Using XO Arena
These terms apply to XO Arena, the Android board-strategy game operated by RookDevStudio. By using the game, you agree to these terms. If you do not agree, stop using it. Read the XO Arena Privacy Policy for information about data processing.
Use the app lawfully and involve a parent or guardian where your age or local requirements require permission. These terms do not remove rights you have under applicable law.
Guest play and accounts
Guest practice and local play do not require an account. Online features use Google sign-in. Protect access to your device and account. Do not impersonate another person or use an abusive display name.
Guest progress and cosmetics are device-local. They do not automatically merge into a ranked account wallet and may be lost if app data is removed. Ranked progress is associated with the signed-in account.
Matches, opponents and outcomes
The game offers Classic, Rush, Connect 4, Mega and Block modes. Cities show entry costs and win rewards before you start. Entry is charged once for a best-of-three series. A ten-second online search can be followed by a computer-controlled rival when no player is available; guest city matches use computer-controlled rivals.
Series are decided by round wins. If all three rounds draw, average move quality decides first, then average thinking time. An exact tie refunds entry and offers a rematch. Server validation controls online moves and settlement. Leaving a ranked match can count as a forfeit; connection failures and turn deadlines can affect outcomes.
Coins, gems and cosmetics
Coins and gems are virtual game units. They have no cash value, cannot be withdrawn as money, and are not an investment, cryptocurrency or real-money prize. City entry and reward numbers describe virtual game balances only.
Cosmetics change appearance and do not grant a competitive advantage. Practice cosmetics use the separate local practice wallet. Items and balances may change as the game develops; we will communicate material changes where appropriate.
Optional purchases and refunds
When gem packs are available, the Google Play checkout shows the price and currency before you confirm. Packs are consumable virtual currency credited to the XO Arena account signed in when checkout starts. Gems can unlock account cosmetics or exchange for online coins at the rate shown before confirmation. Current exchange rate: one gem for 100 online coins. Confirmed exchanges cannot be reversed through the app. Gems and coins have no cash value and cannot be withdrawn or redeemed for money. Google Play handles purchase cancellation and refund requests under its applicable policies and consumer rights. A refunded or reversed purchase can remove the associated gem credit; if the gems have already been spent, gem spending can be restricted until the outstanding balance is settled. Contact support with your player code and order identifier if a purchase is missing; never send passwords, card details or purchase tokens.
Optional rewarded ads
Rewarded ads are optional and depend on availability and a successful completion callback. Early closure, failed loading or invalid verification does not grant a completed-ad reward. The daily allowance is ten completed rewarded ads, resetting at midnight India Standard Time.
The current reward design has a 90% coin reward chance (50–1,000 coins) and a 10% gem reward chance (1–30 gems), plus an additional 20-gem bonus at the tenth completion. Random rewards are not a guaranteed individual prize. Test-ad rewards remain local; live online rewards require valid server verification.
Fair play and acceptable use
Do not cheat, exploit bugs, automate gameplay to abuse rewards, tamper with balances, evade access controls, harass players or send unlawful content. Use room codes and friend features responsibly.
We may restrict abusive activity or invalid rewards to protect fair play and service integrity. Contact support if you believe an action or settlement is incorrect.
Availability and this version
Version 1.0.0 supports guest offline play and connected online features. Features vary by connectivity, device and service availability. Optional fixed-quantity gem packs may be offered through Google Play when enabled in your region. Paid passes and paid tournaments are not offered. Viewing a reward or cosmetic does not make a real-money purchase.
Service interruptions, updates and defects may occur. The game and third-party services are provided as available, subject to rights that cannot be excluded by applicable law.
Game content and services
Game artwork, interface, sound and other content are owned by RookDevStudio or used under applicable licenses. You may use them through the game for personal play. Do not redistribute the app or its assets as your own product.
Google, Supabase and advertising services have their own applicable terms and privacy policies. XO Arena does not receive your Google password.
Leaving the service and support
You can stop using the game or sign out at any time. Signing out or uninstalling does not delete online records. Follow the account-deletion request instructions to request removal of an online account and associated data.
For gameplay, reward, account or privacy help, email rookdevstudio@gmail.com with the app name, player code, device and a description of the issue. Never send passwords or sign-in codes.
