Field notes
Players can type a price or use a slider, then follow higher-or-lower arrows and color-coded distance feedback across six guesses. Three hints are available, and the page says using one is reflected in the shareable result. It also describes streaks and guess distributions stored locally, while linking to an archive, answers, and guides.
