XO Kings - Flutter Tic Tac Toe Game

XO Kings is a complete Flutter Tic Tac Toe / XO game template designed with a modern neon-style mobile interface and multiple ready-to-play game modes. The game includes Play vs AI, Play vs Friend, Coin AI mode, and a progressive Level Game system. It also includes player statistics, coins, inventory, X and O color customization, avatars, skins, sound effects, and a clean mobile user interface. This source code is made for developers who want a ready-to-customize Flutter game template.

Buyers can change the app name, logo, package name, colors, assets, coin values, store items, avatars, skins, and game branding easily. The package includes detailed documentation explaining how to install the project, run it, build a debug APK, customize the app, connect Firebase, and prepare Google Play Billing if needed. The marketplace version is prepared as a clean template. It does not include private Firebase keys, Google Play Console credentials, payment secrets, service account files, or private backend keys.

A local demo account is included for testing, so buyers can run and test the project before connecting their own Firebase or Google Play Billing setup.
