Why kids like it
Figuring out the blocks you cannot see makes kids feel like little engineers.
How many blocks are in the pile? Don't forget the hidden ones. This game builds 3D spatial imagination by asking children to infer unseen blocks. Across 100 levels, the stack grows from a small single layer to deeper layouts and taller columns, with a steady challenge for spatial reasoning. Train your 3D brain at xiguasmart.top!
