Angry Birds works just fine. So do all the other games as per the below screen shot.
But I have found plenty that aren’t working with the Passport square screen. So whilst gaming is possible on the Passport, you might want to check if you can play the types of games you prefer first or buy a different phone.
Also the top right of the phone got hot whilst playing many games.
To be honest I was expecting a greater number not to work with the square screen so I was overall pleased with the selection that I tried that ended up working.
