The hiscores are rebuilt every five minutes from what the game has saved, so a character that’s being played shows its progress after its next save, up to about 20 minutes later. Guests and staff aren’t on them. To take your character off, type /hiscores off in the game, and /hiscores on to put it back.
Hiscores
Every character's levels, XP and rank in each skill. Look one up, compare two, or browse the tables.
