How to Play
Doubles Practice keeps it simple: you're given a randomly generated double, anywhere from D1 to D20, and get three darts to hit it. Once your three darts are thrown (or you've hit it), the game rolls a new random double and you go again, with your hit rate tracked across the session.
Why It Helps Your Game
Doubles win and lose matches, and yet most players only ever practise the doubles they already like. Because the target here is random every time, you can't cherry-pick your comfortable numbers: you're forced to build real confidence across the whole board, including the awkward doubles you'd normally dodge in a casual practice session. Tracking your hit rate over time gives you an honest number to chase, rather than a vague sense of "my doubles are alright."
