Warning: Accessing this software emulator requires jailbreaking your iPhone, or enabling it to run third-party homebrew applications. Capable of playing homemade diversions -- and over 1000 classic Nintendo Entertainment System (NES) games, from Metroid to Gunsmoke -- it's worth the effort, though. Highlights include horizontal/vertical views, on-screen buttons to poke, and the ability to save games at will, a major advantage in hair-pullers like Castlevania and Ninja Gaiden.
A candy-colored puzzler challenging a voracious orange blob called Biggs to guzzle insects and spit them back at rows of hungry creatures waiting above. Play for cartoon visuals and whimsical sound bytes, stay for addictive extras like bug-popping bonuses and "Food Chain" combos, activated by nudging creatures into increasingly larger predators' maws. High price tag aside ($8), it's sure to preoccupy you for weeks on end.
