It's pretty simple once you figure out how it works.
Quick easy example:
You select a random word, "Jello". You score a 4 likeliness. Next word the line down is "Hello" followed by the word "Quack" a line after that. Knowing that you scored a 4 with "Jello" you know your answer is "hello".
If you select a random word, let's say its "Hater" and it has two likeliness, that means two of those letters are not only the same but in the exact correct location. So just go down the list and compare every word to "Hater", you rule out every word that doesn't have at least two letters exactly in the same position as "hater", so you are almost always left with just one or two choices. Let's say you see another word, "taser" and you select that and still, it's only 2 likeness. So now you have a lot to work with. Another line down you see "Later" and another is "boner". You know its not "later" because the first two words you selected only have two letters in the same spot and process of elimination so knowing that the answer is "boner".
Another trick is you see a lot of junk characters between words, like [{<>|\[]{}>)>[ . This is just a trick and not necessary but it can make it easier and reset your tries.
If you ever see closed brackets, like this [ ] or ( ) or < > you can actually highlight it, select it and it will either remove duds (incorrect words from the puzzle) or reset your tries. It does not count as a try by selecting them either, so if you are ever on ur second or third guess and still not sure the answer, go through the junk and select the closed brackets. The game will highlight it for you so just scroll through the junk until it highlights. Sometimes they can be long too, so it might look like }>>>[^\>[¢>>}>))))((((] (you see the bolded closed brackets in there [ ] ).
