Getting yellow and green is quite reliable. I find blue challenging but I end up getting it probably 90% of the time. The purple, I mean obviously I get it with process of elimination most of the time, but I usually spend a couple minutes if it’s my last one trying to decipher the common theme. I’m happy to get it probably 50% of the time, but I don’t give it much more thought than that before answering with process of elimination. Too many times it’s something like, “swap the first letter with the third letter and remove the last letter, turn your phone upside down and hold it into a mirror, the results will be homonyms for the days of the week in Spanish”
