### 🧠 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!
