hi! this is such a cool ttrpg and i'm prepping to run a first session with some friends but i'm just a little confused - when rolling for stats (STR/DEX/CTRL), is it 1d6 per stat or 3d6 per stat? the wording tripped me up

I definitely need to make more clarity. This is not the first time this question came up. 

3d6 str

3d6 dex

3dx CTRL
