Components
This is an open source game created by Uberspot and this app is also able to sharpen the brain for the user.
Proposal
Here I suggest that in addition to feature settings (Bacground, Grid, Empty tile)
Mockups / Examples
Before

After

if the user select sttings feature

If the user select bacground

If the user select grid

Ifthe user select empty tile

If the user has selected all the matching colors according to their respective likes, then the game will look like this

Benefits
Usefulness or rather the benefits of this feature settings are: the user can choose some features for more interesting game appearance :
* Bacground is to facilitate users in replacing the bacground color.
* Grid is to facilitate the user in replacing the grid color.
* Empty tile is to facilitate the user in replacing the color of the empty tile.
