MieTsumi - 3D Block Play

Build, rotate, see through, and explore shadows with simple 3D blocks for spatial learning.

MieTsumi is a simple 3D block app for children and parents. Place blocks, change colors, rotate the view, and explore block structures from many angles. Children can play freely while learning how hidden blocks, top views, side views, and stacked shapes work. Transparent view, wireframe view, and antenna view help make invisible blocks easier to understand. Antenna view uses small vertical lines instead of numbers to show stack height, so children who are not yet comfortable with numbers can still count by looking. The full version unlocks larger grids, additional colors, shadow mode, photo saving, and more. In shadow mode, children can move the light and observe how the block shadows change. There are no ads, no account registration, and no tracking. MieTsumi is a small, safe 3D block playground for learning spatial thinking through play.
