Straight to the point: Bomb Bonanza is a 60-second round with 22% bomb rate, playable in your browser right now. It is tuned for quick runs, honest difficulty, and controls that make sense the first time you touch them.
Targets pop up for a fraction of a second and vanish; hit the good ones, skip the bombs. Miss a target or tap a bomb and you lose one of three lives. The a 60-second round with 22% bomb rate, so the difficulty is front-loaded into reflexes rather than memory.
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.
