ode to the triple word score

[metaphorliteral]

The crossword game is what I choose to play,
to lay my words in lines across the board.
High-scoring letters in my hand won't stay
when I craft a triple-scoring word.
Oh triple word score! In corners you lurk,
and in the center of the board's outer edges.
When played across, you provide the best perk,
and push us up to fulfill winning pledges.
When used correctly, how points multiply,
assuming it's not some two-point word waste.
My friend's played across two at once-- what a guy,
who crafts his words with care and not with haste.
Oh triple word score, Scrabble player's friend,
play the word "zax" and the game may as well end.
