About this game

Quadrix is a fast, captivating color-matching puzzle where every second counts. Spot four dots of the same color, connect them into a rectangle, and clear the board before your timer hits zero!

🎮 How to Play
Select & Match: Tap any colored dot on the grid. Cells that can pair with it will light up with a golden outline.
