It's been about two years since I paid any real attention to iOS gaming: I bought a Vita and the seemingly unstoppable trend of free to play games put paid to that. But this Xmas one of my brother-in-laws gave me £15 of iOS credit. Can anyone suggest some games (that you buy once and that's more or less it) for someone with a couple of days to kill with the in-laws (they have no TV or music in the house!?!)? My mind is so numb I'll give anything a go apart from trading card games. Thanks in advance.
