Very large killer cages (7–9 cells)

Cages of 7, 8, or 9 cells are mathematically valid but rarely appear in real puzzles. We collect them on this page rather than dilute the standalone catalog with thirty thin entries.

An 8-cell cage forces the cage's missing digit; a 9-cell cage is the entire row, column, or box, which solves itself. The reference value is in seeing the complete table at a glance.
