SEE:

Qay'mol         puzzle (n) 

(Lieven, qepHom 2018):  like a jigsaw puzzle or those metal hoops that need to be untangled or any puzzle that involves a physical object or objects that must be manipulated

(De'vID < MO, 1/22/2019):  When a piece of a jigsaw puzzle fits into the right spot, you can say: Qay'mol mey (Qay'mol) teSra' "the (puzzle) piece fits (into) the puzzle".  (In this context, you don't have to repeat Qay'mol, but it's fine if you do.)  Or nelchu' Qay'mol teSra' "the puzzle piece fits perfectly".  The first focuses on the interlocking of the pieces; the second focuses on the piece in question occupying the identically shaped space where it goes.

teSra'                  tile (n) 

(Lieven < MO, 12/02/2018):  teSra' is a piece of a puzzle or a Scrabble game and so on.  The difference to the 'echletHom is basically that a playing card is bendable while a  teSra' is hard.
