What do children learn in the Cube course?
The multicolored cube looks difficult, but the solution for beginners is actually a few short, repetitive rotations. Karotto teaches in three stages, each stage reuses what the child has learned in the previous stage:
What is the "spell"?
Each rotation sequence is named and divided into short rhythms for your baby to read aloud like a rhyme. For example, "Rabbit Rhythm" has 4 beats: right up, top left, right down, top right. The child learns the beat first, then learns when to use it, instead of having to remember the letter symbols.
What does a lesson look like?
The child always preview: the 3D block on the screen rotates each beat, with the beat name clearly visible. Then the child makes it himself on the block in the app, or follows it on the real block he is holding.



Solve your child's real block
Children can color their real block into the app, one side at a time. The app reads that state and shows how to solve each step according to the method and spell the child has learned, so the solution is not a strange sequence but a rhythm the child is familiar with.
Why can the child learn on his own?
- Voice reads out loud: The robot's instructions and prompts are read aloud, available in Vietnamese and 12 languages. other languages.
- Preview and then do: Each spell has a sample animation, children can watch it as many times as they like.
- The robot suggests 3 steps: level 1 lights up the face to be rotated, level 2 shows the rotation direction arrow, level 3 brightens Spell card to use.
- Small steps, see immediate progress: each lesson shows a goal like "white plus sign" or "a corner in place", then there are stars and stickers.

Frequently Asked Questions
At what age can a child learn to rotate a cube?
Many 5–6 year old children can already learn the 2x2 cube if given step-by-step instructions. 3x3 blocks are usually suitable for children from 7 years old, while 4x4 is for children who have successfully solved 3x3.
Do I need to buy real blocks?

Which size block should I buy first?
