World of Tanks (WoT) is an armoured warfare-themed multiplayer online game developed by Wargaming, featuring 20th century (1910s–1970s) era combat vehicles. It is built upon a freemium business model where the game is free-to-play, but participants also have the option of paying a fee for use of "premium" features. The focus is on player vs. player gameplay with each player controlling an armored vehicle, from the time of Pre-World War 2 to the Cold War-era.

Wargaming Group Limited is a global video game company headquartered in Nicosia, Cyprus. The group operates across more than 16 offices and development studios globally. Initially focused on turn-based strategy and real-time strategy games, Wargaming switched to developing free-to-play online action games in 2009, including the military-themed team-based game World of Tanks, and later World of Warships, World of Warships Legends, World of Warplanes, World of Tanks Blitz, and World of Warships Blitz.
