How accurate is your internal clock? Start and stop without a visible timer in ten free rounds with changing durations, distractions and hold-and-release timing.
Read the target duration. Use Space or the button to start and stop. In later rounds, hold the control and release it when you think the target time has passed.
Changing durations test your internal clock first. Irregular visual distractions follow, then hold-and-release rounds combine attention with timing.
The changing symbols are deliberately irregular. They are distractions, not a clock. Use the early-or-late feedback to adjust your next attempt.
Ten rounds add up to an Instinct Score of 0–1000. Round limits rise from 40 to 220 points. Instinct’s Core separately measures how accurately you predicted your rank; it waits for at least 30 other comparable attempts. These games are informal benchmarks, not a diagnostic assessment.
