Lines on Sides

Join the tiles and experience an amazing adventure with them... no, wait, it's not that kind of game. :) Instead of saving the world once again, I present you a game in which you have to think about a solution. Your goal is to arrange the tiles so that their symbols match the symbols on the adjacent tiles.

Once you have achieved this, black lines will appear to indicate the correct placement of the tiles. By playing and thinking about the solution, you will either relax or... get frustrated. It depends on how good you are at solving puzzles.
