Full description
### 🧠 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. --- 📝 Summary "Yakubun Block" is more than just a puzzle—it’s a game that satisfies your intellectual curiosity while sharpening your mind. Strategically use the 1000-point bonus to wipe the field and climb the leaderboard! **Download now and experience the thrill of the "Reduction"!**
