How to Play

121+ starts you at 121: finish on a double, same as any leg. Check it out successfully and the target climbs by one, to 122, then 123, and so on, so the game gets harder the better you play. Miss your checkout three times running and the target resets back down to 121, so there's a real cost to a cold streak, not just a missed dart.

Why It Helps Your Game

This is finishing practice with a built-in difficulty curve: it keeps raising the bar for as long as you keep clearing it, so you're always working right at the edge of what you can currently do rather than repeating the same comfortable checkout. Because a bad run sends you all the way back to 121, it also rewards consistency over a single lucky dart, which is exactly the discipline that separates a decent finisher from a reliable one.
