About

C

Features
Read full description

C-Line is an addictive puzzle game about connecting similar items. The player can move one ball per turn, and the player may only move a ball to a particular place if there is a path between the current position and the desired cell. The goal is to remove balls by forming horizontal, vertical or diagonal lines. New balls are coming pretty fast.
