I don't feel strongly enough about them to vote (where's the "shrugs" option?) but generally I find fiddle-with-stuff-and-see-what-happens puzzles work better at the table than riddling wordplay. You definitely don't want them to be barrier that can stop progress altogether, but presenting them as a less dangerous option than some other way to move on is probably okay. There's at least a couple of fantasy stories where the protag gets stuck on sphinx's riddle and goes on to intimidate, bribe or just beat it to death instead. Options with higher risk/costs are good.
