Counterproductive

Rules:
Normal sudoku rules apply. A cage's product (the result of multiplying its digits together) exactly equals the number of cages with that product. Note: if a cage has only one digit, that digit is considered to be the cage's product.
Lösungscode: Column 5 reading downwards

Very cool concept from one of my favourite constructors!

Great puzzle! Very hard for me but very satisfying. For a long time I was not sure, that my approach was correct. But everything came together nicely in the end. Thanks Marty!

That was a really, really, really, really good puzzle. Took me 1h10m but felt like just 10 minutes (that's a lie it felt like forever). Thank you.

Brilliant!

What a fantastic puzzle! It took a lot of me to appreciate all that could be used and I enjoyed every second of it. Your setting never ceases to amaze, Marty! Thank you for this wonderful and fun construction!

Pfew! Finally, after trying and giving up for days, I managed to figure it out. Not with any big break, just lots of small things about allowed products and such.
Now off to Simon's video to see if there is a more straightforward break-in.

Thanks for the puzzle ^^

This was really awesome. For me it was quite hard, maybe 4.5*. (I likely overlooked some very elegant solve paths.)

I liked this one a lot! I think I went on the solve path Marty intended, and it didn't really need much math. A couple of the possible constraints revealed themselves, and then i could do passes through the puzzle one digit at a time. There were a lot of beautiful a-ha moments!

Exellent. This is just what I keep returning to Marty's puzzles for whenever I spot them.

Great puzzle with a well-executed idea and smooth, logical flow. I really enjoyed the break-in as well!

Top top puzzle!

This felt more like a brainteaser rather than a sudoku. In sudoku it often (especially with your magical setting) feels like the puzzle is underconstrained so you slowly chip away until you can deduce a unique solution. In this case the puzzle felt overconstrained. I realised quite quickly what the solution should look like, but I could not make the digits fall in place for a long time. Once I finally did though the puzzle was oh so smooth. Thanks for the lovely setting!

Great puzzle, and interesting variation on counting circles.

What a marvellous puzzle. Got stuck in a mental cul-de-sac for a bit but everything fell into place beautifully.

A simple idea, perfectly expressed

absolutely lovely, a great series of little deductions to narrow things down and understand the puzzle just a bit more until everything clicks into place and there's numbers agogo

It's a lot of fun to see a seemingly wide open field of possibilities slowly whittled away to leave just one set.

I really enjoyed it. Thank you. :)

Interesting twist of your Counting Circles presented in perfect setting. So much fun! Thank you very much for creating and sharing this beauty.

Feels like after the first few deductions that it’s just a matter of finding the right orientation, but then this puzzle has a few more great surprises in the middle! Lovely execution on this idea.

Very cool puzzle, quite easy to get lost a bit in chains of reasoning that aren't the way forward, but eventually there is always a reasonable step forward to be found.

What a lovely solve path! Thank you!
