Queens was the warm-up.
LinkedIn Queens is a one-star Star Battle with the marking done for you. If it stopped being a challenge, you've already found the door. Star Battle is the real game behind it: bigger boards, two stars per region, and difficulty that goes as far as you do.
Your solve, replayed move by move.
When you finish, Zavija replays your solve, like a chess.com Game Review for Star Battle. It marks the moves where you were brilliant and catches the slips; it also shows you the moments you ground through a deep look-ahead while a simple count was sitting on the board. No other Star Battle app looks at your own solve.
A look-ahead, done in your head: column D collapses three moves out.
N-set on rows 3–4: regions A and F own them.
Works, but a one-step count at A2 had it. You took the long way around.
Breaks column F; it already had its two stars spoken for.
HINT · CONFINEMENT
Region D is trapped in row 6.
Every open cell left in region D sits in row 6, so one of them must take the row's star. That means no other region can put a star in row 6: clear the rest of the row.
Get better every solve.
Stuck isn't a dead end. Ask for a hint and Zavija names the technique and walks you through why it works, so the next time you find it yourself. It's a teacher, not a solution button. Hints are free and unlimited.
And when the logic runs deep, so does the hint.
A hard deduction can stand on two separate facts. Zavija's hints walk them one at a time. Every claim carries its own Why?, and each Why opens the reasoning beneath it, down to ground you already trust. This one is a real hint from a real 10×10.
HINT · A REGION, PINNED DOWN
G10 and G7 can't hold a star. Clear both.
Rows 8–9 still need 3 stars. Outside G8/G9 their open cells split into two zones that hold one star each, so the third must sit in G8/G9.
Columns E–F still need 3 stars. Outside those four cells the rest splits into two one-star zones, so the last star sits in the pairs.
That's both of region C's stars accounted for, so its other cells can't hold one. G10 and G7: eliminated.
Big, hard, and graded by a real engine.
Most Star Battle apps stop early and call everything either "normal" or "hard." Zavija goes bigger and harder, and it tells you why a puzzle is hard before you start: the techniques it demands, how much hunting it takes, how deep it goes. And it never runs out.

Questions, answered.
What is Star Battle?
A logic puzzle on a grid split into regions. Place stars so every row, every column, and every region has exactly two, and no two stars touch, even diagonally. Pure deduction, no luck. (You may know its 1-star cousin as LinkedIn Queens.)
Do I need an account?
No. Play, solve, and see your review with zero sign-up. An account just saves your progress across devices and unlocks the library once you buy.
Is it really one payment?
Yes: $7.99, once. No subscription, and nothing expires.
Are there ads?
None, anywhere. Not on the free tier, not between rounds. Zavija is funded by a single optional one-time purchase, so the game's only job is to be worth playing. (Coming from an ad-heavy puzzle app? Here's the comparison.)
What's the review?
After you solve, Zavija walks through your own solve: the brilliancies, the slips, and the easier lines you missed. Think of a chess.com Game Review, for Star Battle.
Does it work on my phone?
Yes, it runs in any modern browser, phone or desktop. (Native apps may come later.)
¿Está en español?
Sí, Zavija está en inglés y español.
