Welcome to Cat’s Delivery Service! This is a simple yet charming puzzle game where you guide adorable cats into their matching boxes. Each cat waits patiently on the rail. Your task is to slide and arrange the boxes inside the board so that the box with the correct color or shape aligns perfectly with the cat’s position. Once a match is made, the cat jumps into the box — and your delivery is complete! The challenge comes from the layout of the boxes. You’ll need to think carefully about their shapes, how they fit together, and the limited space inside the board. Sometimes one wrong move will block another cat’s path!
