OO7 Game
This HTML file contains the implementation of an OO7 game using pictograms for smartphones and tablets. The game board consists of a 4x4 grid, where each cell can either contain a bomb or be empty. The player's objective is to avoid revealing the bombs by clicking on the cells. The game supports revealing cells by tapping on them, and the state of the game board is updated accordingly. The visuals are represented using pictogram images.
Please note that the pictogram URLs (`bombUrl`, `targetUrl`, `emptyUrl`) in the code should be replaced with actual image URLs for the game to work correctly.
