Hint 1:


  • $\begingroup$ You might want to narrow it down a bit. There are lots of possibilities. $\endgroup$ – Engineer Toast Jun 19 '15 at 15:52
  • $\begingroup$ I'd buy that, yeah. I wasn't worried about easy, I was worried about there being too many answers that made sense. The hint ties is down almost completely. $\endgroup$ – Engineer Toast Jun 19 '15 at 15:59

T Q P H H O _ _ _

N D H: Triangle Quadrilateral Pentagon Hexagon Heptagon Octagon Nonagon Decagon Hendecagon

T C O D _

I: Tetrahedron Cube Octahedron Dodecahedron Icosahedron

  • $\begingroup$ Quadrangle and Quadrilateral had a mighty battle and Quadrangle was winning for over 200 years but it has fallen out of favor and Quadrilateral took the only to be overtaken again in the last few years! $\endgroup$ – Engineer Toast Jun 19 '15 at 15:55
  • $\begingroup$ The missing letter for #2 is I, for reasons similar to the first, just in a higher mode of thinking.... $\endgroup$ – Set Big O Jun 19 '15 at 15:57
  • $\begingroup$ @EngineerToast Thanks. I wasn't sure which to pick, but I've changed it now $\endgroup$ – Spencerkatty Jun 19 '15 at 16:01
  • $\begingroup$ @Geobits Yeah, just wasn't sure what the other one was, wanted to get an answer in first $\endgroup$ – Spencerkatty Jun 19 '15 at 16:03

    $\begingroup$ @JLee: That's because he's being facetious. Still got farther than I did though. $\endgroup$ – Mark Peters Jun 19 '15 at 15:44
  • $\begingroup$ +1 for pointing out how broad it is in the form of an answer $\endgroup$ – Engineer Toast Jun 19 '15 at 15:51
