10 minutes was about what it took. Cool to have four different puzzles with the same starting grid.

Very nice puzzle, but it took me one hour.

@ScattlerBrain & @meowzzz: With the word "clue" I meant individual objects in the grid while a sentence under the heading "Rules" would be referred to as a "rule". I hope that the rephrasing of Puzzle 4 text removes the ambiguity.

Clarified the description of Puzzle 4.

As @ScatterBrain has pointed out, the last puzzle wording a bit confusing. Might want to rephrase a little, something along the lines of differentiating between the word rule and clue.
Puzzle 1: all rules are correct
Puzzle 2: all rules are lies
Puzzle 3: either:
a) white dot rule is a lie
b) black dot rule is a lie
c) both white and black dot rules are a lies
Puzzle 4: only a single CLUE (not the entire rule) is a lie
