The case notes
When every Kropki dot is shown
All markers named in this lesson are shown. Watch a worked example, then try the idea in a puzzle.
Put it into practice
White: neighbours · black: double
White Kropki dots join consecutive digits. Black dots join digits where one is double the other.
No dot rules out both
Here the rules say all possible dots are shown. So an unmarked edge is neither consecutive nor a doubling pair.
No white dot: not 1 or 3
This cell is two. The cell below has no white dot, so it cannot be one or three: both would be consecutive with two.
No black dot: not 4
Four would be double two. There is no black dot either, so four is out as well. Read exactly which dot colours the puzzle says are complete.
