About this game

### 🧠 A New Sensation in Brain Training! "Yakubun Block"

"Yakubun Block" is a fresh, addictive brain-training puzzle game where you manipulate falling number blocks and combine them with those on the field to perform "reductions." Test your mathematical knowledge and reflexes!

#### 🎮 Game Overview: Clear Blocks with Reductions!

The goal is simple: drop falling number blocks onto columns where the field blocks share a common divisor. The numbers will then be divided by their **Greatest Common Divisor (GCD)**—this is "reduction."

* Blocks disappear when their number reaches **"1."** * Stack blocks to earn points. If the blocks reach the top of the field, it’s Game Over!

✨ 6 Reasons You’ll Love "Yakubun Block"

1. 🤓 Master Common Divisors and Prime Numbers!

This game demands instant recognition of numbers and their relationships.

* **Quick Judgment:** Looking at the falling block and the field, you must instantly decide: "Do these share a common divisor of 2 or more?"
* **Knowledge Retention:** As you play, you’ll naturally memorize primes (2, 3, 5, 7, 11...) and composite numbers, improving your math skills while having fun.

2. 🚀 The Ultimate Brain Workout

Speed and accuracy are the keys to success.

* Calculate the most efficient reduction and look for potential chain reactions in the split second before a block lands.
* Fully engage your spatial recognition and decision-making skills to find the perfect spot for every block.

3. 💥 The 1000-Point Mega Bonus: The "+1" Strategy! 【NEW!】

Every time you hit a 1000-point milestone, a powerful bonus triggers that changes the game!

* **Conquer Primes:** The system adds **"+1"** to every single block currently on the field. This turns those pesky, hard-to-reduce prime numbers into **even numbers**!
* **Explosive Chain Reactions:** Watch in awe as the field undergoes a massive wave of automatic reductions. It’s the ultimate feeling of satisfaction to see a cluttered field cleared in seconds.
* **Bonus Points:** All points earned during this "Plus One" cascade are added to your score, making 1000 points the perfect springboard for a new high score.

4. 📶 Play Anywhere, Anytime – 100% Offline!

No internet connection is required during gameplay (except for the initial download and ads).

* Play on subways, in the mountains, or anywhere without worrying about data charges.
* Optimized for low battery consumption, so you can enjoy longer sessions on the go.

5. 🌙 Eye-Friendly, Low-Brightness Design

We care about your eye health during long play sessions.

* **Dark-Themed Aesthetic:** The game features a low-glare color palette, making it comfortable to play at night or in dark environments.
* **Reduced Fatigue:** By minimizing flashy flickers, we’ve created an environment where you can focus deeply on the numbers without straining your eyes.

6. ⚙️ Customizable Difficulty for All Skill Levels

Tailor the challenge to your own pace.

* **Level Adjustment:** Use the seek bar in the settings to change the maximum number generated (e.g., set it to 50 for numbers between 2 and 50).
* **Beginner to Pro:** Beginners can start with low numbers to learn the ropes, while math enthusiasts can crank it up to the max to test their lightning-fast factoring skills.
