⚡

LV1 — BASIC FLASH The screen suddenly flashes GREEN — click as fast as you can. Click before the flash and you'll get a TOO EARLY warning and the round restarts. 5 rounds, scored on average reaction time.

🛑

LV2 — GO / NO-GO Click on GREEN (GO!) — do NOT click on RED (STOP!). Trains your inhibition control, the ability to suppress the urge to act. 8 rounds: 5 GO + 3 NO-GO, graded on accuracy. 🔓 Unlocks after LV1 avg ≤ 450ms

🎯

LV3 — MULTI-TARGET A green square pops up at a random position on screen — click it fast. Trains spatial awareness and peripheral vision reaction. 6 rounds, scored on average time from target appearance to click. 🔓 Unlocks after LV2 accuracy ≥ 70%

🕵

LV4 — FAKE-OUT Some rounds include a YELLOW flash before the real GREEN signal. Only click on GREEN — clicking yellow is a false alarm and counts against your score. 8 rounds: 5 real + 3 fakes, graded on false alarm rate. 🔓 Unlocks after LV3 avg ≤ 350ms

🔥

LV5 — RAPID FIRE Five green targets appear one after another at random positions. Click each one immediately. Tests sustained speed under continuous pressure. 5 rounds, scored on average time per target. 🔓 Unlocks after LV4 false alarm rate ≤ 34%

FREQUENTLY ASKED QUESTIONS

Q: What is a good reaction time?

The average human reaction time is around 200–250ms. Regular gamers typically score 150–200ms, and elite esports players can react under 150ms. Your personal improvement over time matters more than the raw number.

Q: Can training actually make you faster?

Yes — research shows consistent practice shortens reaction time by strengthening neural pathways. Most people see measurable improvement within 1–2 weeks of daily training. The streak system is there to keep you coming back.

Q: Why does my reaction time vary so much?

Fatigue, caffeine, hunger, stress, and time of day all affect reaction speed. You'll usually perform best when alert and rested. Track your streak to find your peak window during the day.

Q: Is my data stored on a server?

No. Your personal best, streak, and session history are stored only in your browser's local storage. Nothing is sent to any server, and no account is required. Clearing your browser data will reset your progress.
