## What is Pen It! Zen Master?

Can you find all the cows? Challenge your brain with a colorful logic twist!

Welcome to Cow Logic, a refreshing puzzle game inspired by the legendary "8 Queens" problem. Forget the chessboard and the crowns—it’s time to head to the farm!

The Challenge:
Your mission is simple but brain-teasing: place a cow in each region of the grid. But watch out for the rules! To solve the puzzle, you must ensure:

One Cow per Row: No two cows can share the same horizontal line.

One Cow per Column: No two cows can share the same vertical line.

One Cow per Color: Every colored zone must contain exactly one cow.

No Neighbors: Cows are picky! They cannot be placed in adjacent squares (including diagonals).

Why You’ll Love It:

Smart Difficulty: Starts easy for beginners and becomes a true brain-burner for puzzle pros.

Clean Design: Beautiful, minimalist colors and cute cow icons that make problem-solving a joy.

Daily Mental Workout: Perfect for keeping your mind sharp during commutes or coffee breaks.

No Pressure: Play at your own pace with no timers—just pure logic.
