Dices (5)
I believe the answer is:
cubes
'dices' is the definition.
('cube' can be a synonym of 'dice')
This is the entire clue.
(Other definitions for cubes that I've seen before include "1, 8, 27 etc" , "Three-dimensional shapes with six sides" , "Geometrical solids" , "Solid bodies" , "figures" .)
