In an eight queens square, blanks represent eight chess queens such that no queen is in a position to capture any of the others; it is up to you to determine where on the 8×8 grid those blanks are. Eight queens squares are inherently double. For example:
PEN•PSIS
PROSIT•O
•AVENUES
STEVENS•
HOLE•TCM
A•TRASHY
LOYAL•EM
EX•LEERY
Forms can combine some of these various types. For example, here is a bigram consonantless square (with original words shown):
UE OO IA uneconomical
OO UO EY colobus monkey
IA EY EA vintage year
