Normal Sudoku rules apply.

KROPKI - Digits separated by a white dot have adjacent values.

BETWEEN LINES - Digits on grey lines must have values strictly in between the values of the digits in the attached circles.

LOOK AND SAY LINES - Digits on grey lines (not including the circles) are "look and say" clues for themselves when read in one direction. For example, if the digits on a line read "1234" it would mean either that the line has one 2 and three 4s on it, or that it has four 3s and two 1s on it (which are both wrong, so 1234 is not a possible line).
