The Global High Scores as viewed in-game
The Global High Scores on the website
The High Scores is an in-game and website feature which ranks players depending on the player's position and their reputation. There currently appears to be no requirements for players to be ranked on the high scores. Jagex Moderator's accounts also appear on the high scores, which is not usually the case in other Jagex games such as RuneScape and FunOrb.
The high scores update once every six hours, so a players current rank may be different from their actual rank due to the outdated high scores.
