Layer Switching
Mandala App has a two-layer structure that composes a 9x9 type chart from a 3x3 type chart. Each of the 8 squares around the top will expand to 8 more squares. To expand, tap the alphabet of the cell you want to expand, and the lower layers of that cell will be expanded.
Tap the alphabet icon in the center cell of the lower layer to return to
the upper layer.
