This month's Wired included a short feature on Ryan Tibshirani, a Stanford statistics student who figured out how to game a... game. He built an algorithm that will help you win at darts, even if you suck. 

The game of High Score places high-valued areas close to duds -- if you risk going for a bullseye, you might end up with much less. So, depending on how accurately you can throw a dart, you ought to adjust your strategy. 

Take about 50 shots at a dart board and then input the results at their applet. It'll generate a "heat map" which will show you roughly where you're best off aiming. 

Or, if you already know that you're horrible at darts -- here's my heat map! Amateurs like you and me should aim a little south-west of middle if you find yourself playing darts over the holidays.
