Here is a game that strikes me as a good example of what would be an Ouverture Facile game on android.
Something that put a spin on the tool you are using to play the game.
A really good idea IMHO, if you are looking for something different and meta to play on your phone.
Not riddle based but intriguing for those who likes meta-game like In Memoriam and such.
