If you have access to the web, chances are you’ve heard of Wordle by now. The online word game, which gives players six chances to decipher an unknown five-letter word, has become the internet’s latest obsession—so much so that it’s already inspired countless spinoffs.
One such spinoff was designed with travelers in mind: Airportle. Created by Scott’s Cheap Flights, an online service that helps travelers find the best deals on airfare, Airportle works just like Wordle, but instead of guessing words, players are tasked with deciphering airport codes. After submitting their first guess, players will see the letters they’ve chosen highlighted one of three colors: green if the letter is correct and in the correct spot, yellow if the letter appears in the airport code but in a different position, and gray if the letter does not appear in the code.
