## What is WABO?

Overview:
WABO is a unique twist on classic game, incorporating a prime number mechanic.
Each block has an assigned digit, and whenever a full horizontal line's sum is prime, that line disappears.
You can choose from three difficulty levels (Easy, Medium, Hard), which alter the numeric range and add variety for both newcomers and experienced players.

Features:
The I-shaped block always has the digit 0, which affects how line sums are formed.
Every time you clear a line, the sum of its digits is added to your total. At Game Over, see how high your total score is.
As a browser extension, you can play instantly with a single click.

How to Play:
Select a difficulty and start the game.
Use the keyboard or on-screen buttons to move and rotate block.
If the sum of a full row is prime, that row disappears and contributes to your score.
When no more pieces can be placed, it's Game Over—check your final total of cleared digits.
