Hmmmm....for my first go, I got

    T R I A D (0 green, 0 yellow)
    H O N E S (0 green, 0 yellow)
    C L U M P (0 green, 2 yellow)
    B U L K Y (3 green, 0 yellow)
    F U L L Y (4 green, 0 yellow)
    G U L L Y (5 green, 0 yellow)

Looking at the similarities, I'm wondering if the adversarial nature will generally lead to higher-than-naively-expected frequencies of:

Words with 'y', as people will tend to 'eliminate' the common vowels early, leaving 'y' as a 'substitute vowel' to fill in.

Words with repeated and doubled letters, as a round progresses and the pool ov available letters shrinks.

I wonder what other patterns might emerge from the ruleset?

I agree. My word was "HIPPY." I don't know how you would exploit it though.
