It looks like it plays a lot like the War Games app. This was VERY good. Got it as a free AOTD on Amazon: https://play.google.com/store/apps/details?id=com.berad.wargames&hl=en_US
They're (mostly) time killers. Personally I think Trainyard is probably the most challenging of the bunch.
WarGames - Very LOOSELY Based on the movie; Think; Trainyard EX; 4 Pics 1 Word *Edit: Formatting
Hacker & Data Hacker games also (both totally different).
If nothing else, there's mobile WarGames.
Ohhh, release date 2015. Hmm. Will look around but I'm guessing /u/Zerothaught got it.
