eh usually people set out first day according to strength/rating! Set out in numbers 1,2,3....etc
then usually you can challenge people within a range of usually 2 people above you but no more! Then if you win (and only win) you swap positions with them on the ladder. So if number 10 challenges number 8 and wins then they swap places on the ladder so now number 10 is now number 8.
Also you cant reject challenges to keep your spot as admin will kill you or just kick you from ladder. Also some other terms where you have to play atleast 1 every time period.
