The click click game you describe is a quick reflex game that requires players to click on boxes containing the letters "X" or "O" within a certain amount of time. Here's how this game works and the rules:
Interface: The screen will display a square grid containing randomly appearing "X" or "O" letters.
Time limit: Players will have a short amount of time to click on the boxes with the letter "X" or "O" as required.
Difficulty: As time passes, difficulty can be increased by decreasing reaction time or increasing the number of boxes to press.
Score: Each time the player correctly clicks on the box with the required letter, they will receive points. If you press the wrong button, the game ends.
