Every move matters
City games use best-of-three series. When every round draws, move quality comes first, followed by average thinking time. An exact tie refunds entry and offers a rematch.
Online search waits ten seconds for another player. A computer-controlled rival can join when no player is available. Guest city games use computer-controlled rivals.
Google sign-in, clearly explained
Google sign-in uses your basic account identity: name, email, profile information and account identifier. XO Arena does not receive your Google password or request access to Gmail, Drive or contacts. Online account and game records use Supabase.
Guest practice coins, gems and cosmetics stay on the device and are separate from the online ranked wallet. Read our Privacy Policy for storage, sharing and deletion choices.
Optional rewards. Virtual coins.
Optional rewarded ads offer up to ten completions per day, with a 20-gem bonus at the tenth completion. Coins and gems have no cash value. Release builds can use Google AdMob rewarded ads; optional gem packs may be available through Google Play when enabled for your region. Account gems can unlock cosmetics or exchange for online coins. Ad availability depends on account approval, consent and inventory.
Signed-in rewards are credited only after server verification of an eligible completed ad. Our Terms of Use describe rewards, fair play and feature availability.
