where? maybe for 7-10 year old kids but even low games that have only 1 referee will be played with offside (at least thats my experience playing until the age of 16) i think the DFB (german football association) requires 3 referees starting from the 7th or 8th league. and below that they just dont have the manpower.

you're right, by amateur I meant the first level of engaging with sport, not amateur leagues. sorry for the confusion. made an edit.
