## What is Grid Toggle Puzzle?

Think smart. Toggle wisely. Solve the board.
This is a unique puzzle game where your objective is simple: make all buttons share the same state — either ON or OFF.
But every tap creates a chain reaction!
Each button affects others depending on the puzzle mode. To solve the board, you must carefully plan your moves and understand how each pattern works.
Different Puzzle Modes
Every level introduces different toggle mechanics to challenge your logic:
• PLUS (+) – toggles buttons in a plus-shaped pattern
• X Shape – affects buttons diagonally
• O Shape – creates circular toggle patterns
• Row & Column – flips an entire row and column at once
Mastering these patterns is the key to solving increasingly difficult puzzles.
