A Bongard Problem is a problem where you have 6 symbols on either side of a line. The symbols on the left follow a certain rule, while the symbols on the right do not follow it. The objective is to find this rule.
I have made 5 Bongard problems for the community. I have enumerated the symbols so that it will be easier to reference/discuss them. The numbers themselves are not part of the symbols and should be ignored when applying the rule in question.
Now tell me, what are the six rules?
Rule 5: The number of ____ is one more than a multiple of 3.
