Understand the aim
Shade repeated numbers while keeping black cells separated and all white cells connected. Read that aim before choosing your first action. Follow this game’s rules rather than another version’s.
Making your moves
- Click a cell to shade, mark or clear it.
- No unshaded number may repeat in a row or column.
- Black cells cannot share an edge.
- Check puzzle verifies duplicates and connectivity.
The controls to know
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Look at the feedback after the action.
An example before you play
Two identical unshaded numbers in one row cannot both remain. Your next round may have a different position, so inspect it before acting. Verify the rule before continuing.
Notice this detail
Removing every duplicate can disconnect white cells. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
