it might be a bit weird but it changes the chance of its numbers so im not gonna complain it works if you put negitave numbers so you cant confuse it unless you use letters. even then, if you put letters in there it will only do rock and error, so even that cant stop me.
look at top left to see what you and scratch cat chose, 1 = rock, 2 = paper and 3 = scissors. basic rock paper scissors rules, rock beats scissors, paper beats rock, scissors beats paper. biggest string is around 350 blocks btw and maybe even more since it doesnt count the hexagon and circle things.
