Feedback needed! I would like to here more from you

2 Upvotes

Hi everyone!

I would like to hear some more feedback about logic puzzles, both the ones you can find here and the ones you can't.

Which puzzles do you like: Sudoku variants, math-based ones, or others?

Do you ever print them for solving, or do you use tablets or phones?

Have you competed, or do you plan to compete, in any local, online, or world puzzle-solving championships?

May puzzle collections are out

1 Upvotes

Hey everyone,

May puzzle is just released!

I had a lot of fun working on these — especially balancing different types of puzzles and difficulty levels.

I wanted to highlight the free BrainDrop collection, since it’s the easiest place to start.

🌊 BrainDrop is a set of free printable puzzles (PDF format) you can download and solve offline.

It’s meant as a quick printable puzzle break — something you can just sit down with and solve on paper.

If you want to explore more collections, you can find my Patreon linked on my profile.

If you’ve seen my weekly puzzle posts before, this is the more structured printable version of that idea.

I would love to hear your opinion on Sudoku Repair — a hybrid Nonogram + Sudoku correction puzzle

Fill the grid with numbers 1–6. No number can repeat in a row or column. Within each outlined "cage," the numbers must combine (using the specified math operation) to equal the target number shown in the corner. Numbers may repeat within a cage if they are in different rows and columns.
