Are you good at math? Don't worry here is an app that will keep score for you or up to four players. Darts 301 is played from 301 points to zero. The only thing to keep in mind is that the game can only be won by closing with a double score! The app will keep score and check if you finish with a double or not! You can also check if the score is right each round by looking at the dart board in the app and it should look identical to your dart board. Have fun!
