While most iPhone games are designed to waste time, Nimble Strong actually teaches you something useful—like how to mix over 70 cocktails. Plus, the whole thing has a dark, anime-styled storyline to make learning fun.
Nimble Strong also seems to take the learning end seriously. Joystiq writes:
But it’s not enough to select the right ingredients, you’ve got to have perfect timing to put just the right amount into each drink. For example, if the customer wants a Black Russian, you’ll select the ice bucket and hold your finger on the pictured old-fashioned glass until ice just reaches the rim. Then you’ll tap the e-liquor cabinet and add 2 oz. of vodka (hold on the screen for two seconds) and 1 oz. coffee liquor (one second) then serve. The better your mix (you get bonuses for perfect pours) and the faster you can mix up the drink, the bigger your tip. It won’t just jangle in your e-pocket, though: you’ll be able to use that cash to unlock the 75+ recipes that can be accessed outside the story mode.
There’s even certificate that you can earn upon completion—printable of course, and worthy of that spot on the wall next to your college diploma.
