About this game

■Welcome to "How Many Dots?", the ultimate brain training application for modern people living in the digital age.

In today's society, where all kinds of information are pre-processed as text and numbers due to the widespread use of smartphones, we may have let our inherent ability to intuitively grasp quantities lie dormant. When waiting in line at the checkout, we can often intuitively tell which line is moving the fastest, or we can instantly estimate the number of scattered documents. We call this skill—the ability to directly perceive "quantity" without relying on numerical symbols—"Quantity Sense."

This app, "How Many Dots?", focuses on this "Quantity Sense" that modern people often overlook. It's a brain training app designed to help you develop the ability to accurately perceive quantities from fleeting visual information in a fun, game-like way, in a long-term, and scientifically effective manner. There are no unnecessary effects or complex rules. You only need to spend a few seconds to a few tens of seconds in front of the screen. Unleash the full potential of your brain's visual processing abilities and transform instantaneous intuition into supreme pleasure. Start your intellectual and exciting experience now!

■ Why "9, 10, 11"? A game design that overturns conventional wisdom about number perception.

Most number guessing games and educational apps for young children start with simple levels, like 1 to 5 objects, easily countable at a glance. In cognitive psychology, the ability to instantly and accurately grasp up to 4-5 objects without counting is called "subtizing," and this is considered a primitive function inherent in the human brain.

However, "How Many Dots?" aims to awaken true "number perception." Therefore, it deliberately focuses on the extremely subtle and thrilling number range of "9, 10, and 11," numbers that the human brain cannot easily distinguish at a glance.


The numbers 9, 10, and 11, when randomly placed, are impossible to determine accurately just by looking at them. However, counting "1, 2, 3..." on your fingers would be impossible within the game's time limit. By constantly striving to navigate this boundary—where the dots are uncountable but distinctly different in their clusters—the visual cortex and prefrontal cortex of the brain begin to work at full capacity. By mobilizing all visual sensors—the overall silhouette of the dots, the nuances of density, the empty space—a keen, inexpressible sense of "this feels like 11" or "this scattering is closer to 9" is honed. This exquisite difficulty, combined with the brain's satisfaction upon hitting the target, is the biggest secret to its addictive nature.

■A simple and refined game flow that anyone can master in 1 second

The app's controls are designed to be simple, efficient, and beautifully designed, eliminating any potential stumbling blocks. From children to seniors, anyone can start playing without hesitation the moment they launch the app. The basic game flow is as follows:

1. Select a difficulty level: Tap the menu on the screen to select a difficulty level that matches your skill level.

2. Press the start button: Tap "Start" when you are ready. Focus on the blank white canvas in the center of the screen.

3. Dots flash for a moment: Bright blue dots will appear randomly on the canvas. The dots will disappear instantly once the time limit (depending on the difficulty level) has elapsed, so you must not blink and imprint the entire screen on your memory.

4. Choose intuitively from three options: Once the dots disappear, three buttons, "9," "10," and "11," will appear at the bottom of the screen, along with the question, "How many dots were there?" Rather than overthinking it, the key to a high score is to trust the afterimage on your retina immediately after the dots disappear and your first impression, and tap quickly.

5. Results and answer check: Pressing a button will immediately display feedback such as "Correct!" or "Too bad!", revealing the actual number of dots. The game achieves a perfect tempo, making you want to press the "play again" button again and again, not only feeling the joy of getting the answer right, but also thinking "I'll concentrate more next time" when you make a mistake.

■Four difficulty levels designed to push the limits of your brain, each with its own unique character

"How many dots?" offers four different difficulty levels, catering to everyone from beginners to brain training professionals, and even those who want to challenge themselves to perform godlike feats beyond human limits. A key feature is that the display time of the dots differs significantly in each mode, allowing you to progress at your own pace.

Beginner Mode: Display Time 3.0 seconds
Start here. While 3 seconds may seem long, it's surprisingly just enough time to accurately count the random dots. It's ideal for warming up, allowing your brain to adapt to seeing the dots as "blocks of numbers" while you leisurely observe their arrangement.

Intermediate Mode: Display Time 2.0 seconds
In the intermediate mode, the first real challenge, the display time is shortened to 2 seconds. There's no more time to count in your head. This requires training to broaden your field of vision and capture the entire canvas as a single photograph, like pressing the shutter button on a camera.

Advanced Mode: Display Time 1.0 Second
This is a truly professional-level speed, with a display time of just one second. There is absolutely no time for logical thinking with the left brain. Enjoy the thrilling challenge of fully utilizing the right brain's image processing ability and catching the density of dots and spatial balance with your primal intuition.

Genius Mode: Display Time 0.5 Seconds
This "Genius Mode" is the pinnacle, pushing the limits of human cognitive speed. The display time is a mere 0.5 seconds, approaching the limits of human cognitive speed. You must literally identify it the instant a blue shadow flashes in the corner of your vision. Those who can answer correctly can be said to have acquired a godlike sense of quantity.

■The effects of quantity sense training that will change your daily life are something we highly recommend for people like you

This app goes beyond being just a time-killing game; it has the potential to boost your performance in daily life, business, and learning. For example, this is especially recommended for those with the following challenges or goals:

* Those who have recently found it difficult to recall things quickly and want to start brain training.
* Those who feel their field of vision has narrowed due to excessive desk work or smartphone use.
* Business professionals who want to hone their "intuition" to instantly grasp the key points of data and materials in meetings and business negotiations.
* Students who want to refresh their minds and improve their concentration during breaks from exams and studying.
* Seniors who want to maintain cognitive function, such as maintaining a high level of dynamic visual acuity and instantaneous judgment.

At first, you may feel frustrated because it's "too difficult and you can't get it right at all," but as you play the game 5 or 10 times a day, you will surely feel new circuits that were dormant in your brain starting to connect. Please experience the comfort of intuitively grasping the world as "quantity" without the need for numbers.

The human brain possesses a wonderful property called "plasticity," which means it evolves endlessly the more you use it. Even if you were completely outmatched yesterday despite being in 0.5-second genius mode, if you keep playing diligently every day and improve your stats, one day you'll experience a miraculous moment when the number of dots suddenly becomes a clear "visual block" that leaps into your brain. Design, engineering, and cognitive science—all beautifully harmonized in "How Many Dots?", let's embark on a wonderful journey to expand the possibilities of your brain.
