A free app for Android, by TIG STUDIO.
This free puzzle game lets you choose from a variety of different themes, including the lovely realm of mahjong, as well as the world of pictures, where you can explore and interact with many different objects.
It is a very simple game at the beginning, but it will get more and more challenging as you progress, with many different elements and obstacles that will test your skills.
The gameplay consists of just one single button, which is used to tap and match tiles. This will remove them from the board, and it is the only way to get rid of them.
