Two items appear — pick the one you think costs more, and both real prices are revealed. The Rookie level starts with easy, obvious gaps: 10 quick questions to test your sense of price.
It's a price-comparison quiz: two items are shown side by side, and you pick the one you think costs more. As soon as you choose, both real prices are revealed and you find out whether you were right. After 10 questions you get a score for how many you nailed.
Everything is built from items known worldwide — no country-specific stuff — so it plays the same in Korea, the US, or Japan. Prices are shown in each region's own currency (won, dollars, yen).
Rookie is the easiest of five levels. It uses pairs with obvious gaps — a pencil vs. a bicycle, a cup of coffee vs. a laptop — so it's a relaxed way to check your sense of price.
Even the easy ones make you go 'oh, that's what it costs' as the real numbers pop up. The gaps get tighter as levels rise, so start at Rookie and climb from there.
It's great for a quick mental break, or for a friendly contest over who guesses prices better. You can share your result by link, so a friend can try the same questions.
Beyond the fun of guessing right, you pick up the real prices of everyday things you usually overlook. It's just for fun — but you'll come away with a slightly sharper eye for value.
