There are various "cue cards" to collect throughout the game, and once you have, you can unlock the bonus puzzles as an extra. Chillingo claims that Jim and Frank boasts over 20 hours of gameplay, and that sounds pretty accurate. Though there is no multiplayer option, the game holds four profiles and is enabled with online leader boards through Crystal, if you need to feel a little competition.

Though the game seems geared more toward the elementary school set, it's challenging and multidimensional enough to entertain adults as well. Make sure to download the Jim & Frank Mysteries soon, before that incredible $1 introductory price goes up.
