CostcoGuessr

CostcoGuessr is an unofficial fan game about Costco prices. Its product pool comes from Costco warehouses in many countries, among them the United States, Canada, the United Kingdom, Sweden, Japan, South Korea, Taiwan and Australia. Each item is shown with its photo, its full name and pack size, and the flag of the country whose store sells it.

The daily game is a set of ten rounds tied to the date in New York, so every player gets the same pairs. In each round two products appear side by side, often from two different countries, and you tap the one with the higher price. A row of ten cells under the cards fills in as you go, and at the end you get a score out of ten that you can copy and share.

Practice deals fresh random pairs for as long as you like, Settings lets you change how fast the game moves on to the next round, and the menu shows a countdown to the next daily. There is no sign-up and no ads.

The pairs are rarely obvious: a pallet of 252 jars of jelly sweets from a Korean warehouse can sit beside two bags of Japanese noodles, so pack sizes and local price levels matter as much as the product. It suits Costco regulars, bargain hunters and anyone curious about what bulk goods cost in other countries.
