As answered by people managing React Tutorial and Meowdoku.run.
Meowdoku.run's answer:
Meowdoku takes the classic Sudoku you already know and wraps it in a calm, cat-themed design that's actually pleasant to sit with. Most online Sudoku is either cluttered with ads or stripped down and ugly — Meowdoku is built to feel cozy. It runs entirely in the browser, loads instantly, and never asks you to create an account before you can play.
Meowdoku.run's answer:
No signup, no app install, no ad walls between you and the next puzzle. You open the page and you're playing in seconds. The cat theme and clean layout make it a genuine 5-minute mental break rather than a chore. It's free, it works on any device, and it respects your time and attention — which is more than most free Sudoku sites can say.
Meowdoku.run's answer:
Casual puzzle players who want a quick, relaxing brain break — people doing Sudoku on a coffee break, commute, or between tasks. It skews toward anyone who finds classic logic puzzles calming and happens to like cats: students, office workers, and older puzzle fans alike. No prior Sudoku experience needed; easier levels welcome complete beginners.
Meowdoku.run's answer:
It started from a simple combination: I love Sudoku and I love cats, and I was tired of online Sudoku sites that buried the game under ads and signup walls. So I built the version I actually wanted to play — clean, cozy, instantly playable, with a cat theme that makes a quick puzzle feel like a small treat. Meowdoku is that idea, shipped.
Meowdoku.run's answer:
Built as a lightweight browser game with Next.js / React on the front end, deployed behind Cloudflare for fast global delivery. The Sudoku generation and solving logic run client-side so puzzles load and respond instantly with no server round-trips.
Meowdoku.run's answer:
Meowdoku is a free consumer puzzle game played by casual Sudoku fans worldwide — it doesn't have enterprise customers.

I just wanted to know if anybody took both or the react-tutorial.app course. I mostly like the flashcards part of the course. I was thinking of taking the Scrimba course and just using the other courses study materials. Source: about 3 years ago
The Jad Joubran courses on the other hand really upped my skill level and helped me make the jump from passive learning, exercises and very small projects to making legitimate web apps. That was probably the biggest/scariest jump I've... Source: over 3 years ago
I learned through https://react-tutorial.app/ and absolutely loved it. I'm also a hands-on guy. Source: over 3 years ago
