A few short weeks after superb puzzle game Threes was first released on iOS, it started earning clones. In a lengthy post on the games site, Threes designers recall finding the copies — straight clones, rip-offs, and games that were different, but not such as 1024 and 2048 — describing a process that made them sad. Particularly galling was the short time for clones and copies to be knocked together following Threes launch — not because the developers had wasted their time, but because they had spent 14 months tweaking and testing before hitting on a simple and glorious game, while the clones offered broken experiences.
