Super Why is an interactive, educational reading game for preschoolers based on the hit PBS Kids show of the same name, featuring (much to the delight of Super Why fans, no doubt) many of the original sounds, games, and characters from the show.
Super Why gives you four different character-narrated, touch-based games, each with a different task for kids: Super Why's Story Saver (picking one of three words to correctly complete a sentence), Princess Presto's Wands-Up Writing (identifying letters by sound to spell a word, then tracing those letters with your finger), Alpha Pig's Lickety Letter Hunt (choosing letters to spell a word), and Wonder Red's Rhyming Time (matching words with their rhyming counterparts). The games offer a variety of good challenges, and most seem to be well-tested and preschooler-friendly in terms of interface and difficulty level. The only noticeable shortcoming is the fact that Princess Presto's coaching requires you to draw a letter in a particular way, which might be at odds with how kids have learned to draw the same letter elsewhere.
All of the games are short and modular--perfect for short attention spans--so kids can stop before finishing even one iteration of a game, or they can keep playing as long as they're interested. A "Play All" option serves up random games. After every game (which can last less than a minute), players earn a virtual sticker, which they can then play with on the game's "Super Duper Computer" (another nod to the show), accumulating a collection of stickers that work like touch-based stamps on four different, erasable backgrounds.
The iPad and iPhone/iPod Touch versions of this game are nearly identical (the iPad version has better graphics), and both are a solid value for parents who want an engaging educational game with repeat play value.
