Welcome to the fun of playing air hockey online with Stack Sorting! Your task here is akin to organizing colorful pucks on an air hockey table. Click on stacks as you would control a mallet, moving the topmost cylinder, representing a puck, to an empty stack or one with a matching top. You can navigate through Easy Mode, which offers plenty of stacks and time, or challenge yourself in Hard Mode, mimicking a high-intensity air hockey online match with fewer stacks. Complete all levels within the time limit to emerge victorious, just as you would in a gripping game of air hockey online!
