* Proper layout of the board (need spacing to separate mini grids
from each other).
* Move restrictions: Don't allow a player to move in a super grid
that doesn't correspond to their last move's mini-grid placement
(unless the corresponding super-grid is full).
* Presentation to the user of the scored glyph shapes
* Scoring of completed mini grids
* Scoring of the super grids for the final game
And on that last point, there needs to be an option to play either the
"majority" or "super-glyph" variation for the final scoring.
