This is the second 9x9 shikaku-sudoku puzzle I made. The first puzzle can be found over here.
Normal sudoku rules apply. Additionally:
Here is an example:
An easier 6x6 puzzle to get familiar with some of the logic is this:
The main puzzle:

A very satisfying solve, even with the latter classical part. An interesting and inspiring variant. Thanks Qodec :)

I did not expect the given 8 and 7 to do so much work in resolving the Shikaku clues. Thanks for the nice puzzle.
The regular sudoku at the end is not easy. It's not too hard after a lot of hidden pairs and a certain naked single, but it's a little bit harder than a variant puzzle should be.
EDIT: I apologize, I did not realize it was Qodec who made this puzzle. In which case this is the perfect difficulty for a variant puzzle. Please don't make it even harder.
@Silverstep Haha no need to apologize. Tbh I couldn't resist that naked single after I spotted it... the temptation was just too high! I hope next time I'll be stronger. :)

Very enjoyable shikaku logic and the resulting classic is slightly tricky but doesn't require anything harder than scanning for pairs and triples (overall felt like 4 stars difficulty for me). Thanks! :-)

The tiling was challenging and fun. The resulting sudoku, on the other hand, was unreasonably hard for my taste and felt much like a chore. Requring advanced sudoku technique (anything more fancy than bent triple) in a variant sudoku is overkill in my book.

Hope I don't find an alternative tiling again. :D
@henrypijames Haha I hope so too! But I guess that if it happens again I'll just have to keep practicing and make a third!
