Super PonGoal

The ball runs back and forth between two paddles on a narrow pitch. There are only a couple of controls, but the timing is tight enough that a fraction of hesitation lets it slip past you. Short sessions decided purely by reaction.

Because everything comes down to hand speed, this turns out to be an uncomfortably honest read on your own condition. A well-rested afternoon and a sleepy one produce visibly different scores without anyone having to point it out. Some people use it as a signal that it is time to stand up and take a break.

One small habit genuinely helps: stop watching the ball and watch the opposing paddle instead. The return direction is decided the instant the ball meets it, so reading half a second ahead is worth more than moving twice as fast once the ball is already travelling.
