Using Game Theory To Win ‘Words With Friends’

“Words With Friends,” the Scrabble game knock-off for your smart phone or laptop, attracts nearly 7 million players a day. The game is so addictive that actor Alec Baldwin infamously got kicked off a plane in December for refusing to stop playing it!

But how do you win? William Spaniel has studied that question and written several e-books on the topic. The PhD student in political science at the University of Rochester says you can use concepts from game theory to win Words With Friends. Game theory is a method of analyzing how to proceed in certain situations and it is usually used in economics, political science, and psychology, so how can you use it to win a virtual board game?

Spaniel says that WWF is a zero-sum game, meaning that you don’t want to make any play that will help your opponent. He says you always have to be analyzing the choices that your opponent will make, and it’s more important to play words that will lead to fewer points for your opponent rather than more points for you.

    Lexulous is so much better, amazing that WWF is so popular

  • Rachel

    The word “jo” is one of my favorite Scrabble words. It means sweetheart.

  • Derek

    This is what drives me crazy about this game and guarantees that I won’t play it  Za?  Qi?  If those are allowed then there should be a special rule that the next player can play the letters BS for an automatic win.  Characters from another alphabet and words from another language aren’t supposed to count.

      Qi is a legitimate word, but I agree some of the things friends come up with are really just ‘scrabble words’ …

       Just because you do not know them does not mean they are not part of the english language.

    “Za” is a pizza, I belive.

    A fave word of mine in WWF!

    The best word can’t be suggested unless we can see your board!

    Hi Friends, This is producer, Kevin Sullivan, and it turns out I mistook my V for a U!! So that sort of changes things, so the letters I have are actually W-R-I-O-V-T-F. I’ve attached an image of the board. Just click on it to see it larger. And as you can see, we could use some help!

    VOW at B1, forming OBE and WOE. It scores 30, which is decent, and let  you keep common letters which is good.

    Also, EA’s official Scrabble app is better than Words with Friends.

    Really, there are two options here. The “instinct” is likely to be B1 VOW (for 30)- the leave is FIRT,
    which has decent but not awful synergy- certainly the best we’re going
    to get out of this drossy rack. The bag (AAEIIIOUUUDDDGHMNNPQRRSTTTY?)
    contains ten vowels and seventeen consonants, in addition to a blank-
    and only one E. This means that our odds of bingoing are very low
    despite the blank, especially on his board- which means we should be
    hitting hotspots and largely ignore bingo lanes like playing in column K
    (OFF or OFT) would support. Holding the F also threatens G5, which is
    likely to be lower-scoring but potentially could tilt the game in a
    close, low-scoring endgame.

    That said, there is a pretty argument to be made for G1 VOT(E)R scoring
    28- which is to say, it plays off another consonant and blocks off
    opponent’s biggest threat- QI in that same spot. It opens a triple lane-
    suicide in WWF (seriously: the board geometry in this game blows), but
    the odds of opponent making a play in that lane isn’t very high because of the remaining unseen tiles. Opponent is likely not to be afraid of a six letter play from the Q consider what he can probably see remaining.

    But VOTER falls apart upon examination: he probably has a U or more that needs dumping (if he has the Q, QUIT/OFT is a completely reasonable play given the number of Is, Us, and Ts out). If he doesn’t, he should assume that WE have a U and thus be less likely to open up that lane. It also gives up the O with only one left for the B1 hotspot. There’s not really a whole lot we can do about the threat of BILKING or BILKERS. We just have to hope we fish the S or blank or E (or G!) to lower the number of possibilities at that spot. And, with VOW, we keep the F- which means we can play along that 14th row if he does make either of those plays.

    This one’s not even a contest – VOW / Obe / Woe is the best play by far.

When author Judy Blume published her “Tales of a Fourth Grade Nothing” in 1972, she introduced the world to Fudge, a toddler who makes his older brother Peter’s life miserable. We look back on the book with Blume.

The Appian Road, in the Monti Aurunci area of Italy. (Robert Kaster/University of Chicago Press)

For many people, this time of year is an occasion for road trips — up and down the coasts, across the U.S., through Europe. For Robert Kaster, it was a time to venture along the most ancient roads of all time: the Appian Way in Italy.
