Pong Giants is a browser game built for short, satisfying sessions - it loads instantly, plays with one thumb, and runs on any mid-range phone. The setup is simple: first to 7 goals, paddle at 30% of screen height. Nothing to install, no account, no waiting.
Two paddles, one ball, 7 points to win - it is the oldest video game argument, settled locally. Solo mode puts a CPU on the right side with adjustable error; two-player mode shares one screen and one very tense sofa.
Nothing here needs a tutorial or a wiki. Controls are one gesture, the goal is one sentence, and the difficulty comes from execution rather than homework. That is exactly what a browser game should be.
