Hello Kitty Cafe!

Even though the basic idea of taking orders and serving customers is simple, this game might be confusing and hectic for kids. Players have to pay attention to the many bubbles popping up that show different options and needs. The pace ramps up pretty quickly, with customers getting angry and walking out after only a few seconds by "Day 2" of gameplay. Players can hire help and choose from a wide range of upgrades, which must be purchased with in-app currency.

There are in-app purchases for "points," one of the game's currencies (the other currency is dollars, earned through gameplay). Players can also earn points for "free" by watching videos with ads, viewing other apps on the Tapjoy advertising platform, or playing a gambling-style spinner. In some ways, the entire app is a promotion for the Hello Kitty brand. The developer's logo appears on the main screen and other ads appear throughout the game.

Some privacy concerns. Players can opt in to Apple's Game Center to track scores and achievements, and for some games, challenge friends. Players can send and receive friend requests using an email address or Game Center nickname, revealing the first and last name associated with each party's Apple ID and, in the case of email requests, the sender's email address. With iOS 5, players can opt to have a private or public profile, which can include a photo. With a public profile, your real name is visible to all other players, and Game Center will recommend you to other players using your real name. With a private profile, only your friends can see your real name, and Game Center will not recommend you to other players.
