How to Use This Page
Drag a domino from the tray onto the board, or tap a tray domino then tap two adjacent cells, to place it.
Tap an already-selected tray domino again to rotate it 90° before placing it; keep tapping to cycle through all four orientations, then deselect it.
Tap a placed domino to rotate it in place; drag a placed domino to move it elsewhere on the board.
Every outlined region shows a rule -- an exact total, "all equal," "all different," a greater/less-than threshold, or no rule at all -- that its own cells must satisfy once filled.
Once every cell in a region is filled, its outline turns solid with a checkmark if the rule holds, or tints with an X if it doesn't.
The board is solved once every cell is covered and every region's rule holds.
If you're signed in, leaving and coming back later picks up right where you left off.
Full Rules
Every domino must be used exactly once, covering two adjacent empty cells.
A domino can straddle two different regions at once -- each of its two ends counts only toward its own region's rule.
Scoring rewards a faster solve; giving up before finishing scores 0.
