## What is -1?

This is a brick elimination game. When you tap on a brick, it will split into new bricks in the surrounding empty spaces. The number on each new brick will be one less than the original brick's number.

If a newly split brick touches another brick with the same number, it will trigger a chain reaction, eliminating all connected matching bricks. The total sum of the numbers on the eliminated bricks will be added to your score.

After each brick-splitting action, new bricks will be added to the screen. The game ends when the screen is completely filled with bricks, and your final score will be calculated.

Your score will be uploaded to the leaderboard, allowing you to see how strong your skills are!
