Can’t: Create original puzzles

It turns out a version of Sumplete already exists.

Gizmodo’s Carlos Zahumenszky reports again, this time on the origins of ChatGPT’s Sumplete:

Sumplete is basically identical to two games that have been available in Apple and Google’s app stores for some time now. One of those games is Summer, which has been available in Google’s Play Store since 2020. Summer’s rules are the same as Sumplete’s. The goal is to eliminate numbers on a grid until you reach the target sum in every row and column.

But Summer wasn’t an original idea, either. In fact, Summer was likely based on Rullo, an identical game that’s been available on the App Store since 2019. Does this mean that Summer copied Rullo and that ChatGPT copied both of them and then had the gall to tell Tait that it was an entirely new game? Well, not exactly.

Summer and Rullo are simply mobile versions of a traditional paper game known as Kakuro. In fact, RP Apps and Games, the small studio that developed Summer, explicitly states on its Google Play page that its app is based on Kakuro. When it comes to Kakuro, well, that’s a copy, too. According to The Art of Puzzles, a blog by puzzle creator Grandmaster Puzzles, Kakuro is the Japanese name for a game originally called Cross Sums. The name “Kakuro” is an abbreviation of the phrase “Kasan Kurosu,” which literally means “cross sums” in Japanese.
