Train reflexes and short-term memory with reaction-time timers, number and sequence memory challenges, and light mouse games. Times are measured in your browser with millisecond resolution.
Use F1 start-lights mode for a familiar racing cue, or open the Games hub for runner and puzzle titles.
Reaction tests measure how quickly you respond to a visual or audio cue, reported in milliseconds. Memory games stretch digit span and sequence recall; whack-a-mole and the Games hub add lighter practice.
Scores improve with focus and a consistent setup — same device, same input, few distractions. Treat them as training tools, not medical diagnostics. F1 start-lights mode mirrors the race grid cue many drivers know.
