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 tetromino always has the digit 0, which affects how line sums are formed.
