A QUICK START

One board. Everything fits.

  1. Tap a domino to rotate it. Each tap turns it a quarter turn clockwise. Each half fills one cell. A blank is zero.
  2. Drag it onto the board. You can also tap a cell for its first half. Keep tapping the domino, use Rotate, or press R to turn it again.
  3. Follow each region’s rule. Dominoes can cross region borders. Every domino must be placed and every region satisfied.

Tap a placed domino to select it, then rotate, move, or return it to the tray. Use Undo freely. There is no timer limit or penalty for experimenting.

Hints highlight a region, explain candidate eliminations, reveal a move, then place it. Revealing the full solution ends the board as practice.

Keyboard: Tab between controls, arrows between cells, Enter or Space to select/place, R to rotate, Escape to deselect.

Less-than conditions are strict. For <5, a total of 5 fails. Zero is useful: it fills a cell without increasing the sum.

Most regions use the selected practice rule. Single-cell regions use exact values to keep the board approachable. Practice boards have no time limit and do not affect your daily streak.
