Today’s free flash game is a pretty polished rendition of the classic 501 darts, in which you have to score a total of 501 (every point you make is deducted from 501, until you get to 0, then you win the game). It’s more challenging than it sounds, since you can’t finish if your last score if you scored higher than the remaining (e.g. if you only need 2 points and you scored a 4, it’s not counted)
The game used the left mouse button exclusively – drag it and release. It takes some getting used to at first, but once you get the hang of it, you’ll find that it’s actually a decent simulation of throwing darts.
