Playing
How do I win?
Take every cell on the board. A cell explodes when it reaches critical mass, sending a dot in each direction and converting whatever it touches to your colour. Converted cells can explode in turn — that is the chain.
Where can I put my first piece?
Anywhere that is not directly next to an opponent's piece, diagonals included. Squares you cannot use are dimmed while you place. This keeps the opening from being decided before it starts.
Why are corners weaker than they look?
Every cell explodes at the same size, but a corner has only two neighbours, so half its blast falls off the board. Corners are cheap to hold and poor to attack from.
Language
Can I play in my own language?
The game is available in English, 한국어, 日本語, Deutsch, Español and Português (Brasil). It follows your device language by default, and you can override it in Settings → Language — useful if your phone is set to one language but you would rather play in another.
Rating and leaderboard
My rating did not change after a match
Only ranked online matches move your ELO. Bot matches, pass-and-play and private rooms do not.
My progress disappeared on a new phone
Progress follows the account, not the device. If you played as a guest, it stayed on the old phone. Sign in with Apple or Google on both devices and the rating follows you.
When does the weekly league open?
Automatically, once enough players have finished a ranked match in the same week. Until then the tab shows how many are still needed.
Purchases
I bought ad-free and the ads came back
Open Settings and tap Restore Purchase. Purchases are tied to your App Store or Google Play account, so use the same store account you bought with.
What does ad-free include?
It removes interstitial ads permanently, as a one-time purchase. Rewarded ads stay available if you choose to watch one for a spin — they are never forced.
Account and data
How do I delete my account?
Settings → Delete Account. It removes the account, rating and all game data immediately and cannot be undone. Details on the deletion page.
What do you collect?
See the privacy policy. The short answer: the campaign works offline as a guest, signing in is optional, and the ad SDK asks permission before using an advertising identifier on iOS.
Still stuck?
