Code Club developed Wurm Online, a massively multiplayer online sandbox game, and its successor, Wurm Unlimited.

History
Code Club AB was founded as Mojang Specifications AB by Swedish video game designers Rolf Jansson and Markus Persson in 2007, as their game, Wurm Online, began to turn a profit. Later in 2007, Markus Persson stepped out of the project and left the company. However, he wished to retain the "Mojang" name for himself, leading Jansson to rename the company Onetoofree AB. Jansson had issues explaining the name to others without having to spell it out, wherefore the company assumed a new name, Code Club AB, in October 2011. On 8 July 2019, Stockholm-based Game Chest acquired 82.9% of Code Club for SEK3.37 million (US$335,000), of which SEK1.5 million in cash and SEK1.87 million in newly issued Game Chest shares.
