About Count the Cubes
A little building of blue cubes appears, drawn in 3D. Your child counts every cube, including any hidden ones that hold up the cubes on top. Towers never get taller toward the front, so every top stays in view.
How to play
- Count the cubes you can see in the building.
- Remember the hidden cubes under and behind the others.
- Tap the total, or press number keys on a computer, 1 for the first answer.
What your child practices
