A Better Daily Sudoku

Free to play, clean interface, and a hint system that teaches you to solve — not just gives you the answer.

Puzzles Done Right

There are plenty of puzzle apps out there. Most start clean and slowly bury the experience under ads, forced accounts, and microtransactions for features that used to be free.

PuzzleProwl takes a different approach.

We're building the best version of each puzzle we offer — clean interface, mobile-friendly, free to play — and expanding the lineup one game at a time.

The Hint System

Most puzzle hint systems just solve the cell for you. That's not a hint — it's a spoiler.

PuzzleProwl's hint system has four levels. Use as little or as much help as you need:

Level	What It Shows
Region Highlight	The row, column, or box where a move is available
Cell Highlight	The specific cell you can solve next
Technique Hint	The technique name and the relevant cells
Solution Step	Fills one cell and explains exactly why

Every signed-in player gets one free hint per day. Token packs are available if you want more. Nothing is forced.

How We're Different

Most puzzle sites are built to maximize time-on-site and ad revenue. We're not.

Mobile-first — works on your phone, tablet, and desktop. Install as a PWA and it behaves like a native app.
Built by a player — every decision made by someone who actually plays these games
Honest monetization — one free hint per day, token packs if you want more, a Pro subscription for daily players who want ad-free plus a monthly token allowance. Nothing hidden.

Common Questions

Is PuzzleProwl really free? Yes. Core gameplay is always free. The daily puzzle, the full library, and all five difficulty levels cost nothing. The hint system offers one free hint per day — token packs are available if you want more.

Do I need to create an account? No — open the page and play. Sign in with Google or Apple to unlock the daily puzzle, puzzle library, streak tracking, and the hint system. Facebook sign-in is coming soon.

Does it work on my phone? Yes. Every game is built mobile-first. You can also install PuzzleProwl as a PWA from your browser — add it to your home screen and it runs like a native app on iOS and Android.

Will there be an app? The PWA already gives you a native-app experience on iOS and Android. A full Capacitor-based app may come later, using the same account and progress data.
