Angry, upset, irate, duped — Wordle knock-offs leave fans of free game fuming

The wildly popular puzzle game Wordle has found itself in the middle of unexpected controversy this week as knock-off versions are trying to make a buck from the free game.

Developed barely two months ago by software developer Josh Wardle for his puzzle-loving wife, the basics of the game are quite simple: players must take guesses to correctly spell a five-letter word. In under six guesses, players use clues to decipher the word of the day, which is the same one for every player in the world that day.

Guess a correct letter in the correct place and the game turns the letter green. A correct letter in the wrong place is yellow, and any letters that aren't in the word are greyed out. That's it.

This simple concept has exploded this month, from a few dozen of Wardle's friends and family playing in November to almost three million people participating this week.

Wardle's game is free to play and based in a web browser, a move that inadvertently opened the door to a number of imitators to launch app-based versions on Apple and Google devices, most of which try to get users to pay to play.

One such version, by New York-based app developer Zach Shakked, has earned particular ire online, since he was so blatant about it, even tweeting what he was up to and gleefully reporting on the number of people downloading his game, which sold for $29.99 US.

While Shakked has gained the most recognition, he is far from the only one to try. Roughly a dozen apps have sprung up on the App store in recent weeks, most of which ape the look, feel and concept of Wordle, while conveniently adding a price tag. Most of them mysteriously started to disappear from Apple's App Store starting on Tuesday, as the online outrage started to spread.

Apple confirmed to CBC News that the company removed a number of Wordle-like apps this week. As of Wednesday morning, only one game with the word "Wordle" in its title was still available to download, and that was an unrelated children's game from 2017, where users have to spell as many words as they can out of a set of letters, within a set time period.

A look at the the App Store's user agreement suggests why the others have been purged.

"Don't simply copy the latest popular app ... or make some minor changes to another app's name or UI [user interface] and pass it off as your own," the company advises. "In addition to risking an intellectual property infringement claim, it makes the App Store harder to navigate and just isn't fair to your fellow developers."

Not surprisingly, Shakked has been besieged with criticism online. Julian Sanchez from Kitchener, Ont., says the stunt is emblematic of the problems of the tech sector as a whole.

"That drive to look at things that work already and try to find a way to insert themselves so that they can make money is the core of the tech industry," Sanchez told CBC News. "It's not really geared around solving large problems — it's about trying to take a slice of the pie."

Sanchez said there's no need for the knock-offs. "People are loving [Wordle] and it works, but god forbid something be free and fun and no one make money off of it."

To fans of the game, the original free version has been a great form of self-care in getting through the pandemic. Torontonian Adam Kertesz says he got hooked on the game the first time he played it, and has quickly turned his friends and family into dedicated players, too.
