  • Drag to place; each domino covers two adjacent cells (no diagonals).
  • Tap a domino in the pool to rotate 90°; dragging uses current orientation.
  • Instant checks highlight conflicts; use Undo/Redo freely.
  • Switch Easy/Medium/Hard anytime; clear to restart.

This fan-made site focuses on a minimal, mobile-friendly experience for learning, practice, and daily play. Not affiliated with The New York Times.

EQUAL (=)

All half-cells in the region must have the same value. Tip: for 2-cell regions, a double (e.g., 3|3) often fits.

ALL DIFFERENT (≠)

All half-cells in the region must be pairwise different (no repeats).

SUM = n

The sum of values in the region must equal n (e.g., =7).

SUM < n / SUM > n

The sum must be less/greater than n (e.g., <4 / >10).

Single-cell + number ≡ ‘this cell must be that number’. Each region has exactly one badge; rules do not stack.

Cells without a rule badge (NONE) are not outlined with dashed borders and accept any value.

  1. Start with certainties: single-number cells and 2-cell ‘=’.
  2. Lock in ‘=’ regions early to reduce branches; doubles help.
  3. Work sums/inequalities next; prune overshoot/undershoot combos.
  4. Tackle ‘≠’ later when conflicts are easier to spot.
  5. Use Undo/Redo to explore branches without fear.
