Pong Tiny 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 13% 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.
It suits anyone with a queue to wait in or a kettle to watch: students between classes, commuters, parents stealing ten quiet minutes. There is no meta-progression to lose and nothing to catch up on - a week away costs you nothing but a little sharpness.
