I recently came across your posting and thought you might find this helpful.
“Here's a way to possibly improve OUTSPELL scores: First, make a list of 13-letter words that satisfy a certain rule. You might begin with a list which contains words like these five: AMBIDEXTERITY, DEMAGNETIZERS, AGROFORESTERS, DECLASSIFYING, and DECARBONIZERS. The rule to employ when building your list is to pick 13-letter words which can be started with a 3-letter word which then can be added to, both front and back, to gradually build up the entire 13-letter word. As an example, these five can be started with, respectively, DEX, NET, FOR, ASS, and BON.
And with these five an entire 13-letter word can be constructed: DEX, DEXTER, DEXTERITY, AMBIDEXTERITY; NET, MAGNET, MAGNETIZE, MAGNETIZER, MAGNETIZERS, DEMAGNETIZERS; FOR, FOREST, FORESTER, FORESTERS, AGROFORESTERS; ASS, LASS, CLASS, CLASSIFY, CLASSIFYING, DECLASSIFYING; BON, CARBON, CARBONIZE, CARBONIZER, CARBONIZERS, DECARBONIZERS. Get the idea? By the way, build the word horizontally, using high scoring tiles (like Q, X, or Z) in positions 4 and/or 10 where applicable.
Creating a LONG list of candidate 13-letter words makes it easier to obtain a starting point since your initial rack of letters is obtained randomly. Reloading the game will provide you with a new randomized rack of letters if you’d like to improve your chance of getting off to a good start.
Once you successfully construct an entire 13-letter word, you’ll be able to improve your scores, likely obtaining scores well over 1000. Of course, LUCK is still a factor, but your odds are better; also, EXCHANGING some or all letters often improves your odds as well.
Although stating the obvious, holding BLANK tiles for later use in making Q, X, or Z out of them is key to success as well.”
Just this past week a user who employs this method and makes the OUTSPELL scoreboard frequently passed the above information on to me and I’m eager to attempt it myself to see if I, too, with a little LUCK, can make the scoreboard.
