Frequently asked questions

How do I play?

Place one star in every row, every column and every colored region. Stars can never touch, not even diagonally. Comets also claim the squares a chess knight's move away, and pulsars also claim both full diagonals. Tap a square to mark it ✕, double-tap to place a star, and drag across squares to mark several ✕ at once.

How do hints work?

A hint highlights the next logical move and explains why it works. Reveal places one correct star for you. Both cost stardust.

How do I get more stardust?

Solve levels, collect the daily reward and the weekly chest, watch an optional reward video, or buy a stardust pack in the shop.

I bought Remove Ads. How do I get it back on a new phone?

Open Settings → Restore purchases while signed in to the same Apple ID or Google account you bought it with.

I reinstalled the app and lost my progress.

Progress and stardust are saved on your phone only, so deleting the app removes them. Remove Ads can be restored (see above). Stardust packs are used up when bought and can't be restored.

Why are some leaderboard players marked "AI"?

They're computer rivals that keep the board lively while the community grows.

When does the leaderboard reset?

Every day at midnight UTC.

How do I change my leaderboard name?

Open the leaderboard and tap Change name.

How do I change ad privacy settings?

Open Settings → Ad privacy choices. On iPhone you can also change tracking permission in Settings → Privacy & Security → Tracking.

How do I ask for a refund?

Purchases are handled by Apple or Google:

How do I delete my data?

Deleting the app removes everything stored on your phone. Leaderboard entries are deleted automatically after 30 days. To remove them sooner, email support@nitroedgestudios.com with your leaderboard name and the day(s) you played.
