If you want to challenge your mind, Grid Games is the most appropriate option, since it combines several reasoning games: sudoku, crosswords, and takuzu, among other puzzle games.

Graphics:
The interface, though well-organized, is unattractive; what's more, the screen background has a strong color that hurts your eyes. The graphics are simple, without much attention to detail.
Controls:
To select the type of game, you must touch the screen with your finger. If you want to zoom in just make the pinching move (on devices that support it); to write, you need to use the keyboard available on the bottom of the screen.
