Alphabetic would be great, you will have to adjust the settings (options to very easy - very easy/easy). i love this one b/c it reinforces their letters and I get so frustrated when I can't beat my 10 year old (at higher settings, of course). FallDown is another simple game that my kids love. My entire family is addicted to Veggie Samurai. My 6 year old son likes Dismount...I'm not a big fan but it's harmless (not violent) and he gets a kick out of it. btw, these are all free apps. I haven't paid for an app yet but am sure that day is getting close...Enjoy.
