use them freely for 6-8 hours. If blocks are left powered off, you can use them after two months.
