Practise: Sashimi Fish

Follow one digit only: where is a Fish corner missing, and which note disappears in that same box?

The prepared notes show an incomplete Fish. One base line has just one corner and a fin. Check their shared box; do not place a digit yet.

Your turn first

Where can 6 no longer stay?

In the prepared 6-notes, first find the almost-complete Fish with one missing corner. Then find the fin in the same box. Only there can another 6-note disappear.

Remember

A Sashimi Fish is an incomplete Fish: one corner is missing while a fin sits in the same box. Therefore only the matching cross-line in that box is fixed, and only there can the digit be removed.
