Anything really that doesn't fit into the main menu above.

The first ditloids appeared in Game Magazine in 1981 and were created by Will Shortz.

I've included his original ditloids here:

1 = W. on a U.
3 = B.M. (S.H.T.R.!)
4 = Q. in a G.
5 = D. in a Z.C.
7 = W. of the A.W.
8 = S. on a S.S.
9 = P. in the S.S.
11 = P. on a F.T.
12 = S. of the Z.
13 = S. on the A.F.
18 = H. on a G.C.
24 = H. in a D.
26 = L. of the A.
29 = D. in F. in a L.Y.
32 = D.F. at which W.F.
40 = D. and N. of the G.F.
54 = C. in a D. (with the J.)
57 = H.V.
64 = S. on a C.
88 = P.K.
90 = D. in a R.A.
200 = D. for P.G. in M.
1,000 = W. that a P. is W.
1,001 = A.N.
