Grid Mark Clash overview

Grid Mark Clash is a local two-player Tic Tac Toe game built around the classic 3x3 grid. One player takes X, the other takes O, and they alternate turns trying to line up three marks in a row — horizontally, vertically, or diagonally. The game includes smooth win animations that play out when a player achieves a winning combination, making each victory feel satisfying rather than abrupt. Draws are detected cleanly, and a new round can be started immediately without leaving the screen. The app ships with four visual themes — two light and two dark — so players can match the look to their preference or lighting conditions. A 4-digit PIN lock is available for those who want to keep the app private on a shared device. No accounts, no internet connection, no subscriptions. Everything runs locally. Open the app, pick your theme, and start playing.
