After some testing you CAN set cloud variables to: - Any number - Numbers can optionally include one negative sign at the front and one decimal point anywhere that isn’t in front of the negative sign - A number value up to 256 characters - A blank value (“”) You CANNOT set cloud variables to: - Values containing letters - Invalid numbers (too many negative sign(s) and/or too many decimal point(s) and/or are in the wrong place) - “Infinity” (if you divide 1/0 scratch says it equals Infinity) - Anything else that is not a number You have to be “Scratcher” rank, not “New Scratcher” rank for cloud variables to work fully. (Unless you have certain JavaScript hacks, then it’s possible for New Scratchers to set cloud variables)
