It’s a nice puzzle, but because the two dominoes only have one fixed orientation some of the puzzles end up being a little too easy as the blocked spaces strongly limit the possible tilings. I think I did at least one without having to look at the row and column counts.

If you’re trying to make this a daily thing then I think I understand that decision on difficulty, and I may have played too many games of magnets in Simon Tatham’s puzzle collection so I may not be your target market. :-)
