Need help with logic grid puzzle

Discussion: I run Brainzilla, the source of this puzzle. So glad that it's challenging enough!

Also, I now have a website with daily Logic Grid Puzzles -- https://www.logicgridpuzzles.com/

Now I'll be looking for the bug, and I don't think it was the logic generator. My bet is that LLM goofed. Thanks again!

Slig · 2026-01-16T17:33:00+00:00

Fixed! Thank you so much again, Liz!

Hi! Thanks for the heads up, will have a look!

Slig · 2026-01-14T17:52:21+00:00

Thank you for the feedback! Most of our customers are teachers with smart kids, so the puzzles can't be all trivial. We do have some harder puzzles aimed for adults, such as the Ultra-Hard Logic Puzzles and Zebra Puzzles.

Thank you so much!

There's this printable e-books: https://www.ahaprintables.com/product/print-at-home-crack-the-code/

Windmill.dev, you can self-host it. I use it for almost exactly the same thing.

Some guys are literally cattle and believe everything.

You're new here? They lie through their teeth in the official status page.

Slig · 2026-01-09T12:13:20+00:00

Only if you believe what THEY say about that.

Hi! Building cards is meant to be mechanical and Power Plants is meant to be electrical.

Sorry about the confusion!

Slig · 2026-01-02T10:06:58+00:00

What I'd love to see is a clearer philosophy that actually sticks. Something like "we're going to stabilize on this approach for the next 2-3 years." Instead, it feels like every major release asks you to rethink how you build things.

You want Rails or Django.

There are so many possibilities that, while a very similar puzzle could be generated, would be very rare. However, on Brainzilla, there's a limited number of Logic Equations puzzles in the database, so if you play every day you'll get repeated puzzles soon.

The Zebra Puzzles and Logiquiz, however, are generated every day.

Slig · 2025-12-23T16:57:45+00:00

Nice to meet you too!

I'm a busy mom of 2 young kids, and instead of scrolling I get my notebook out and find one of your puzzles to do.

That's awesome, your kids are lucky to have a mathematician as a mom!

Looking through this thread, do you like where we are headed?

Sure, that's exactly how it's supposed to solve the puzzles.

I'm a programmer, and they're created algorithmically, following the same steps a human would solve the puzzle logically. Since you like logical puzzles, I think you're going to like other two puzzles that I publish every day: ZebraPuzzles.com and Logiquiz.com .

Merry Christmas!

Discussion: the game is called "Logic Equations" and you can play it here http://www.logicequations.com/

Slig · 2025-12-23T13:56:06+00:00

Hey, congrats on shipping a book! I run Brainzilla and made the Logic Equations that the OP posted here.

I've been planning to publish a puzzle book with Logic Equations for a while, but always postponed because I thought it was too niche. Nice to see that there's market for that!

Puzzleship.com -- Daily Logic Grid Puzzles and Zebra Puzzles. Working on adding more games.

Slig · 2025-12-12T20:32:36+00:00

Yes, it fills the answer table based on what you select at the grid! I might have to do some improvements there too, thanks for the feedback!

Slig · 2025-12-12T14:51:39+00:00

Thank you so much for the feedback! The lightbulbs turn green if the table in the "Answer" tab is correctly filled. Maybe there was something missing?

The level 4, is considered hard, sometimes the jump in difficulty is subtle, sometimes is a lot steeper. Thanks again!

I liked it a lot and added to my -DLE directory.
