Switch from single-shot bids to game-show rules.
Iterative guessing rewards binary search, whereas single-shot modes test your first price anchor. Guess the Price separates those skills into five distinct modes: bid once in Exact Price, judge a reference tag in Higher or Lower, pick the pricier item in Price Showdown, stay strictly at or under the tag in Don’t Go Over, or total three items in The Showcase.

Why relative percentage error matters on $28 and $699 tags.
Both games evaluate relative percentage error rather than raw dollars so a lower-priced pantry item and a $699 tech item demand proportional precision. On FoolFish, Exact Price and The Showcase use round(100 × exp(−3.2 × relativeError)) — a 2% miss scores 94 points while a 20% miss drops to 53 points.
