Ad-free by design
Same logic itch. Zero ads.
If you came here searching for a game like Meowdoku without the ads: Star Battle is a different puzzle, but it scratches the exact same itch. Pure deduction, no guessing, in rounds that fit a coffee break. And Zavija carries no ads at all. Not between rounds, not on the free tier.
Different puzzle, same brain
Meowdoku is a lovely idea, a cat-themed blend of Sudoku-style and Minesweeper-style deduction where every move is forced by logic. If that's the part you love, you're the exact player Star Battle was made for. The rules take ten seconds: place two stars in every row, column, and region, and no two stars may touch, even diagonally. That's it.
What you get for those ten seconds is a puzzle that runs from gentle warm-ups to boards that fight back for twenty minutes: counting arguments, forcing chains, look-ahead. Every one of them is solvable by pure deduction, never by guessing. When a round ends, Zavija replays your solve move by move and shows you the easier line you missed, like a chess.com game review.
Why there are no ads, and never will be
An ad-funded puzzle app has a problem: it earns money from your interruptions, not your satisfaction. Every "free" round is priced in seconds of your attention, and mobile players searching for a way to pay their way out of the ads often find there isn't one.
Zavija runs on the opposite model. The free tier has no ads and no account: a weekly puzzle, a rotating set of graded boards, with hints and reviews included. If the game earns it, there's a single one-time purchase ($7.99, no subscription) that unlocks the full library, every size and difficulty, forever. That's the whole business model. The game's only job is to be worth playing.

Making the switch in one sitting
- Start with an easy board. A small two-star puzzle plays in a few minutes and teaches the no-touching rhythm fast.
- Lean on the hint. It doesn't reveal the answer; it names the technique and shows you where to look, so the next one is yours.
- Read your first review. Watching your own solve replayed, with the easy moves you missed marked, is the fastest improvement loop in the genre.
Common questions
Is there a game like Meowdoku without ads?
If the pure, no-guessing deduction is what you're after, yes. Star Battle delivers the same satisfaction with more depth, and Zavija has no ads anywhere, including the free tier. Browser-based, with no account and no install.
Is Zavija really ad-free? What's the catch?
No catch: no ads, free or paid, ever. The game is funded by a single optional one-time purchase ($7.99) that unlocks the full library. No subscription. If you never pay, you still never see an ad.
Is Star Battle the same as Meowdoku?
No: different rules, same spirit. Meowdoku blends Sudoku-style and Minesweeper-style deduction; Star Battle is two stars per row, column, and region with no two touching. Both are guess-free logic. The full rules take two minutes.
Is it hard to learn?
The rules are ten seconds; the depth is optional. Easy boards feel like a warm crossword; the hard ones are genuinely hard. The techniques guide walks the whole ladder, and difficulty is graded so you climb at your own pace.
