Every so often, your uncoordinated hands get wrangled into a game of barroom darts. If you'd like a better chance at victory instead of apologies, a few Stanford students' web app can analyse your game and provides your personal best-chance target.
As Wired's write-up explains, darts is a game where the difference between hitting a 20 or a 1 is very, very small, and always aiming at the bullseye isn't a good long-term strategy. Facing down his own non-expert tossing skills, Ryan Tibshirani wrote an app that analyses 50 of your throws and figures out where you should aim for your best chances at a high score.
The web app requires Java to run, and doesn't account specifically for specialty games like cricket — although, in most games, a high score is never a bad thing. If you've got your own strategies for faking it like a billiards room hero, tell us about it in the comments.
