Lines on Sides2021

Arrange the tiles so that their sides match each other in colors. Your task is to arrange the tiles correctly so that each side of them is the same color as the adjacent tiles. When the tiles are properly arranged, black lines appear between them. As a minimalistic game, there are no tutorials or tips in it. You have to understand each mechanic for yourself and use it to solve puzzles. Good luck.
