How to play PassportQ
PassportQ is a free daily city guessing game in the same spirit as Wordle: each morning a new mystery city goes live somewhere in the world, and you have five guesses to figure out where it is.
- Read today's temperature and population.The opening clues show the mystery city's daily high and broad city size, which immediately narrows the climate zone and scale.
- Guess a city. Start typing any city name. The autocomplete handles common alternates, accented characters, and frequent misspellings.
- Use the distance and compass feedback. Wrong guesses show how far off you are and which direction the answer lies in, so you can triangulate.
- Unlock the next clue. After each wrong guess you get one more piece of information: elevation, then local time, then landscape, then top airlines.
- Solve in five. Lock in the right city before your five guesses run out to keep your streak alive. Missed it? The answer is revealed and you can still play the other daily games.
What is PassportQ?
The first clues are the mystery city's high temperature for the day and its population tier. Every wrong guess unlocks the next piece of information: elevation, local time, landscape, and top airlines.
Wrong guesses also show the great-circle distance and the compass direction to the right answer, so even when you miss, the next guess is meaningfully closer. Most players solve the puzzle in three or four. The harder days lean on second-tier cities like Lyon, Porto, Ljubljana, and Kaohsiung, where knowing your regional hubs really pays off. No sign-up is required. The whole thing takes under two minutes on a phone. Browse the broader daily geography games set, compare other games like Globle, or try SkyQ (guess the flight), AirportQ (find the hidden airport from destinations), AirlineQ (name the airport from its airlines), CityQ (3×3 geography grid), or RailQ (trains worldwide).
Reading the climate clue
Temperature is the single most powerful clue in PassportQ and it is always shown from the start alongside population. The trick is reading it against the calendar. A high of 30 degrees Celsius in January means the Southern Hemisphere or the tropics, which cuts the world map almost in half before you have even typed a guess. A high of 5 degrees in July means somewhere unusually cold for that time of year, which points to high altitude or near-polar cities like the Andean capitals, the Tibetan Plateau, Patagonia, or the Norwegian coast.
Pair the temperature with population first, then use elevation as soon as it unlocks. A warm coastal megacity is a completely different shortlist from a warm highland city. Above 2,500 meters the world narrows to a handful of usual suspects: La Paz, Cusco, Quito, Bogota, Lhasa, Addis Ababa. Below 10 meters tends to point at coastal or delta cities, especially in Northern Europe or Southeast Asia. By the time local time and landscape land, you usually only need to confirm a region rather than search one.
Capital cities by continent
The PassportQ city pool is global by design. Africa is represented by Cairo, Lagos, Nairobi, Cape Town, Marrakech, and Addis Ababa, plus a long tail of regional capitals like Dakar, Kigali, and Windhoek. Asia leans heavy on East and Southeast Asia, with Tokyo, Seoul, Bangkok, Singapore, Hanoi, and Kuala Lumpur as anchors. South Asia adds Mumbai, Delhi, Karachi, Dhaka, Colombo, and Kathmandu, and Central Asia rounds it out with Tashkent, Almaty, and Baku.
Europe covers the obvious national capitals plus a deliberate selection of second cities: Lyon and Marseille in France, Hamburg and Munich in Germany, Porto in Portugal, Thessaloniki in Greece, and Lviv in Ukraine. The Americas include the major capitals north and south alongside regional favorites like Quebec City, Buenos Aires, Medellin, and Salvador. Oceania is the smallest pool but includes both metro hubs and remote outliers like Hobart, Christchurch, and Noumea, which is where the puzzle gets genuinely hard.
