How to play

  1. Each of the 10 rounds shows a line with its two ends labelled, and a target number.
  2. Move the marker to where the target belongs. Targets can be whole numbers, negatives, decimals or fractions like 3/4.
  3. Lock in to reveal the true position (green), how far off you were, and your points.
  4. Scoring: 100 for a near-exact hit, falling to 0 once you are 20% of the line away.
  5. Later rounds use trickier ranges and fewer tick marks. Aim for 1000.
