What do you guys think are the easiest games available for a 4 or 5 yr old? I have a few that my niece loves - Fairies Fly, Archibald, PocketGod (though not really a game), etc. - but I'm looking for more. I want them to be simple because I don't want her to get too frustrated. A lot of the games I've looked at seem a little too advanced for her (some require reading for example) but she loves to play with my phone. Thanks in advance for any recommendations.
