I have been playing the game for the past couple of years & I also wondered to begin with, how is it possible for these people to score these many words, in such a short span.
I also started slowly & picked up steadily and now able to make over 60-70 words per game & some/many-times go over 100, my best being 126 words. This mostly happens in a speed round, where every word is worth 13 points, be it a 4 letters word or 10 letters word.
I also notice few champions, who come out of the blue, on top of the leaderboard, with no.1 ranking but its hard to sustain that via cheating. Since many words are repeated, plus practice makes you perfect, as there are certain patterns in every game, good players are able to pick on them and score heavily.
But I find it hard to fathom calling these players genius, as they are doing this day in day out, thus able to use patterns to make big scores but there are handful of players, who start off with a bang & last the course and become real big players, as they end up scoring heavily, perhaps due to their better grasp of English & power to make words at a high speed, thus their high positions in every game.
I find myself still unable to sustain the consistency, which comes with practice only, of course an ability to make words with time constraint is totally helpful. I still fluctuate from a top 10 finish to top 50-60 finish in the next game, much to my dismay.
In a nutshell, I would like to call this a game of practice & very few geniuses play this regularly, as I am yet to see Discopidgeon playing, despite having him in my frenemies list for long.
Few floaters, who cheat their way to the top & get lost equally fast, don't rule the roost at Wordament and some quality players, who are very regular, daily participants, are the ones taking Wordament to new heights but it would be a mistake to call them geniuses, only practice is making them perfect, at least in picking words on regular basis.
Its a great fun to take part & see one's name in the top 10, one strives to achieve that as much as possible but so do the others & that's how this competition lives on, with very few geninues & cheaters in small numbers.
