Google has made Google Assistant available on IOS. You can play a few games with it and all are accessible! As of now I think this may only be in the US store with others coming soon. This app is free to use with no adds. You can make Mad Libs, play trivia games, play an emoji movie guessing game, and some other things! There are these things too chat bots maybe? That you can interact with. One try’s to guess the character you are thinking of by asking yes or no questions. Another is a more in-depth trivia game to name a few. Link to the IOS app below.
