Bullet chess is a variant of chess that is played with time controls that are faster than 3 minutes per player. It is the quickest variant of "speed chess" and is faster than blitz chess. The rules for a bullet chess game are not different from those of a normal chess game. The most popular forms of bullet chess are 1|0 (one minute with no increment per player) or 2|1 (two minutes with a one-second increment per player). Bullet chess is played online and has millions of followers worldwide. The use of increment in bullet chess is primarily to avoid issues with latency as well as so-called "dirty flagging". The term "lightning" can also be applied to this variant. The key differences between bullet chess and other variants of chess are the time controls and the speed of play. In bullet chess, players have to make quick decisions and move their pieces fast to avoid running out of time. Bullet chess is meant for everyone, regardless of skill level.
