๐๏ธ Symmetry Detection Test: Spot the Mirror in the Noise
Sixty identical dots flash inside a circle for about a third of a second before a scatter of fresh dots wipes them away. All you have to say is whether they were mirrored left to right across the vertical centre line, or simply thrown about at random. Round by round the share of mirrored dots drops and the noise rises, so the signal keeps fading. There are 25 rounds, and since a correct call adds 80 points while a wrong one takes 80 away, guessing never builds a score. Answering fast multiplies the final total by up to 1.5, for a maximum of 3000 points.
๐ก How to play โ Sixty identical dots flash inside a circle for about a third of a second, then a scatter of fresh dots wipes them away. In that instant you have to tell whether the dots were mirrored left to right across the centre line, or simply thrown about at random. Each round hides a little less symmetry in a little more noise, so the calls get harder as you go. A right answer is worth 80 points and a wrong one costs 80, so guessing averages out to nothing โ only what you genuinely see adds up. Answering fast multiplies your total by up to 1.5, for a maximum of 3000 points.
