So, at first I didn't like this game. Because to resolve the green queen placement, I had to resort to proof by contradiction. Which is less satisfying than a direct proof.
Spoiler: But, then I found a very cool application of the touching rule. For one of the greys.
First, eliminate all but 2 of the greens.
Next, use the cover 3 rule to eliminate some grey.
And now, this is the neat part, one of the 4 remaining greys is touched by one color and so can be eliminated. I leave to you to find the grey and the color. But, its elimination leads to a revealed cover 2 rule, which blows the game wide open.
Confession: I do the puzzles offline and then review my work. In this puzzle, when I reviewed by placements, I realized that although I got the right result, I had made an error in reasoning. Just luck that I wasn't wrong. Had I not reviewed my work I wouldn't have found the cool touching application.
Always be reviewing.
