Before you is an exciting game of attention and logic, your main task in Smile Line Filler is to pair identical figures, but in such a way that there are no free cells in the arena.
Imagine a square playing field in front of you, and colored figures are scattered in the corners. They need to be paired with one line so that all the free space is occupied and simultaneously does not block the path to other things. You will come across figures in the form of stars, hearts, moons, circles, and different fun shapes. The first levels are simple enough for the player to get the hang of it and practice. Further, with the development in the stages, folding puzzles will become more difficult, so you need to try.
The good news is that the game has no time limits, and your actions are free. For example, if you understand that you must combine the pairs correctly, you can remove your line and shift it differently. At the end of the levels, you can choose whether to complete the task again or move on. The choice is yours!
