Round by round
A round scores 100 for a guess within a small margin of the truth and falls in a straight line to 0 for a wild one; the day is the average of the five. The pictures are the game — these are the figures behind them.
- Meet. If these two lines carried on, where would they meet? The lines meet at 40°, after carrying on 1.0 and 1.0 times their drawn lengths.
- Aim. Where will the arrow hit the wall? The arrow’s line had to be carried on 3.2 times the arrow’s own length to reach the wall.
- Share. What percent of the shape is colored? The shape was an L, cut by a straight line: 24% of it colored, 76% not.
- Center. This arc is part of a circle. Where is its center? The arc was 149° of its circle, 41% of the way round. The shorter the arc, the less it says about its center.
- Mix. What percent of the dots are green? 103 of the 124 dots were green and 21 were not: 83%.
