Queens was the warm-up.
LinkedIn Queens is a one-star Star Battle — colored grid, two minutes, auto-marked. 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 celebrates the moves where you were brilliant, catches the slips — and 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.
Big, hard, and graded by a real engine.
Most Star Battle apps stop early and call everything either "normal" or "hard." Zavija goes bigger, goes harder, and 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 math, 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, no ads, nothing expires.
What's the review?
After you solve, Zavija walks through your own solve — the brilliancies, the slips, and the easier lines you missed — like 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.)
