Darts is my hobby and I have a lots of friends who share it.
I’ve seen exceptional players who can calculate x01 games really fast. However I’ve also seen people dealing with calculations and having a hard time
when the checkout time arrived. So I sent a little tool to play x01 games and leaving the players the fun part without the math part.
It allows to set double in/out for 301, 501, 701 and 901 games
