Key constraints
Anchor the tightest regions first
Single-cell sums, zero targets, and strict greater-than or less-than regions usually eliminate most dominoes.
Track domino inventory
Every domino appears once. If a number is rare in the tray, protect it for regions that cannot use alternatives.
Verify both halves
A domino placement only works when both covered cells satisfy their region constraints and adjacency.
Pips placements come from NYT official puzzle data.
