Deranking is a term used in the rhythm game osu!, a massive multiplayer online rhythm game created by Australian developer Dean Herbert. In this game, the ability to aim to the notes plays a larger factor than having to hit the notes accurately. See, the main system of ranking players based on skill in osu! is a system developed by Tom94, called ppv2. In this system, aim plays a large factor in determining ones skill level. This system is in fact used in many tournaments to help improve the competitive integrity to a large amount of players in these tournaments. By deranking, a player can essentially cheat the system, being able to aim maps better than those that actually belong at their rank. Professional osu! player Digitalhypno has recently created a tournament, called "Hippo Cup" for players ranked 1k-20k. Many people are excited to see which group of derankers will be able to take the title of Hippo Cup Champion.
