Repair a blocked-paper shortcut · own paper
Whole supplied source
Fictional paper scene: Secret-caption repair. Columns A to D run left to right; rows 1 to 4 run top to bottom. The 4 by 4 grid has equal cells. One move reaches one neighbouring cell, with no diagonals. Up/down refer to this page’s top/bottom, not a person’s facing direction. Start B4; target D2. Closed cells: C4. Never enter or pass through them. The proposed instruction is 2 cells right, then 2 cells up. This is supplied fiction, not an observed journey or real-world distance.
