Jenny (Tommy Tutone, 1981)

The puzzle shows Jenny has a rotary phone? Normal Sudoku rules apply. KROPKI PAIRS- Numbers with a white dot between them are consecutive. Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. KILLER CAGES- Numbers in cages sum to the number in the top left corner of the cage. HINTS: Look up the song "Jenny". I use 4 in place of 0 for Jenny's telephone number in the song in three rows. SPEED RUN- If you know the song or look it up: Bonus for less than 12 Minutes, Double bonus for less than 10 minutes. Post your time on Logic Masters Germany, if you like.
