Worldle, a geography based version of Wordle, is perfect for travel lovers

Wordle, the online word game, has taken the world by storm.

Originally created by software developer Josh Wardle for his girlfriend, the small project became so popular in just a couple of months that the New York Times purchased it, reportedly for a "low seven figure" sum.

Its success has resulted in dozens of other games based on the original (itself a word-based version of the old code-breaking board game, Master Mind).

Now there's a new version that will particularly appeal to travel lovers: Worldle.

Worldle, created by a France-based web developer who goes by the Twitter handle @teuteuf, it offers players the map outline of a country. It's up to you to work out which country it is.

Rather than tell you whether you have any letters correct in the country's name, Worldle tells you how close your guess is, geographically, to the answer. Like Wordle, you can only play it once a day and you get only six guesses to identify the country.

You can play it here.

It's a wonderful way to test your knowledge of geography and particularly challenging when it comes to the landlocked countries of eastern Europe or central Africa (despite a 100 per cent success rate on Wordle, my success rate on Worldle after two days is only 50 per cent).

Although it was created in late January, the Worldle exploded in popularity over the past week, with @teuteuf tweeting that more than half a million people played the game on Monday.
