I don't know if there is a rating for number of steps without a Hidden Single / Direct, but the following puzzle has 24 givens, and 57 Hidden Singles. The fun part? in the middle of the solution sequence you have 13 steps in a row that with difficuly ranging from Pointing up to Unique Rectangle. ie 13 steps before you can write a value in a square.

Code: Select all
821000007

307002000
009000002
500401000
280000000
040080000
008040730
