Whether you are a seasoned geography buff or just curious about the world, Ultimate Playground's World category has something for you. Our three geography games each challenge a different skill — population estimation, country statistics, and visual city recognition — so you can mix up your sessions and never get bored.
Two cities appear side by side. Which one is larger? Once you pick, a slider lets you estimate the exact population. CityMix blends binary decision-making with a numerical estimation mechanic, making every round feel unique even when you revisit cities you've already seen.
Does France have a higher GDP than Argentina? Is Canada's coastline longer than Norway's? Higher or Lower puts two countries head to head across six different statistics — population, GDP, area, coastline, life expectancy and more. A perfect game for anyone who loves data and world geography.
A city photo and its name appear on screen. Your job: click the correct country on the interactive world map before the timer runs out. With 100 cities across 68 countries and continents, City Mapper tests your spatial geography knowledge in a fast-paced, visual format.
Hotel Price takes the World category in a new direction. Real hotel photos from Booking.com appear alongside the city, star rating and amenities — your job is to estimate what the room costs per night in USD using a logarithmic slider. Battle rounds pit two hotels from the same price tier against each other, so you can't just pick the obvious luxury winner. Hotels span budget guesthouses in Hanoi and Medellín through to five-star suites in New York, Santorini and Dubai.
All four World games support real-time multiplayer. Both players face the same questions thanks to a shared seed, so the competition is always fair. Race to out-guess your opponent and claim the top score.
