I know the Spel from the PC and there also makes it quite fun. Smartphone (in my case a Samsung Galaxy S3) is only of limited use due to the much smaller screen this app. The watching is strenuous and only up close really possible. To operate the menus, the shop and the puzzle itself some precision then necessary, which will be frustig in later levels of difficulty with a lack of time.
So the overall complexion as a PC port. Unfortunately, smartphones have not 4: 3 Bildschirmverhaeltnis and are not 20 inches tall. Who calls a Tablet his own, but you should risk a look.
