Dock Stars is a free puzzle game developed by tyapp_games for Android devices. In this game, players are presented with a grid of colored numbers and are tasked with connecting them by drawing lines. The catch is that colored numbers can only be connected with other numbers of the same color.

The game is challenging and requires strategic thinking to complete each level. Players must carefully plan their moves to ensure they don't make any mistakes, but if they do, they can easily delete a line by drawing another line in between. With each level, the difficulty increases, and players must try harder to complete the puzzles. Dock Stars is a great game for puzzle enthusiasts who love a challenge.
