GR8CTZ - Great Cities of the World - is an educational and addictive city guessing geography game. You can play against your friends or alone against the clock. The Street View of an iconic location in one of Top 40 cities appears on a TV screen via Chromecast; each out of up to 4 players can try and guess the city. Your goal is to guess more cities than your opponents in the shortest time and with the least number of guesses.
The game can be played in English, Dutch, French, German, Italian, Portuguese, Russian, or Spanish.
If you don't have a Chromecast device, the only use of this App would be its Daydream service, and the beautiful Daydream it is: the rotating Street View of a random city, which changes every couple minutes. The iconic spots of the cities are shown and the names are slowly revealed. It shows the current time too, so one might consider it useful as well.
If you like the game you'll love the full (paid) version of the game (GR8CTZ for Chromecast) in which you can look around and walk about in any subset of 175+ cities from Acapulco to Yaroslavl. Whether or not you have Chromecast, you can check the Web version of the game at http://gr8ctz.com. The Web version has been used by geography teachers around the world (see classroom recommendations at http://www.teachersfirst.com/single.cfm?id=15153) and was played by thousands of people in 75 countries.
