Simon Blitz takes a familiar idea and tunes it until it clicks. Here you get patterns that speed up every level, down to 160 ms per flash, wrapped in a clean, distraction-free board that works just as well on a phone as on a laptop.
Best level is saved locally, so the game quietly turns into a personal duel. The gap between your level 12 and your level 15 is usually one silly tap - which is precisely why one more round always feels justified.
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.
Repeat the light pattern. It speeds up every level.
There are 5 close relatives of Simon Blitz in the catalogue, which is unusual here. Comparing it with Simon Sprint takes about a minute and tells you more than any description.
Difficulty sits at Hard and the player count at 1. Those two numbers decide more about whether you will enjoy it than the theme does.
Keep it if you play in short bursts. It rewards a second attempt far more than a first, and the second attempt costs nothing but the tap.
