Grid Sum – Medium

Organise your arithmetic. Medium grids often involve larger numbers or multiple operations.

  • Keep additions tidy.
  • Subtract carefully from totals.
  • After each placement, reassess the grid for new single-blank lines.

Key idea: progress compounds — each solved cell reduces complexity.
