A round gives you ten arrows at a target on the right of the range. You loose an arrow by clicking where you want it to go, but two things stand between the click and the landing point: a crosswind that pushes the arrow sideways, and a slow drift that moves the target itself. Every arrow that lands stays on the face so you can see your grouping.
The target has five rings, worth 10 points on the outer red, then 20, 30 and 40 as you move in, with 50 for the gold centre. An arrow that lands outside the outer ring scores nothing. There is no penalty beyond the arrow it costs, so the round is always exactly ten shots and the maximum is 500. When the last arrow is spent the round closes and Best is updated if you beat your previous total.
The wind offsets every shot sideways. The stronger the reading at the top of the range, the further the arrow drifts.
Ten per round. After the tenth the round ends and your total is compared with Best.
