ABOUT REACTION TIME TEST
⚡ What Is a Reaction Time Test?
A reaction time test measures how quickly you respond to a visual stimulus — from when your eyes detect a signal to when your hand clicks. Results are in milliseconds (ms). Average human reaction time is 200–250ms, while elite gamers achieve 150–200ms.
Our free online test runs 5 rounds, gives ratings from Slow to Legendary, and shows your best, average, and score. No download needed — works on any browser.

💡 How to Improve Reaction Time
Sleep: Even 1 hour less sleep adds 50ms+ to reaction time. Practice: Daily reaction tests build neural pathways over 2–4 weeks. Gaming: Fast-paced FPS games (CS2, Valorant) measurably improve reaction speed. Caffeine: 100–200mg reduces reaction time by 10–30ms temporarily. Monitor: A 144Hz+ monitor with low latency reduces visual delay significantly.
FAQ — REACTION TIME
Average: 200–250ms. Excellent: under 200ms. Elite (pro gamers): under 150ms.
Reaction time varies with fatigue, focus, and anticipation. Multiple rounds average out variance — 5 rounds gives a reliable score.
Yes. Action games improve visual processing speed. Studies show gamers react 50–100ms faster than non-gamers on average.
The world record visual reaction time is approximately 100ms. For sprinters, the minimum legal reaction time in the 100m dash is 100ms.
Yes. Results include ~5–15ms mouse latency and ~1–8ms monitor delay. A 144Hz+ monitor reduces display lag significantly. Your true neural reaction is slightly faster than the number shown.
Be well-rested, stay focused, and practice daily. Avoid anticipating the signal — early clicks are counted as failed rounds. Use a gaming mouse and high-refresh monitor for best results.
ABOUT STIMULATION CLICKER
🎯 What Is the Stimulation Clicker?
The Stimulation Clicker is an aim training game where colorful targets appear at random positions and you must click them before they disappear. It combines clicking speed with spatial precision — the same skill set required in FPS games like CS2, Valorant, and Fortnite.
It is directly inspired by professional aim trainers like Aimlabs and KovaaK's, designed to build mouse accuracy under time pressure.

FAQ — STIMULATION CLICKER
Yes. The mechanics directly mirror FPS target acquisition. Hard mode is comparable to professional aim trainer scenarios. Regular practice improves flick-shot accuracy in CS2 and Valorant.
On Medium difficulty: 1500+ points is average, 3500+ is skilled, 6000+ is elite. Hard mode scores above 3500 indicate pro-level aim.
15–20 minutes daily is optimal. More than 30 minutes causes fatigue that reduces accuracy. Consistent daily practice beats long occasional sessions.
ABOUT CLICK SPEED TEST
🖱️ What Is a CPS Test?
A Click Speed Test (CPS Test) measures how many times you can click per second. It's the core benchmark for competitive gaming, especially Minecraft PvP, where raw clicking speed gives a combat advantage. Our free CPS test offers 8 time durations (1s to 100s) and includes Normal and Challenge modes.

🖱 Clicking Techniques
Regular Clicking3–9 CPS
Standard one-finger method. Best aim accuracy. Sustainable for all durations including 100s.
Jitter Clicking10–14 CPS
Tense forearm and wrist to create rapid vibrations. Learnable with practice. Risk of wrist strain — take breaks every 15 min.
Butterfly Clicking15–25 CPS
Two fingers alternate on the same button. World record: 25.5 CPS (Nestor, 2022). Often banned in competitive servers.
Drag Clicking30–100+ CPS
Drag finger across button creating friction micro-clicks. Universally banned in competitive play.
FAQ — CLICK SPEED
6–7 CPS is average. Above 10 CPS is good. Above 14 CPS requires jitter or butterfly technique.
Extended sessions can cause wrist strain and carpal tunnel. Take breaks every 10–15 minutes. Stop if you feel pain.
Yes. A gaming mouse with 1000Hz polling rate and low debounce registers clicks faster. Most players gain 0.5–2 CPS from upgrading.
ABOUT SPACEBAR TEST
⌨️ What Is the Spacebar Speed Test?
The Spacebar Speed Test measures how many times per second you can press the spacebar. It's popular among rhythm game players (osu!, Beat Saber) and keyboard enthusiasts. Unlike mouse clicking, spacebar speed depends heavily on keyboard switch type and finger placement technique.
Our test supports 8 durations (1s–100s) and counts only new presses — holding down the spacebar does not register multiple presses.

FAQ — SPACEBAR
6–8 presses per second is average. Above 10 presses/sec is exceptional and typically requires a mechanical keyboard with linear switches.
Yes significantly. Linear mechanical switches (Red, Speed Silver) allow faster actuation than membrane keyboards. Switch actuation force and travel distance directly impact speed.
Browsers fire repeated keydown events when a key is held. We filter these with e.repeat detection — only actual new presses count, making the test fair and accurate.
ABOUT TYPING SPEED TEST
📝 What Is a Typing Speed Test (WPM)?
A Typing Speed Test measures your typing speed in WPM (Words Per Minute) and accuracy. The standard WPM formula counts each 5 characters as one "word." Our test uses real English words, tracks correct/incorrect entries, and gives live WPM feedback.
Choose 30s, 60s, or 120s modes. Average typing speed is 40–50 WPM. Professional typists reach 70–100+ WPM.

Yes. Mechanical keyboards with tactile feedback help accuracy. Low-profile laptops keys often cause more errors. However, technique matters far more than hardware.
ABOUT COREBALL GAME
🎮 How to Play Coreball
In Coreball, a central core spins continuously. You shoot balls from the bottom — each ball sticks to the core when it lands. The challenge: don't let your ball hit an existing ball already stuck on the core. As you score more, the core spins faster, increasing difficulty.
Tap or click to shoot. You start with 10 balls. Plan your shots carefully — timing is everything.
🎯 Coreball Tips
Watch the gaps: Focus on the spaces between stuck balls, not the balls themselves. Rhythm shooting: Find the rotation rhythm and shoot in sync. Don't rush: You have 10 balls — patience beats panic. Higher levels: Speed increases every 10 points. Adjust your timing accordingly.
FAQ — COREBALL
Coreball is a precision timing game where you shoot balls onto a spinning core without hitting existing balls. It tests timing, patience, and spatial awareness.
Scoring 10+ points without a miss is good. Above 20 is excellent. The game gets significantly harder past level 3 as rotation speed increases.
ABOUT DINOSAUR GAME
🦕 How to Play the Dinosaur Game
The Dinosaur Game (also known as the Chrome Dino or T-Rex Runner) is a classic endless runner. Press Space or tap to jump over cacti and duck under pterodactyls. The game speeds up over time — how far can you run?
This tests your reaction time and rhythm under escalating pressure, making it a fun complement to the reaction time test.
FAQ — DINO GAME
Originally created by Google, the T-Rex Runner appears in Chrome when you have no internet. It's now one of the most played browser games in the world, with an estimated 270 million plays per month.
Reaching 500 points is good for beginners. 1000+ is above average. Expert players regularly score 5000–10000+. The theoretical maximum score is 99999.
ABOUT NUMBER MEMORY TEST
🧠 What Is the Number Memory Test?
The Number Memory Test challenges you to memorize increasingly long sequences of digits. Each level adds one more digit — starting at 1, going up as far as your working memory allows. You have 3 lives; a wrong answer costs one life and drops you back a level. The number is shown briefly, then hidden — you must type it from memory.
This test directly measures your working memory capacity, one of the most researched cognitive abilities. It's used in IQ tests, psychology research, and neurological assessments worldwide.

💡 Tips to Improve Number Memory
Chunking: Group digits into pairs or triples (e.g. 3-8-4-7-2 → 38, 47, 2). This is how phone numbers are remembered. Rhythm: Say the number aloud with a rhythm or melody — music memory is stronger than verbal memory. Visualization: Associate digits with images or locations (memory palace technique). Practice: Daily training measurably expands working memory span within 2–4 weeks.
FAQ — NUMBER MEMORY
The average adult can hold 5–7 digits in working memory — this is why phone numbers were traditionally 7 digits long. The "magical number 7±2" was proposed by psychologist George Miller in 1956.
Memory athletes using the memory palace technique can memorize hundreds of digits. The world record for memorizing pi is over 70,000 digits. For random number sequences, competitive memorizers regularly achieve 50–100+ digits.
Yes. Working memory capacity is moderately correlated with fluid intelligence (IQ). Digit span tasks are included in WAIS and WISC intelligence tests. However, memory can be trained independently of IQ.
Display time scales with digit count (800ms per digit). At higher levels you get more time. The challenge is transferring what you see into short-term verbal memory fast enough — this is exactly what the test measures.
