🎮 Area Estimation Test: Which Shape Is Actually Bigger?

💡 How to play — Two shapes appear side by side and you pick the one with the larger actual area. They are deliberately different shapes, colours and tilts, because length and outline are the traps — a long thin rectangle can easily look bigger than a compact circle of the same area. Over ten rounds the gap narrows from 35% down to under 5%. Since there are only two options, a wrong pick subtracts exactly what a correct one would have earned, so guessing is worth nothing.
