Scoring
Every round is scored from 0 to 100. Exact is 100, and each test has a miss that scores 50: 20% off on Count, 8% of the wall on Track, 6° on Angle, 3% of the line on Split. On Timing it depends on the target: 1 second off scores about 53 on a 5 s target and 84 on a 15 s one. Small misses cost little (half that miss still scores 78), bigger ones fall away fast (double scores 14, triple about 3).
Rooms
One person hosts and shares the 4-letter code. Everyone sees the same puzzle at the same moment and locks in a guess; the round ends when everyone has answered or time runs out. The reveal puts every guess on one drawing, and the highest total at the end wins.
Daily puzzle
One puzzle of each test, the same for everyone, new each day at midnight. You get one go.
