The initial grid with all the letters and bars is shown here for information. The extra letters in wordplay spelt out “vertices; Necker cube; erase all else except pips”. Lines drawn between cells containing the letters of VERTICES formed a Necker cube, a framework that can be seen as a three-dimensional cube in two different orientations. The grid letters were erased apart from all occurrences of O, representing dice pips in correct positions on a cubic die. The extra words in clues were based on terms for dice numbers, as shown below. Entries with the letters of VERT_CES included, or with the Necker cube itself erased, were accepted.
Conventions: * = anagram, < = reversal
