Leet Skills app for iPhone and iPad
Leet Skills is a collection of four mini games, each designed to challenge even the most elite ("leet" or "1337") gamers.
DISCLAIMER: This game requires some very nimble fingers, a sharp mind, and definitely some coordination between the two.
For reference, my high scores:
Hopz: 1310025814
Dodge: 2506
Mash: 354 (beaten by my friend, Aimee: 516)
Intel: 327
